The air squat is a body-weight strength exercise for the thighs, training the quadriceps, glutes, and hamstrings without any equipment. It builds lower-body strength, hip and knee mobility, and movement skill, making it a staple warm-up and a foundation for loaded squats.
How to do the Air Squat
- 1Stand with your feet about shoulder-width apart, toes turned slightly outward and arms relaxed at your sides.
- 2Brace your core, keep your chest up, and shift your weight back into your heels and mid-foot.
- 3Push your hips back and down as if sitting into a chair, bending your knees to begin the descent.
- 4Lower until your thighs are at least parallel to the floor, raising your arms forward for balance as you sink.
- 5Keep your knees tracking in line with your toes and your heels flat on the ground throughout.
- 6Drive through your whole foot to stand back up, extending your hips and knees until you are fully upright.
- 7Squeeze your glutes at the top, then repeat for your target number of reps.
Form tips
- Keep your weight balanced over your mid-foot and heels rather than letting it drift onto your toes.
- Maintain a neutral spine with your chest up; avoid rounding your lower back at the bottom.
- Control the descent for a beat instead of dropping fast, then stand up with intent.
- Aim for at least thigh-parallel depth, going deeper only as far as you can keep your heels down and back flat.
Common mistakes
- Letting your knees cave inward, which stresses the knee joint and wastes power from the glutes.
- Lifting your heels and shifting onto your toes, which makes the squat unstable and reduces glute and hamstring involvement.
- Rounding your lower back at the bottom, which puts the spine at risk under repeated reps.
- Cutting the depth short by stopping well above parallel, which limits the work your thighs and hips do.
Frequently asked questions
What muscles does the air squat work?
It works the muscles of the thighs and hips — mainly the quadriceps, glutes, and hamstrings — using only your body weight. Your core also works to keep your torso upright.
How wide should my stance be?
About shoulder-width with your toes turned slightly outward is a solid default. Find the width that lets you reach parallel depth with your heels flat and knees tracking over your toes.
Is the air squat good for beginners?
Yes. Because it uses only body weight, it is one of the best ways for beginners to learn squat mechanics, build leg strength, and prepare for loaded variations later.
How many reps should I do?
For body-weight squats, sets of 15–25 reps work well for endurance and conditioning. Lower the reps and add tempo or pauses if you want more of a strength challenge.
