There is no single correct stance or depth for everyone. First find the version you can balance and control, then change stance width or heel height for a clear reason.

What bodyweight squats train
A squat turns sitting down and standing up into a repeatable lower-body strength movement. The hips and knees bend together on the way down and extend together on the way up; the exercise catalog therefore lists the quadriceps and glutes as primary, with the hamstrings assisting.
How to do a bodyweight squat
Use a natural, stable stance, usually around shoulder width, with the toes allowed to turn out slightly. Press the base of the big toe, base of the little toe, and heel into the floor.
Brace your trunk and reach your arms forward. Move the hips back and down as the knees bend, keeping each knee pointed in the same direction as its toes.
Descend only as far as your feet stay planted and the movement stays controlled. Your depth does not need to match anyone else's.
Drive the whole foot down to stand. Let the hips and knees straighten together, then finish tall without snapping the knees backward.
Effort, joint motion, and a mild stretch can be normal; sharp pain, pinching, or discomfort that builds rep by rep is not a depth target to push through. Shorten the range or use support, and have persistent pain assessed by a qualified professional.
Make it easier or harder
Learn control
Touch a chair behind you, then stand
The chair marks depth; do not sit and relax.
Keep balance
Use fingertips on a fixed counter
Use only enough help to stay steady, then reduce it.
Add challenge
Add range, then a slower descent or pause
Change one variable while the feet and knee path stay controlled.
Change stance
Use a sumo squat
For trying a wider stance, not as an automatic upgrade.
Change the ankle setup
Elevate the heels on a solid wedge
Useful when the ankle limits depth; never use loose objects.
Deeper is not automatically better for everyone, but controlled range is worth developing. In a 10-week loaded-squat trial of only 17 men, full and half squats produced similar quadriceps growth, while full squats produced more gluteus maximus and adductor growth. [1] That supports gradually expanding usable range; it does not prescribe one required depth or prove the same outcome for bodyweight squats.
Sumo squat: widen the stance
The sumo squat changes one main variable: the feet move wider than in your standard squat and the toes usually turn out farther. Do not jump straight to the widest stance possible. Start just outside shoulder width and keep the stance where the hips can descend, the feet stay planted, and the knees follow the toes.
A wider stance changes the mechanics, but there is no single optimal width. A study with a 70-lifter observational experiment and a 20-lifter repeated-measures experiment found higher modeled quadriceps forces in the narrow condition and higher posterior-chain forces in the wide condition during squats at 70% 1RM. [2] Those are acute, loaded-squat model results—not a promise that bodyweight sumo squats produce more muscle growth.
Heel-elevated deep squat: change the ankle setup
Place both heels on one solid, nonslip wedge while the forefeet stay on the floor. Keep roughly your natural squat stance, allow the knees to travel in the direction of the toes, and stop where the pelvis and trunk remain controlled. Do not use stacked books, loose plates, or supports of different heights.
Heel elevation does not “fix” the ankles; it changes the task in that moment. A 2026 meta-analysis of 14 studies and 177 healthy adults found that elevating the heels increased knee range of motion by about 4.94° on average, without a significant change in hip or trunk range. [3] It can make deep knee flexion easier to access, but that does not make it automatically safer or necessary for everyone.
Common mistakes
Copying someone else's stance width and toe angle instead of finding your stable position.
Thinking “heels only” until the toes and forefoot lift. Keep pressure through the whole foot.
Letting a knee suddenly collapse inward away from the direction of the toes; shorten the range or regress.
Chasing depth after balance, foot contact, or bottom-position control has gone.
Elevating the heels on something that can slide, collapse, or leave one side higher.
Build a squat interval
Frequently asked questions
What muscles do bodyweight squats work?
Bodyweight squats primarily train the quadriceps and glutes, with the hamstrings assisting. The hips and knees bend together on the way down and extend together as you stand.
How deep should I squat?
Use the deepest range where your whole foot stays planted, your knees keep tracking with your toes, and your pelvis and trunk remain controlled. Depth can improve gradually; it does not need to match another person's squat.
Can my knees go past my toes when I squat?
Yes. Knee travel past the toes can be a normal part of a deep squat. Keep the whole foot planted, let each knee move in the same direction as its toes, and use a range that stays controlled and does not provoke pain.
Are sumo squats better than regular squats?
No version is universally better. A sumo squat uses a wider stance and changes the mechanical demands, but it is an option rather than an upgrade. Use the stance in which your feet stay planted and your knees can follow your toes.
Why elevate the heels for a squat?
A solid heel wedge changes the ankle setup and can make deeper knee flexion easier to access. It does not fix ankle mobility or make the squat automatically safer, and the support must be stable, nonslip, and equal under both heels.
