Why bodyweight squats work
A squat is a hip-and-knee hinge that mimics sitting down and standing back up — arguably the single most-used movement pattern in daily life, from getting off a couch to picking something off the floor. Training it directly, through a full range of motion, builds the leg and glute strength that pattern depends on, and reinforces the joint control needed to do it safely under load later.
How to do bodyweight squats
- Stand with feet about shoulder-width apart, toes turned slightly out.
- Brace your core and keep your chest up.
- Push your hips back and bend your knees as if sitting into a chair.
- Lower until your thighs are about parallel to the floor (go as deep as you comfortably can).
- Drive through your heels to stand back up, squeezing your glutes at the top.
Form tips
- Keep your weight in your heels and mid-foot, not your toes.
- Let your knees track in line with your toes.
- Keep your chest proud and back flat throughout.
Depth, knees, and the myths around both
Two pieces of squat folklore cause more confusion than everything else combined, and both are wrong.
The first is that your knees must never travel past your toes. In reality, allowing the knee to move forward is normal and necessary for anyone with average or long femurs to reach depth while staying balanced — walking down stairs involves considerably more forward knee travel than a squat does. Rigidly forcing the shins vertical simply transfers the load to the lower back. What matters is that the knees track in line with the toes rather than collapsing inward.
The second is that deep squatting damages the knees. For most people, squatting through a controlled full range strengthens the muscles, tendons and connective tissue around the joint. Depth that hurts is worth investigating; depth in itself is not the problem. Squat as low as you can while keeping your heels down and your lower back from tucking under.
That tuck — sometimes called butt wink — is your genuine depth limit for now, and it is usually an ankle mobility restriction rather than anything about your hips. If your heels lift or your pelvis rounds under, stop just above that point and work on ankle mobility separately. Squatting with your heels slightly elevated on small plates is a legitimate way to train fuller depth while that improves.
Sets and reps
Beginners: 3 sets of 10–15 reps. Increase reps, slow the tempo, or progress to single-leg variations as you get stronger.
Programming it into your week
Squats belong early in a lower-body session while you are fresh and your technique holds. Three sets of ten to fifteen, two or three times a week, is a sound starting dose. If you are also running or cycling hard, keep the squat volume moderate — the legs only have so much recovery to distribute.
How to progress
Box squats first if depth or confidence is an issue — sitting to a chair and standing teaches the pattern safely. From full bodyweight squats, the useful next steps are tempo (three seconds down), pause squats (two seconds at the bottom), then goblet squats with a weight, then single-leg work. Most people can move from box squats to comfortable full-depth bodyweight squats within six to eight weeks.
Variations & progressions
- Easier: box squats (sit to a chair and stand).
- Harder: pause squats, tempo squats, or jump squats.
- Advanced: pistol (single-leg) squats.
How it compares
Against the leg press, the squat asks your trunk to stabilise the load rather than doing that job for you, which is most of its value. Against lunges, it loads both legs simultaneously so you can handle more total work, but it hides side-to-side imbalances that a single-leg movement exposes.
Equipment
None. A chair or box is useful for learning depth; a kettlebell or dumbbell opens up goblet squats when bodyweight stops being challenging.
