## Motivation

<!-- Author statement: This Motivation section was written only after all other sections of the document were completed, so that it reflects the full scope of the topic. -->

A deep squat means lowering the hips until the thighs rest on the calves with the heels on the ground. It is used in two ways: as a resting posture held for minutes at a time, and as a strength exercise taken through its full range. Much of the world still rests, works, and uses the toilet in this position, while many people raised on chairs lose the ability to sit in it. It draws interest because one movement combines leg strength, hip and ankle mobility, and an everyday posture.

For decades, coaches and some physicians warned that bending the knees below thigh-level strained the joints, and that warning shaped how strength training was taught. Interest returned as training studies compared squat depths, as researchers watched hunter-gatherers rest in squats rather than chairs, and as the ability to get down to the floor and back up was studied as a marker of aging well.

This review examines the evidence on deep squatting for muscle strength and everyday mobility, weighs it against concerns about knee wear, and describes how the practice is applied and monitored.

Expert discussions and research papers that give a high-level overview of deep squatting, its knee safety, and its place in daily movement.

<!-- Search statement: On 2026-10-21 a real-time search was run with WebSearch (general queries such as "deep squat", plus site-restricted queries for "squat" on peterattiamd.com, hubermanlab.com, foundmyfitness.com, chriskresser.com, lifespan.io and lifeextension.com) and on-site searches (peterattiamd.com/?s=squat showed "Nothing Found" in the page body but its search overlay listed 45 squat results; hubermanlab.com episode pages were fetched and their transcripts scanned for "squat"). Findings: Huberman Lab's Kelly Starrett episode discusses floor sitting, squatting and the overhead squat at length (38 transcript mentions); the Ido Portal episode mentions squatting only briefly. Lifespan.io's only relevant article summarizes a single squat-versus-walk sitting-break trial with unspecified squat depth; a QA audit judged it not a high-level discussion of deep squatting and it was replaced by the Squat University post on deep squats and knee safety (Aaron Horschig), which is also cited in Historical Context. Peter Attia's AMA #32 audio is members-only, but its free preview page carries the full show notes, including a section on squatting technique and heel elevation. FoundMyFitness covers squats only as "exercise snacks" and in a Kelly Starrett interview that would duplicate the Huberman item's expert. Chris Kresser and Life Extension pages mention squats only in passing or in generic exercise lists. A narrative review (Hartmann 2013) and a primary study (Raichlen 2020) were added as qualifying items. -->

## Systematic Reviews

Systematic reviews and meta-analyses on squat depth and range of motion, and on the joint risks and childbirth outcomes of squatting.

- [Effects of range of motion on resistance training adaptations: A systematic review and meta-analysis](https://pubmed.ncbi.nlm.nih.gov/34170576/) - Pallarés et al., 2021

  Across 16 studies, full-range training increased strength and lower-limb muscle size more than partial-range training; functional-performance differences were not significant.

- [Which ROMs Lead to Rome? A Systematic Review of the Effects of Range of Motion on Muscle Hypertrophy](https://pubmed.ncbi.nlm.nih.gov/36662126/) - Kassiano et al., 2023

  Across 11 range-of-motion (ROM) studies, full squats grew buttock and inner-thigh muscles more than shallow squats; partial repetitions near the bottom grew front thighs similarly.

- [Occupational Risk in Knee Osteoarthritis: A Systematic Review and Meta-Analysis of Observational Studies](https://pubmed.ncbi.nlm.nih.gov/32638548/) - Wang et al., 2020

  Eighty observational studies: occupational squatting, kneeling, and lifting were each associated with higher odds of knee osteoarthritis (joint cartilage wear) than sedentary work.

- [Occupational risk factors for meniscal lesions: a systematic review and meta-analysis](https://pubmed.ncbi.nlm.nih.gov/34911509/) - Bahns et al., 2021

  Pooled observational data link work-related squatting to roughly doubled odds of meniscal lesions (tears of the knee's cartilage pads); evidence quality moderate to low.

- [Squatting position in the second stage of labor: A systematic review and meta-analysis](https://pubmed.ncbi.nlm.nih.gov/32966958/) - Dokmak et al., 2020

  Seven randomized trials: squatting during childbirth reduced instrument-assisted deliveries but increased caesarean sections, with no net benefit shown.

  
## Mechanism of Action

A deep squat takes the hips, knees, and ankles close to their end ranges, with knee bending beyond about 120° ([Galvin et al., 2018](https://pubmed.ncbi.nlm.nih.gov/29802075/)). Its proposed effects run through five channels:

- **Muscle work at long lengths:** At the bottom, the gluteus maximus (main buttock muscle) and adductors (inner-thigh muscles) produce force while stretched. Training at longer muscle lengths may drive more growth than training at short lengths, though the evidence is mixed ([Wolf et al., 2026](https://pubmed.ncbi.nlm.nih.gov/41646176/)).
- **Knee loading, two competing views:** One view holds that compression between thighbone and shinbone and behind the kneecap rises as the knee bends, peaking near full depth and stressing the menisci and ligaments ([Escamilla, 2001](https://pubmed.ncbi.nlm.nih.gov/11194098/)). The opposing view holds that beyond about 90°, contact between thigh and calf and the wrapping of the thigh-muscle tendon over the thighbone spread the load and lower stress behind the kneecap, and that cartilage and ligaments adapt to graded loading ([Hartmann et al., 2013](https://pubmed.ncbi.nlm.nih.gov/23821469/)).
- **Active rest:** Resting in a squat needs more leg-muscle activity than chair sitting ([Raichlen et al., 2020](https://pubmed.ncbi.nlm.nih.gov/32152112/)); contracting muscle draws glucose from the blood partly independent of insulin.
- **Bowel emptying:** Deep hip bending relaxes the puborectalis (a muscle sling around the rectum) and straightens the anorectal angle (the bend between rectum and anal canal).
- **Circulation:** Squatting compresses leg blood vessels and raises blood pressure; standing up releases blood into the legs and briefly lowers it ([Krediet et al., 2007](https://pubmed.ncbi.nlm.nih.gov/17561808/)).

  
## Historical Context & Evolution

Squatting is one of humanity's oldest resting postures, used for eating, working, toileting, and childbirth long before chairs. It remains everyday behavior in much of Asia and Africa: in a Beijing survey, about 40% of men and 68% of women recalled squatting an hour or more daily at age 25 ([Zhang et al., 2004](https://pubmed.ncbi.nlm.nih.gov/15077301/)).

