Bodyweight Squats
The bodyweight squat is an unloaded squat where you lower your hips until your thighs are at least parallel to the floor and stand back up. It trains the quadriceps and glutes, and is the standard starting point for learning squat technique before adding load. Usually trained for 3 sets of 15–25 reps.
Also known as: Air squat, Free squat, Unweighted squat

What muscles does the bodyweight squats work?
Primary movers
- Quadriceps
- Gluteus maximus
Assisting muscles
- Adductor magnus
- Hamstrings
- Calves
- Abdominals
The bodyweight squat trains the same muscles as a loaded squat — quads extending the knee, glutes and adductors extending the hip — just with a much smaller load. That makes it useful for learning the pattern and for higher-rep conditioning work rather than for building maximum strength.
Because there is no bar on your back, your torso stays much more upright and your spinal erectors work far less. That is what makes it accessible: the limiting factor is your legs and your mobility, not your ability to brace a load.
The trade-off is that most people outgrow it quickly for strength purposes. Once you can do 25 clean reps, additional reps mostly build endurance. Progressing means adding load or shifting to a harder single-leg variation.
Ankle and hip mobility become obvious here, without a bar hiding them. If your heels lift or your torso pitches forward on an unloaded squat, that restriction will only get worse under a barbell — this is the place to find and fix it.
How to do the bodyweight squats
Setup
- 1
Stand with your feet roughly shoulder-width apart, toes turned out 15–30 degrees.
- 2
Distribute your weight evenly across your whole foot.
- 3
Stand tall with your chest up and your ribs down over your pelvis.
- 4
Hold your arms out in front of you for balance, or clasp your hands at your chest.
- 5
Brace your abs lightly — you do not need a maximal brace without load.
Execution
- 1
Begin by breaking at the hips and knees at the same time, sitting down rather than just back.
- 2
Push your knees out so they track over your toes as you descend.
- 3
Keep your torso as upright as your mobility allows and your heels flat on the floor.
- 4
Lower until your thighs are at least parallel to the floor, or deeper if you can without your lower back rounding.
- 5
Drive up through your whole foot, keeping your knees pushed out.
- 6
Stand tall at the top, squeezing your glutes without leaning back.
Common bodyweight squats mistakes
Knees caving inward
The knees drift toward each other on the way up. Usually weak or under-recruited glutes, sometimes just a habit that will follow you under a barbell.
The fix: Actively push the knees out over the toes throughout. Looping a light band above the knees gives useful feedback because it forces you to resist inward pull.
Excessive forward lean
The chest drops toward the floor and the squat becomes a hinge. Typically limited ankle mobility, occasionally a stance that is too narrow.
The fix: Widen your stance slightly and turn the toes out more. Try squatting with your heels on a small plate — if the lean disappears, ankle mobility is the culprit.
Rising onto the toes
The heels lift at the bottom, which shifts you forward and puts the knees in a poor position.
The fix: Almost always ankle dorsiflexion. Keep depth to where your heels stay planted and work on ankle mobility between sessions rather than forcing depth now.
Not reaching adequate depth
Stopping well above parallel. Partial squats train the quads through their easiest range and build very little.
The fix: Squat to a box or bench set at a depth you can reach cleanly, then lower the target over time as your mobility improves.
How many sets and reps?
| Goal | Sets | Reps | Load | Rest |
|---|---|---|---|---|
| Technique practice | 2–3 | 10–15 | Bodyweight, well short of failure | 60 s |
| Muscular endurance | 3 | 20–30 | Bodyweight, 1–2 RIR | 60–90 s |
| Warm-up | 1–2 | 10–15 | Bodyweight | — |
Bodyweight squats are a movement-quality tool and a warm-up, not a long-term muscle builder for most people. They tolerate daily practice at low volume, which makes them ideal for grooving the pattern. Once 25 clean reps is comfortable, progress to goblet squats or Bulgarian split squats rather than chasing 50-rep sets.
Bodyweight Squats variations and alternatives
Box Squat
EasierSquatting to a box fixes your depth and removes any uncertainty about how far to go. The best regression if depth or confidence is the problem.
Goblet Squat
HarderHolding a dumbbell or kettlebell at the chest adds load and actually improves torso position by counterbalancing you. The natural next step.
Jump Squat
HarderAdds an explosive element and considerably more force. Good for power development, but land softly through the whole foot.
Pistol Squat
HarderA single-leg squat to full depth. Demands substantial strength, balance and ankle mobility — a long-term skill goal rather than a next step.
Barbell Back Squat
HarderThe loaded version. Once the bodyweight pattern is clean, this is where meaningful strength and size progress comes from.
Frequently asked questions
Do bodyweight squats build muscle?
For a complete beginner, yes — early on, almost any challenging stimulus produces adaptation. But bodyweight is a fixed load, and once you can perform 20–25 clean reps the sets become endurance work rather than growth work. To keep building muscle you need to add load or move to a harder single-leg variation.
How many bodyweight squats should I do?
For technique practice, 2–3 sets of 10–15 with perfect form beats high-rep sets. For conditioning, 3 sets of 20–30. Chasing very high rep counts mostly builds tolerance to discomfort rather than muscle or strength.
Why do my heels come up when I squat?
Almost always limited ankle dorsiflexion — your shin cannot travel far enough forward over your foot, so your body compensates by lifting the heel. Test it by squatting with your heels on a small plate or in shoes with a raised heel. If the problem disappears, work on ankle mobility and squat to a depth where your heels stay down in the meantime.
Are bodyweight squats enough for leg day?
Not for an intermediate lifter. They cannot provide enough mechanical tension to keep driving growth once you are past the beginner phase. They work well as a warm-up, a movement-quality drill, or as part of a home workout combined with harder single-leg variations like split squats and step-ups.
How deep should a bodyweight squat be?
At least until your thighs are parallel to the floor, and deeper if you can get there with your heels down and your lower back neutral. Without a load on your back, most people can and should squat deeper than they do — full depth trains the quads and glutes through a longer range.
