The squat is one of the most effective exercises you can do, and one of the most commonly done wrong. Here is what a squat is, exactly how to do it with good form, the muscles it works, and the variations worth learning.
Quick answer: A squat is a lower-body strength exercise where you bend your knees and hips to lower your body, then stand back up. It mainly works the quads, glutes, and hamstrings, plus the core. To squat correctly: stand shoulder-width apart, keep your chest up and back neutral, push your hips back and down, keep your knees tracking over your toes, and drive up through your heels.
Muscles a Squat Works
|
Muscle group |
Role in the squat |
|
Quadriceps (front thighs) |
Extend the knees, main mover |
|
Glutes (buttocks) |
Extend the hips, power the stand-up |
|
Hamstrings (back thighs) |
Support the hips and knees |
|
Core (abs and lower back) |
Stabilize the spine |
|
Calves |
Help with balance and drive |
Because it trains so many muscles at once, the squat builds strength, tones the lower body, and burns more calories than isolation moves. Learn more about the muscles in understanding the glute muscles.

How to Do a Bodyweight Squat Correctly
- Stand with feet about shoulder-width apart, toes pointed slightly out.
- Brace your core and keep your chest up, spine neutral.
- Hinge and bend: push your hips back and bend your knees, as if sitting into a chair.
- Lower until your thighs are about parallel to the floor, or as far as you can with good form.
- Keep your knees tracking in line with your toes, not caving inward.
- Drive up through your heels to stand, squeezing your glutes at the top.
Keep your weight in your heels and mid-foot, and do not let your heels lift.
Common Squat Mistakes (and Fixes)
- Knees caving inward: push your knees out to track over your toes.
- Heels lifting: keep weight in your heels; widen your stance if needed.
- Rounding the back: brace your core and keep your chest up.
- Not going deep enough: aim for thighs parallel, within your mobility.
- Leaning too far forward: sit your hips back rather than tipping over your toes.