The full squat also became a staple of weightlifting. Karl Klein's 1961 report is not indexed in PubMed or available online; [a Squat University history of the controversy](https://squatuniversity.com/2016/01/22/debunking-squat-myths-are-deep-squats-bad-for-the-knees/) recounts that, using a self-built device, he described looser knee ligaments in deep-squatting weightlifters and advised stopping at thigh-parallel; school, military, and medical bodies then discouraged deep knee bends. Later measurements with a standard arthrometer (a device that measures knee looseness) found that eight weeks of full or half squats did not consistently change knee stability, and that powerlifters and weightlifters were no looser than controls ([Chandler et al., 1989](https://pubmed.ncbi.nlm.nih.gov/2733579/)).

Opinion did not settle in one direction. A 2001 biomechanics review still favored parallel squats over deep squats for healthy athletes because forces on the menisci and ligaments peak near full bending ([Escamilla, 2001](https://pubmed.ncbi.nlm.nih.gov/11194098/)), while a 2013 review argued that deep squats add no injury risk ([Hartmann et al., 2013](https://pubmed.ncbi.nlm.nih.gov/23821469/)). Since then, randomized training trials comparing depths, epidemiology linking hours of daily squatting to knee wear, work on squatting as "active rest", and studies of floor sitting-and-rising ability have reframed the question from whether deep squats are safe to how much, how loaded, and for whom.

  
## Expected Benefits

<!-- Search statement: On 2026-10-21 a dedicated search for the complete benefit profile was run on PubMed ("deep squat", "full squat", "squat depth", "range of motion" with resistance training, squatting and defecation, squatting and labor, sitting-rising test, squat breaks and glucose, squatting and hip osteoarthritis, resistance training and bone density) and with WebSearch on expert sources (Huberman Lab, FoundMyFitness, Lifespan.io, Peter Attia). The search specifically looked for studies of any design finding no effect or an opposite effect: the Pallarés 2021 meta-analysis (functional performance not significant), Kassiano 2023 (quadriceps growth similar with bottom-range partials), Hawari 2019 (no glucose change), the sham-controlled footstool trial NCT02877394, Lam 1993 (no reduction in pelvic-floor descent), Dudda 2011 (hip shape as an alternative explanation for low hip osteoarthritis), Jahn 2024 (no lower hip osteoarthritis odds with occupational squatting) and Dokmak 2020 (more caesarean sections). -->

### High 🟩 🟩 🟩

#### Greater lower-body strength and muscle growth than partial-depth squats ⚠️ Conflicted

Squatting to full depth builds more strength across joint angles, and more buttock and inner-thigh muscle, than half or quarter squats. Randomized trials in mostly young men from independent groups agree: Bloomquist in Copenhagen ([Bloomquist et al., 2013](https://pubmed.ncbi.nlm.nih.gov/23604798/)), Kubo in Tokyo ([Kubo et al., 2019](https://pubmed.ncbi.nlm.nih.gov/31230110/)), and Pallarés in Murcia ([Pallarés et al., 2020](https://pubmed.ncbi.nlm.nih.gov/31092132/)), pooled in a 16-study meta-analysis. Yet Kubo found similar front-thigh growth, and shallow training won for strength at its own angle. The net reading is an overall edge for full depth, weakest for front-thigh muscle.

**Magnitude:** Full versus partial range-of-motion training: standardized effect size (a unit-free difference; about 0.5 is moderate) 0.56 for strength and 0.88 for lower-limb muscle growth ([Pallarés et al., 2021](https://pubmed.ncbi.nlm.nih.gov/34170576/)); gluteus maximus volume grew 6.7% with full squats versus 2.2% with half squats (between-group p = 0.008; p is the probability of a difference this large arising by chance) ([Kubo et al., 2019](https://pubmed.ncbi.nlm.nih.gov/31230110/)).

#### Fewer instrument-assisted births when squatting in labor ⚠️ Conflicted ⭕️ Not Central to Health & Longevity

Across seven randomized trials, squatting during the pushing stage of labor reduced forceps and vacuum deliveries but increased caesarean sections, leaving spontaneous-birth rates similar ([Dokmak et al., 2020](https://pubmed.ncbi.nlm.nih.gov/32966958/)). Independent groups found fewer forceps births: Gardosi in Milton Keynes, UK ([Gardosi et al., 1989](https://pubmed.ncbi.nlm.nih.gov/2567873/)), and Nasir in Karachi ([Nasir et al., 2007](https://pubmed.ncbi.nlm.nih.gov/17319414/)). It bears on childbirth outcomes, not on health and longevity; three of the pooled trials were at low risk of bias. The net reading is no clear overall benefit.

**Magnitude:** Instrument-assisted delivery risk ratio (how many times as likely the outcome is) 0.60 (95% confidence interval [CI, the range likely to hold the true value] 0.45–0.81) and caesarean section risk ratio 2.26 (95% CI 1.07–4.80) versus lying positions ([Dokmak et al., 2020](https://pubmed.ncbi.nlm.nih.gov/32966958/)).

### Medium 🟩 🟩

No benefit reaches Medium: the remaining human data are indirect (chair-height squats, multi-lift programs, floor-transfer capacity, population comparisons) or contradicted by pooled or randomized evidence.

### Low 🟩

#### Jumping power and athletic performance ⚠️ Conflicted

Deep squat training raised jump height where quarter squats did not ([Hartmann et al., 2012](https://pubmed.ncbi.nlm.nih.gov/22344055/)), and full squats beat half squats for jump and sprint performance ([Pallarés et al., 2020](https://pubmed.ncbi.nlm.nih.gov/31092132/)). The pooled analysis did not confirm a significant advantage. The net reading is a likely but unconfirmed edge.

**Magnitude:** Functional performance, full versus partial range: standardized effect size 0.44 favoring full range, not statistically significant (p = 0.186) ([Pallarés et al., 2021](https://pubmed.ncbi.nlm.nih.gov/34170576/)).

#### Higher bone density in women with low bone mass

Eight months of supervised heavy back squats, deadlifts, overhead presses, and jumping chin-ups raised spine and hip bone density in postmenopausal women with low bone mass ([Watson et al., 2018](https://pubmed.ncbi.nlm.nih.gov/28975661/)). Indirect: squats were tested only together with other lifts, and squat depth was not reported.

**Magnitude:** Lumbar spine (lower back) bone density +2.9% versus −1.2% with low-intensity home exercise, and femoral neck (top of the thighbone) +0.3% versus −1.9% (between-group p < 0.001 and p = 0.004) ([Watson et al., 2018](https://pubmed.ncbi.nlm.nih.gov/28975661/)).

#### Lower after-meal blood sugar during long sitting ⚠️ Conflicted

Short squat breaks during prolonged sitting lowered after-meal glucose ([Gao et al., 2024](https://pubmed.ncbi.nlm.nih.gov/38629807/)) or insulin ([Gillen et al., 2021](https://pubmed.ncbi.nlm.nih.gov/33180640/)). Indirect: chair-height or unspecified-depth squats. A Glasgow trial lowered insulin but not glucose ([Hawari et al., 2019](https://pubmed.ncbi.nlm.nih.gov/30058957/)). The net reading is a small, short-term effect.

**Magnitude:** Glucose net incremental area (the after-meal rise in blood sugar summed over time) 7.9 versus 10.2 mmol/L·h with uninterrupted sitting, group 95% CIs 6.4–9.3 and 6.3–11.7 ([Gao et al., 2024](https://pubmed.ncbi.nlm.nih.gov/38629807/)).

#### Easier bowel emptying ⚠️ Conflicted

In 28 healthy volunteers, squatting cut emptying time and straining versus sitting ([Sikirov, 2003](https://pubmed.ncbi.nlm.nih.gov/12870773/)). A footstool trial against a lookalike 2-inch stool showed small, untested differences ([NCT02877394](https://clinicaltrials.gov/study/NCT02877394)), and squatting did not reduce pelvic-floor sagging on straining ([Lam et al., 1993](https://pubmed.ncbi.nlm.nih.gov/8311789/)). The net reading is plausible but unproven for constipation.

**Magnitude:** Footstool versus lookalike 2-inch stool: complete spontaneous bowel movements 1.6 versus 1.2 per week at 4 weeks (from 0.8 and 0.9 at baseline), not compared between groups ([NCT02877394](https://clinicaltrials.gov/study/NCT02877394)).

#### Floor sitting-and-rising ability tracks survival

In Brazilian cohorts from one group, led by Araújo, adults aged 46–80 who could sit on and rise from the floor without support lived longer ([Brito et al., 2014](https://pubmed.ncbi.nlm.nih.gov/23242910/); [Araújo et al., 2026](https://pubmed.ncbi.nlm.nih.gov/40569873/)). Indirect: the test measures capacity, not deep-squat practice, and the data are observational.

**Magnitude:** Lowest versus highest sitting-rising score: hazard ratio (HR, the relative death rate over follow-up) 5.44 (95% CI 3.1–9.5) for all-cause death ([Brito et al., 2014](https://pubmed.ncbi.nlm.nih.gov/23242910/)) and 6.05 (95% CI 2.29–20.94) for cardiovascular death ([Araújo et al., 2026](https://pubmed.ncbi.nlm.nih.gov/40569873/)).

#### Less hip osteoarthritis in habitually squatting populations ⚠️ Conflicted

Beijing elders, often daily squatters ([Zhang et al., 2004](https://pubmed.ncbi.nlm.nih.gov/15077301/)), had less hip osteoarthritis than white Americans ([Nevitt et al., 2002](https://pubmed.ncbi.nlm.nih.gov/12124860/)), possibly from hip shape ([Dudda et al., 2011](https://pubmed.ncbi.nlm.nih.gov/21647861/)). Indirect: a population comparison; occupational squatting showed no lower odds ([Jahn et al., 2024](https://pubmed.ncbi.nlm.nih.gov/38483209/)). The net reading is a clue, not proof.

**Magnitude:** Age-standardized prevalence ratio (how many times as common the condition is, after adjusting for age) 0.07–0.22 versus US white cohorts, with crude prevalence of 0.9% in Beijing women and 1.1% in Beijing men ([Nevitt et al., 2002](https://pubmed.ncbi.nlm.nih.gov/12124860/)); occupational squatting odds ratio (how many times higher the odds are) 1.1 (95% CI 0.9–1.4) for hip osteoarthritis versus less-exposed workers ([Jahn et al., 2024](https://pubmed.ncbi.nlm.nih.gov/38483209/)).

### Speculative 🟨

#### "Active rest" offsetting the harms of sitting

Resting squats demand more leg-muscle activity than chair sitting ([Raichlen et al., 2020](https://pubmed.ncbi.nlm.nih.gov/32152112/)). Whether this lowers sitting-related disease is untested; the basis is muscle-activity recording only.

#### Preserved hip, knee, and ankle mobility

Regular end-range practice is proposed to maintain the joint motion needed to sit on and rise from the floor. No controlled study has reported this; the basis is mechanistic and anecdotal.

  
## Benefit-Modifying Factors

- **Genetic variation:** No gene variant is known to change the strength, muscle, or mobility gains from deep squatting; gains from resistance training vary widely between individuals for reasons that remain largely unexplained.
- **Baseline glucose and body weight:** Squat breaks lowered after-meal glucose in men with overweight or obesity ([Gao et al., 2024](https://pubmed.ncbi.nlm.nih.gov/38629807/)) but only insulin in average-weight adults ([Gillen et al., 2021](https://pubmed.ncbi.nlm.nih.gov/33180640/)) and adults with obesity ([Hawari et al., 2019](https://pubmed.ncbi.nlm.nih.gov/30058957/)); baseline glucose is untested as a modifier.
- **Baseline ankle mobility:** Limited ankle dorsiflexion (upward bending of the foot) restricts depth; raising the heels more than 2.5 cm adds about 5° of ankle and knee motion ([Ghasemi et al., 2026](https://pubmed.ncbi.nlm.nih.gov/41612762/)).
- **Sex:** Women average about 6° more passive hip flexion than men ([Freiberger et al., 2024](https://pubmed.ncbi.nlm.nih.gov/37116553/)), easing depth; most depth-comparison trials enrolled only men, though one included 23 women ([Hartmann et al., 2012](https://pubmed.ncbi.nlm.nih.gov/22344055/)).
- **Pre-existing hip conditions:** People with femoroacetabular impingement (FAI, a ball-and-socket shape mismatch that pinches in deep bending) squat less deeply; depth improves after surgery ([Diamond et al., 2015](https://pubmed.ncbi.nlm.nih.gov/25246442/)).
- **Age:** Women averaging 65 years gained bone density and function from supervised heavy lifting ([Watson et al., 2018](https://pubmed.ncbi.nlm.nih.gov/28975661/)); the added benefit of protein supplements with training shrinks with age ([Morton et al., 2018](https://pubmed.ncbi.nlm.nih.gov/28698222/)).

  
## Potential Risks & Side Effects

<!-- Search statement: On 2026-10-21 a dedicated search for the complete side-effect profile was run. No prescribing information or drug-reference monograph exists for an exercise, so the closest reference sources were used: the American Heart Association 2023 and 2007 resistance-training statements (contraindications and safety), Harvard Health's "The lowdown on squats" (paywalled beyond the introduction) and general web references found with WebSearch. PubMed searches covered squatting with knee osteoarthritis, meniscal tears, peroneal nerve palsy, blood pressure, orthostatic hypotension, stroke, low back load and hip impingement; a later QA search for squatting and rhabdomyolysis added Yeon 2017 and Lin 2006. The search specifically looked for studies finding no excess risk or a lower risk: the Rojas-Jaramillo 2024 scoping review (no knee harm from deep-squat training), Chandler 1989 (no loss of knee stability), Pallarés 2020 (no pain increase with full squats) and LIFTMOR (one minor adverse event). -->

### High 🟥 🟥 🟥

No risk reaches High: the harms of deep squatting come from observational studies of workers, case series, and short laboratory blood-pressure measurements, not from trials by more than one independent group.

### Medium 🟥 🟥

#### Knee osteoarthritis with prolonged daily squatting ⚠️ Conflicted

Hours of daily squatting are linked to more knee cartilage wear, especially on the inner side in men. Beijing osteoarthritis odds trended upward with daily squatting time, short of significance ([Zhang et al., 2004](https://pubmed.ncbi.nlm.nih.gov/15077301/)); a meta-analysis linked occupational squatting to osteoarthritis ([Wang et al., 2020](https://pubmed.ncbi.nlm.nih.gov/32638548/)). A scoping review of lifters found no deep-squat knee harm in 13 of 15 studies; its full text, unlike its abstract (one case report), counts two suggesting harm ([Rojas-Jaramillo et al., 2024](https://pubmed.ncbi.nlm.nih.gov/39640505/)). The net reading is that risk tracks daily squatting hours, not training sets.

**Magnitude:** Odds ratio (OR) about 2.0 in men and 2.4 in women for the highest versus lowest daily-squatting category, trend p ≈ 0.07 ([Zhang et al., 2004](https://pubmed.ncbi.nlm.nih.gov/15077301/)); physically demanding work overall OR 1.52 (95% CI 1.37–1.69) versus sedentary work ([Wang et al., 2020](https://pubmed.ncbi.nlm.nih.gov/32638548/)). Absolute rates were not reported.

#### Meniscal tears with prolonged or repeated squatting

Deep knee bending compresses the back of the menisci (the knee's cartilage shock absorbers). Systematic reviews by two independent groups, Snoeker in Amsterdam ([Snoeker et al., 2013](https://pubmed.ncbi.nlm.nih.gov/23628788/)) and Bahns in Germany ([Bahns et al., 2021](https://pubmed.ncbi.nlm.nih.gov/34911509/)), link work-related squatting and kneeling to degenerative meniscal tears. Data are observational and come from manual workers with hours of daily exposure.

**Magnitude:** Occupational squatting effect estimate 2.01 (95% CI 1.34–3.03) for meniscal lesions versus unexposed workers ([Bahns et al., 2021](https://pubmed.ncbi.nlm.nih.gov/34911509/)); absolute rates were not reported.

### Low 🟥

#### Blood pressure surges while squatting

Holding a squat raised systolic pressure modestly in healthy adults and more in treated hypertensives ([Chakrabarti et al., 2002](https://pubmed.ncbi.nlm.nih.gov/11903123/)). Heavy barbell squats with breath-holding drove arterial pressure up to 345/245 mm Hg ([Palatini et al., 1989](https://pubmed.ncbi.nlm.nih.gov/2632751/)). Links to stroke rest on case observations.

**Magnitude:** Systolic rise of 8.1 mm Hg in healthy volunteers and 14.5 mm Hg in treated hypertensives on squatting versus lying; no control group ([Chakrabarti et al., 2002](https://pubmed.ncbi.nlm.nih.gov/11903123/)).

#### Dizziness or fainting on standing up from a squat

Rising from a squat briefly drops blood pressure (initial orthostatic hypotension), which can cause light-headedness or fainting. The drop was larger in type 2 diabetes ([Aiku et al., 2022](https://pubmed.ncbi.nlm.nih.gov/38798967/)); tensing leg muscles while rising lessened it ([Krediet et al., 2007](https://pubmed.ncbi.nlm.nih.gov/17561808/)).

**Magnitude:** Systolic fall on rising of 24.4 mm Hg in type 2 diabetes versus 9.8 mm Hg in adults without diabetes ([Aiku et al., 2022](https://pubmed.ncbi.nlm.nih.gov/38798967/)); fainting rates were not reported.

#### Foot drop from peroneal nerve compression

Squatting for hours compresses the peroneal nerve at the outer knee, causing foot drop (inability to lift the front of the foot). Case series of farmworkers report recovery in all or most patients with non-surgical care ([Sipahioğlu et al., 2015](https://pubmed.ncbi.nlm.nih.gov/25803253/); [Yildirim & Temel, 2023](https://pubmed.ncbi.nlm.nih.gov/36111735/)).

**Magnitude:** Onset after an average 6.8 hours of daily squatting and recovery in 7.4 weeks on average in 16 patients; no control group ([Sipahioğlu et al., 2015](https://pubmed.ncbi.nlm.nih.gov/25803253/)).

#### Muscle breakdown after high-volume squatting

Excessive squatting, especially without prior conditioning, can cause exertional rhabdomyolysis (muscle breakdown that can strain the kidneys). A Korean series described 10 squatting-induced cases ([Yeon et al., 2017](https://pubmed.ncbi.nlm.nih.gov/28181821/)). In a Taiwanese school endurance test, complete squats roughly tripled the odds ([Lin et al., 2006](https://pubmed.ncbi.nlm.nih.gov/16260462/)).

**Magnitude:** Among 157 high-school students after an endurance test, 43.3% developed exertional rhabdomyolysis (no unexposed comparison group); complete squats during the test carried an odds ratio of 3.21 (95% CI 1.12–10.00); kidney failure occurred in none ([Lin et al., 2006](https://pubmed.ncbi.nlm.nih.gov/16260462/)).

#### Knee pain from loaded deep-squat training ⚠️ Conflicted

The concern that loaded deep squats cause knee pain is not supported by a 10-week randomized trial: only half-squat training increased pain and stiffness, while full squats did not ([Pallarés et al., 2020](https://pubmed.ncbi.nlm.nih.gov/31092132/)). The net reading is that depth itself does not appear to add training pain.

**Magnitude:** Half-squat group: significant increases in pain and stiffness (standardized effect sizes 0.87–1.21); full-squat group: no significant increase; not compared between groups ([Pallarés et al., 2020](https://pubmed.ncbi.nlm.nih.gov/31092132/)).

### Speculative 🟨

#### Lower-back strain from pelvic tuck under load

At full depth the pelvis may tuck under, rounding the lower spine under load ("butt wink"), a proposed disc-strain mechanism. The basis is biomechanical reasoning only.

  
## Risk-Modifying Factors

- **Genetic variants:** The GDF5 rs143383 variant (GDF5 makes a growth factor that shapes joints) is linked to knee osteoarthritis in people of European, not Asian, ancestry ([Peng et al., 2020](https://pubmed.ncbi.nlm.nih.gov/32928309/)); its interaction with squatting is unstudied.
- **Baseline blood pressure and glucose:** Treated hypertension nearly doubled the pressure rise while squatting ([Chakrabarti et al., 2002](https://pubmed.ncbi.nlm.nih.gov/11903123/)); type 2 diabetes more than doubled the drop on rising ([Aiku et al., 2022](https://pubmed.ncbi.nlm.nih.gov/38798967/)).
- **Sex:** Being male is a risk factor for degenerative meniscal tears ([Snoeker et al., 2013](https://pubmed.ncbi.nlm.nih.gov/23628788/)); in Beijing, women showed a higher osteoarthritis odds ratio at the highest daily-squatting level ([Zhang et al., 2004](https://pubmed.ncbi.nlm.nih.gov/15077301/)).
- **Pre-existing joint disease:** Existing knee osteoarthritis, meniscal tears, or femoroacetabular impingement concentrate load where deep bending already hurts; impingement reduces achievable depth ([Diamond et al., 2015](https://pubmed.ncbi.nlm.nih.gov/25246442/)).
- **Age:** Age over 60 is a risk factor for degenerative meniscal tears ([Snoeker et al., 2013](https://pubmed.ncbi.nlm.nih.gov/23628788/)); older adults also have slower blood-pressure recovery on rising, raising fall risk.

  
## Key Interactions & Contraindications

<!-- Search statement: On 2026-10-21 PubMed was searched for squat* with "drug interaction" OR pharmacokinetics, and for squatting with antihypertensive, diabetes, orthostatic hypotension and supplement terms. No human interaction or pharmacokinetic study of deep squatting with any medication was found, so drug interactions below are inferred from mechanism and marked "(theoretical)". Human data exist for supplement co-use with squat or resistance training (creatine: Lanhers 2015; protein: Morton 2018; dietary nitrate: Tan 2023), and for blood-pressure and glucose responses to squatting in people with hypertension or diabetes (Chakrabarti 2002; Aiku 2022). -->

- **Blood-pressure-lowering drugs: alpha-blockers (vessel-relaxing drugs; doxazosin, tamsulosin), diuretics (drugs increasing urine output; hydrochlorothiazide), nitrates (vessel-widening heart drugs; nitroglycerin):** Caution (theoretical). They may deepen the pressure drop on rising, causing dizziness or fainting. Mitigation: slow rising and extended cool-downs.
- **PDE5 inhibitors (erectile-dysfunction drugs that widen blood vessels; sildenafil, tadalafil):** Caution (theoretical). Added vessel widening may enlarge the drop on standing from a squat, with light-headedness. Mitigation: no long deep squats in the hours after dosing.
- **Glucose-lowering drugs (insulin; sulfonylureas, insulin-releasing drugs such as glipizide):** Monitor (theoretical). Squat bouts lower glucose, risking hypoglycemia (low blood sugar); the American Heart Association (AHA; members earn no revenue from this advice) advises glucose checks before and after resistance sessions ([Paluch et al., 2024](https://pubmed.ncbi.nlm.nih.gov/38059362/)).
- **Anticoagulants (blood thinners; warfarin, apixaban):** Caution (theoretical). A strain or meniscal injury under load may bleed into the joint, causing swelling. Mitigation: moderate loads and controlled depth.
- **Sedative-hypnotics (calming and sleep-inducing drugs; zolpidem; benzodiazepines, anti-anxiety sedatives such as diazepam):** Caution (theoretical). Impaired balance and slower blood-pressure reflexes on rising from full depth raise fall risk. Mitigation: a hand support when standing.
- **Over-the-counter NSAIDs (nonsteroidal anti-inflammatory drugs; ibuprofen, naproxen):** Monitor (theoretical). Pain relief may mask an irritated knee or meniscus, allowing overload. Mitigation: no loaded deep squats while knee pain is masked by analgesics (pain-relieving drugs).
- **Over-the-counter sedating antihistamines (allergy drugs; diphenhydramine, doxylamine):** Caution (theoretical). Drowsiness and dizziness add to the pressure drop on rising, raising fall risk. Mitigation: slow rising with support.
- **Creatine supplement:** No harmful interaction; additive. In placebo-controlled trials creatine increased squat strength ([Lanhers et al., 2015](https://pubmed.ncbi.nlm.nih.gov/25946994/)). Body weight typically rises slightly and is monitored.
- **Protein supplements (whey, casein):** No harmful interaction; additive. Protein supplementation enlarged strength and muscle gains from resistance training, with no further lean-mass gain above about 1.6 g/kg/day total protein ([Morton et al., 2018](https://pubmed.ncbi.nlm.nih.gov/28698222/)).
- **Dietary nitrate (beetroot juice) and other blood-pressure-lowering supplements (garlic extract):** Caution (theoretical). Nitrate improved back-squat repetitions ([Tan et al., 2023](https://pubmed.ncbi.nlm.nih.gov/37299456/)), but its additive pressure-lowering effect may deepen the drop on rising, causing light-headedness. Mitigation: slow rising.
- **Glucose-lowering supplements (berberine, cinnamon extract):** Monitor (theoretical). Additive glucose lowering with squat breaks, mainly relevant alongside diabetes drugs; low blood sugar is the consequence. Mitigation: glucose checks before and after squat sessions.
- **Other interventions (sauna, hot baths):** Caution (theoretical). Heat widens blood vessels and may enlarge the pressure drop on rising from a squat afterwards. Mitigation: gradual rising after heat exposure.

**Populations who should avoid Deep Squat:**

- People with active proliferative or moderate-to-severe nonproliferative diabetic retinopathy (eye blood-vessel damage from diabetes) should avoid heavy loaded squats, which may trigger bleeding in the eye and retinal detachment ([Paluch et al., 2024](https://pubmed.ncbi.nlm.nih.gov/38059362/); AHA members earn no revenue from this advice)
- People with unstable coronary heart disease, uncontrolled heart-rhythm disorders, or severe, symptomatic aortic stenosis (narrowed heart valve) should avoid loaded squats, listed as absolute contraindications to resistance training by the AHA ([Williams et al., 2007](https://pubmed.ncbi.nlm.nih.gov/17638929/); AHA members earn no revenue from this advice)
- People with diabetes or with uncontrolled hypertension above 160/100 mm Hg need medical clearance first; the AHA lists these as relative contraindications, and hypertension above 180/110 mm Hg as an absolute one ([Williams et al., 2007](https://pubmed.ncbi.nlm.nih.gov/17638929/); AHA clinician members are paid for such clearance)
- People within six weeks of a posterior-approach hip replacement whose surgeon restricts hip bending beyond 90°, the restriction tested in a randomized trial that found no difference in dislocations ([Yadav et al., 2026](https://pubmed.ncbi.nlm.nih.gov/42055222/))
- People with an acute knee injury causing locking, giving way, or swelling, until assessed (theoretical: deep loaded bending compresses the menisci and may worsen a tear)
- People with numbness or foot drop after squatting, until it resolves; in a case series of 16 farmworkers, rest from squatting was part of the non-surgical care with which all recovered ([Sipahioğlu et al., 2015](https://pubmed.ncbi.nlm.nih.gov/25803253/))

  
## Risk Mitigation Strategies

Doses and timings below follow common practice unless cited.

- **Limited continuous squatting time:** Standing up every few minutes during long resting squats prevents peroneal nerve compression and reduces cumulative knee loading; palsy cases involved about 6.8 hours of daily squatting ([Sipahioğlu et al., 2015](https://pubmed.ncbi.nlm.nih.gov/25803253/)).
- **Slow rising with leg tensing:** Tensing leg and buttock muscles while standing up raised the lowest post-rise pressure by 13 mm Hg in healthy adults ([Krediet et al., 2007](https://pubmed.ncbi.nlm.nih.gov/17561808/)), reducing dizziness and fainting.
- **Standing blood-pressure checks:** A fall of 20/10 mm Hg within 3 minutes of standing defines orthostatic hypotension ([Freeman et al., 2011](https://pubmed.ncbi.nlm.nih.gov/21431947/); autonomic societies whose members diagnose it in paid practice); squatting is then paused pending medical review, preventing falls.
- **Moderate loads without long breath-holds:** Starting at 40–60% of one-repetition maximum (1RM, the heaviest load lifted once), per the AHA ([Paluch et al., 2024](https://pubmed.ncbi.nlm.nih.gov/38059362/); members earn no revenue from this advice), limits blood-pressure surges.
- **Capped daily squatting hours:** Knee osteoarthritis odds rose mainly at two or more hours of daily squatting ([Zhang et al., 2004](https://pubmed.ncbi.nlm.nih.gov/15077301/)); keeping resting squats to shorter bouts limits cumulative cartilage and meniscus load.
- **Gradual depth progression:** A box, a counter for support, or heel wedges over 2.5 cm ([Ghasemi et al., 2026](https://pubmed.ncbi.nlm.nih.gov/41612762/)) in place of forced depth reduce joint strain and pinching at the hip.
- **Supervised learning of loaded squats:** Supervised heavy training produced one minor back spasm in eight months ([Watson et al., 2018](https://pubmed.ncbi.nlm.nih.gov/28975661/)); coached technique limits lower-back strain from pelvic tucking.
- **Stopping on warning signs:** Knee locking, swelling, numbness, or foot drop end squatting until assessed; dizziness or chest pain need immediate medical evaluation per the AHA ([Paluch et al., 2024](https://pubmed.ncbi.nlm.nih.gov/38059362/); clinician members are paid for such evaluations), preventing harm progression.

  
## Therapeutic Protocol

Timing, cycling, titration steps, and other parameters below without a citation reflect common practice.

- **Loaded full-depth squat for strength:** Two sessions weekly for 10 weeks, loads progressing from 60% to 80% of 1RM ([Pallarés et al., 2020](https://pubmed.ncbi.nlm.nih.gov/31092132/)); full depth is the standard in Olympic-weightlifting coaching.
- **General resistance prescription:** The AHA describes 1–3 sets of 8–12 repetitions per exercise at least twice weekly, starting at 40–60% of 1RM ([Paluch et al., 2024](https://pubmed.ncbi.nlm.nih.gov/38059362/); AHA members earn no revenue from this advice).
- **Competing view on depth:** One biomechanics school favors stopping at thigh-parallel for healthy athletes ([Escamilla, 2001](https://pubmed.ncbi.nlm.nih.gov/11194098/)); another favors full depth with lighter loads rather than shallow squats with heavier loads ([Hartmann et al., 2013](https://pubmed.ncbi.nlm.nih.gov/23821469/)).
- **Resting deep squat for mobility:** 20 minutes daily, six days weekly for six weeks in a registered trial ([NCT06852677](https://clinicaltrials.gov/study/NCT06852677)); Kelly Starrett popularized daily floor sitting, including squatting positions ([Huberman Lab episode](https://www.hubermanlab.com/episode/dr-kelly-starrett-how-to-improve-your-mobility-posture-flexibility)).
- **Squat breaks during sitting:** Three minutes of squatting every 45 minutes ([Gao et al., 2024](https://pubmed.ncbi.nlm.nih.gov/38629807/)) or 15 chair squats every 30 minutes ([Gillen et al., 2021](https://pubmed.ncbi.nlm.nih.gov/33180640/)); Rhonda Patrick's FoundMyFitness promotes such breaks as "exercise snacks" ([FoundMyFitness topic page](https://www.foundmyfitness.com/topics/exercise-snacks)).
- **Time of day:** Morning and evening resistance training produced similar strength and muscle gains in a meta-analysis of 11 studies ([Grgic et al., 2019](https://pubmed.ncbi.nlm.nih.gov/30704301/)); squat breaks were tested around meals, when blood glucose rises.
- **Duration of effect:** As an exercise, not a compound, the deep squat has no half-life; the glucose-lowering effect of squat breaks is acute, measured on the day of the breaks rather than as a lasting change ([Gao et al., 2024](https://pubmed.ncbi.nlm.nih.gov/38629807/)).
- **Single versus split dosing:** Frequent short squat breaks lowered glucose more than one 30-minute walk of equal energy cost ([Gao et al., 2024](https://pubmed.ncbi.nlm.nih.gov/38629807/)); strength work is usually one session.
- **Genetics:** No gene variant, including joint-related variants such as GDF5, has been tested to guide squat depth, load, or volume.
- **Sex:** Women's greater average hip flexion ([Freiberger et al., 2024](https://pubmed.ncbi.nlm.nih.gov/37116553/)) may ease depth; trial protocols were mostly tested in men.
- **Age:** Women averaging 65 years safely trained five sets of five repetitions above 85% of 1RM under supervision ([Watson et al., 2018](https://pubmed.ncbi.nlm.nih.gov/28975661/)); older beginners typically start with bodyweight squats to a box.
- **Baseline markers:** Resting blood pressure, ankle mobility, and glucose status guide the choice between loaded and bodyweight squats, heel wedges, and squat breaks.
- **Pre-existing conditions:** Knee osteoarthritis, impingement, or a recent hip replacement typically limit depth to a pain-free range, with wider stance or box squats.

  
## Discontinuation & Cycling

- **Lifelong practice:** Deep squatting is meant as a lifelong habit; strength, muscle, and mobility gains fade when practice stops.
- **No withdrawal effects:** Stopping causes detraining rather than withdrawal; trained men who stopped training for 10 weeks declined on every strength and performance test ([Pallarés et al., 2020](https://pubmed.ncbi.nlm.nih.gov/31092132/)).
- **No tapering needed:** Stopping requires no taper; loads are typically reduced for a week or two before a competition or test.
- **Cycling through periodization:** The AHA describes periodized programs that vary intensity and volume to keep progressing and avoid injury ([Paluch et al., 2024](https://pubmed.ncbi.nlm.nih.gov/38059362/); members earn no revenue from this advice); resting squats need no cycling.
- **Restarting after a break:** After weeks off, depth and load are typically rebuilt over several sessions to limit soreness and joint irritation.

  
## Sourcing and Quality

Deep squatting requires no product, so purity and formulation do not apply; the considerations below concern equipment and instruction.

- **Footwear:** Flat, firm soles or weightlifting shoes with raised heels; heel elevation above 2.5 cm adds ankle and knee range ([Ghasemi et al., 2026](https://pubmed.ncbi.nlm.nih.gov/41612762/)). A non-compressible heel gives a more stable base than cushioned running soles.
- **Toilet footstools:** Footstools about 7 inches tall (e.g., Squatty Potty) approximate a squat on Western toilets; a trial against a lookalike 2-inch stool showed only small differences ([NCT02877394](https://clinicaltrials.gov/study/NCT02877394)).
- **Coaching:** For loaded squats, relevant credentials are a strength-coach certification (e.g., Certified Strength and Conditioning Specialist from the National Strength and Conditioning Association) or physical-therapy experience with barbell training.
- **Training equipment:** A power rack with adjustable safety bars allows failed repetitions to be set down safely; boxes or benches of graded height support depth progressions.

  
## Practical Considerations

- **Time to effect:** Strength and muscle differences between depths appeared within 10–12 weeks ([Bloomquist et al., 2013](https://pubmed.ncbi.nlm.nih.gov/23604798/); [Kubo et al., 2019](https://pubmed.ncbi.nlm.nih.gov/31230110/)); glucose effects of squat breaks appear the same day ([Gao et al., 2024](https://pubmed.ncbi.nlm.nih.gov/38629807/)); mobility timelines are unstudied.
- **Common pitfalls:** Forcing depth with heels lifting or knees collapsing inward, holding the breath on heavy sets, sitting in a squat for hours without breaks, and loading deep squats before range is comfortable.
- **Regulatory status:** As a bodyweight or barbell exercise, the deep squat involves no drug or device, so no regulatory approval applies; supervision and technique are left to individuals and coaches.
- **Cost and access:** Bodyweight squatting is free and needs no equipment; no insurer or health system has a financial incentive for or against it, so payer bias does not shape its evidence.

  
## Interaction with Foundational Habits

- **Sleep:** Indirect. Resistance training is associated with better sleep quality ([Paluch et al., 2024](https://pubmed.ncbi.nlm.nih.gov/38059362/); AHA members earn no revenue from this advice). Heavy squat sessions close to bedtime may delay sleep through arousal; resting squats in the evening carry no such concern.
- **Nutrition:** Potentiating. Adequate protein (lean-mass benefit plateaus near 1.6 g/kg/day) enlarges strength and muscle gains ([Morton et al., 2018](https://pubmed.ncbi.nlm.nih.gov/28698222/)); squat breaks after meals blunt glucose rises ([Gao et al., 2024](https://pubmed.ncbi.nlm.nih.gov/38629807/)). The deep squat depletes no nutrients.
- **Exercise:** Potentiating. Full-depth squats transfer to jumping better than quarter squats ([Hartmann et al., 2012](https://pubmed.ncbi.nlm.nih.gov/22344055/)). Heavy squats after long runs or intervals degrade technique, so they are typically placed first in a session.
- **Stress management:** Indirect. Resistance training is associated with fewer depressive and anxiety symptoms ([Paluch et al., 2024](https://pubmed.ncbi.nlm.nih.gov/38059362/); AHA members earn no revenue from this advice); quiet resting squats can pair with slow breathing, while heavy breath-held sets acutely raise blood pressure ([Palatini et al., 1989](https://pubmed.ncbi.nlm.nih.gov/2632751/)).

  
## Monitoring Protocol & Defining Success

Before starting, a baseline check records resting and standing blood pressure, ankle mobility with the weight-bearing lunge test (knee-to-wall distance), the sitting-rising test, and a simple strength measure such as five chair stands or a squat repetition maximum. People taking glucose-lowering drugs add a few days of glucose readings. Anyone with knee pain, locking, or a recent joint operation is assessed before loading full depth.

Ongoing monitoring follows a set cadence: blood pressure and dizziness at each of the first few loaded sessions, then every 3 months; ankle mobility, the sitting-rising test, and strength at 6 and 12 weeks, then every 6–12 months; glucose daily during the first two weeks of squat breaks for those on glucose-lowering drugs. Success means comfortable, pain-free depth, rising strength, and stable or improving floor transfers.

| Biomarker | Optimal Functional Range | Why Measure It? | Context/Notes |
|---|---|---|---|
| Resting blood pressure | Below 130/80 mm Hg (2017 ACC/AHA guideline target) | Safety check: uncontrolled values change whether heavy squats are used | Source: [Whelton et al., 2018](https://pubmed.ncbi.nlm.nih.gov/29133356/) (American College of Cardiology and AHA; members include clinicians paid to treat hypertension). No separate conventional reference range exists; the guideline's "normal" category is below 120/80 mm Hg. Seated, after 5 minutes' rest, before exercise |
| Standing blood-pressure change | Fall smaller than 20 mm Hg systolic and 10 mm Hg diastolic within 3 minutes (Freeman et al., 2011 consensus definition) | Safety check: a larger fall prompts stopping and medical review | Source: [Freeman et al., 2011](https://pubmed.ncbi.nlm.nih.gov/21431947/) (consensus of autonomic societies whose members diagnose this condition in paid practice). No separate conventional reference range exists. Pair with a squat-to-stand reading; worse in diabetes |
| Post-meal blood glucose (continuous glucose monitor) | No established target; track change in the individual's own after-meal curves on matched meals with and without squat breaks | Expected to change: squat breaks lower after-meal glucose | No sourced optimal range or conventional reference range for after-meal readings applies here; safety check for hypoglycemia when on insulin or sulfonylureas |
| Weight-bearing lunge test (ankle dorsiflexion) | No established target; track change from the individual's own baseline | Expected to change: practice may increase depth-limiting ankle range | Knee-to-wall distance in centimeters; test both sides, barefoot, same time of day |
| Sitting-rising test score (0–10) | 8–10, the highest-survival category ([Brito et al., 2014](https://pubmed.ncbi.nlm.nih.gov/23242910/)) | Expected to change: practice targets floor-transfer capacity | Source: Brito et al., 2014. No conventional reference range exists. One point lost per hand or knee support |

Qualitative markers:

- Comfort and time spent in a resting squat without pain
- Ease of getting down to and up from the floor
- Knee comfort the day after loaded sessions (no swelling or locking)
- Absence of dizziness when standing up
- Absence of numbness or foot weakness after long squats
- Ease of bowel emptying, for those using squatting or a footstool

  
## Emerging Research

- **Squat training for pre-sarcopenia (early age-related muscle loss) ([NCT07726758](https://clinicaltrials.gov/study/NCT07726758)):** Recruiting; 80 older adults, 12 weeks of squat exercise versus usual activity; primary outcomes are a walking, balance and chair-rise battery and body composition; completion 2028. Positive results would strengthen functional benefits in older adults; null results would confine benefits to strength.
- **Deep squat or cross-legged sitting for low back pain ([NCT06852677](https://clinicaltrials.gov/study/NCT06852677)):** Randomized, 36 adults, 20 minutes daily for six weeks; completed September 2025, no results posted. Positive results would give the first controlled support for resting-squat mobility and strengthen the bowel benefit; null results would keep mobility speculative and weaken the bowel benefit.
- **Squatting footstool for constipation ([NCT02877394](https://clinicaltrials.gov/study/NCT02877394)):** Compared with a lookalike 2-inch stool, 107 enrolled; active, not recruiting. Posted results show 1.6 versus 1.2 complete bowel movements weekly, not formally compared. A positive full analysis would raise the bowel benefit; a null one would weaken it further.
- **Heel-elevated versus flat squats ([NCT07700641](https://clinicaltrials.gov/study/NCT07700641)):** Randomized, 42 active women, eight weeks of bodyweight squats; completed July 2026, no results posted. Results would show whether heel wedges, used to reach depth, change thigh-muscle growth and strength.
- **Isometric (held without movement) wall squats for hypertension ([NCT07868822](https://clinicaltrials.gov/study/NCT07868822)):** Recruiting, 100 adults; completion 2029. It tests partial-depth holds; positive results would support squat-based blood-pressure lowering but not deep squats specifically, while null results would remove that indirect support.
- **Long-muscle-length training:** Reviews suggest training at longer muscle lengths may grow muscle more, but evidence is mixed ([Wolf et al., 2026](https://pubmed.ncbi.nlm.nih.gov/41646176/); [Kassiano et al., 2023](https://pubmed.ncbi.nlm.nih.gov/36662126/)); direct trials could strengthen the depth rationale or show partial repetitions near the bottom suffice.
- **Long-term knee safety:** Deep-squat training studies follow lifters only for weeks to months ([Rojas-Jaramillo et al., 2024](https://pubmed.ncbi.nlm.nih.gov/39640505/)), while occupational data show knee harm with hours of daily squatting ([Bahns et al., 2021](https://pubmed.ncbi.nlm.nih.gov/34911509/)); multi-year imaging could confirm or weaken the safety case.

  
## Conclusion

The deep squat is both a resting posture and a strength exercise taken through the full bend of the hips, knees, and ankles. For health-focused adults willing to practice it, the clearest benefit is that full-depth squatting builds more leg strength and more buttock and inner-thigh muscle than shallow squats, a finding repeated by independent research teams.

Other benefits are weaker. Short squat breaks during long sitting may blunt blood-sugar rises after meals, heavy multi-lift programs that include squats raised bone density, and squatting may ease bowel emptying, but these rest on indirect or conflicting evidence. People who can get down to the floor and back up without help live longer, yet this reflects overall fitness; practicing the squat has not been shown to cause it.

The main risks come from dose. Many hours of daily squatting, mostly in manual work, are tied to knee cartilage wear and torn knee cartilage pads, while brief training sets have not shown this harm in short studies. Blood pressure rises during squats and can dip on standing, which matters most for people with heart disease, diabetes, or blood-pressure medication.

The evidence base is small, mostly short-term, and for harms rests largely on watching groups of people rather than on experiments. No company sells the deep squat, but the heart association's call for medical clearance, the blood-pressure targets, and the definition of dizziness on standing come from groups whose members are paid to examine, diagnose, and treat those conditions.
