How to Do a Squat: Bodyweight Form, Depth and Fixes

How do you do a squat?

1. Stand with your feet about shoulder width apart. Adjust a little wider or narrower until you can lower comfortably between your hips. Turn your toes out slightly; 10–30 degrees is a common starting range, not a position you must force.
2. Reach your arms forward for balance. Keep your gaze ahead and your ribs over your pelvis. Take a breath before you move.
3. Bend at your hips and knees together. Think of sitting down between your legs rather than sending your hips as far back as possible.
4. Let your knees follow the line of your toes. They can move forward. Keep the heel, base of the big toe, and base of the little toe on the floor.
5. Lower as far as you can while your heels stay down and your back does not round at the bottom. Stop a little above the point where either changes.
6. Push the floor away to stand. Let your hips and shoulders rise together, straighten your knees and hips, and reset before the next rep.

Use a slow first rep to check your stance. If it makes you twist, move your feet a little and try again. The bodyweight squat exercise page has a shorter movement reference.

An air squat is a bodyweight squat: you squat without added weight. It does not mean that you should jump or move quickly.

How deep should you squat?

Your working depth is the lowest point you can reach while keeping your heels down, knees following your toes, and back from rounding. For one person that may be above parallel today; another may sit lower. Mark a repeatable depth with a stable box or a side-view video, then use the same standard on every counted rep. Do not bounce off a box.

Test depth with three slow, unloaded reps. Lower for about three seconds, pause briefly at the lowest clean point, and stand. If your heels lift on rep two, shorten the range until all three match. If you can go lower only by folding your torso or tucking your pelvis hard under you, the extra depth is not yet useful for these working sets.

A deep squat is not automatically a dangerous squat. Hartmann and colleagues reviewed squat depth and concluded that concerns about deep squats harming passive knee tissues are unfounded when technique is learned and loading progresses gradually. That review is not a reason to force your own deepest position on the first day. Earn more range by controlling it, and keep the same standard as repetitions become harder.

If you are unsure whether a shallow rep is intentional, lightly touch a stable box and stand without relaxing into it. Lower the target only when your shape holds. The calisthenics hub places this leg pattern before harder single-leg skills.

Can your knees go past your toes?

Yes. When you squat, your knees can move forward beyond your toes while still following their line. Do not turn a possible outcome into a target: focus on balance over the whole foot and a controlled descent.

Fry and colleagues found that restricting forward knee travel in a barbell squat reduced knee torque but increased torque at the hips and lower back. That experiment used a loaded squat, so it does not supply a safe angle or depth for every bodyweight rep. It does show why a blanket rule to keep the knees behind the toes shifts the task elsewhere rather than simply removing load.

Watch the direction as well as the distance. If your knees collapse inward, slow down and shorten the range. If keeping them back makes your heels lift or torso fold, allow more forward movement and retest your balance.

Are squats bad for your knees?

Squatting is a knee-bending task, so the knees do work, and for healthy knees that work is how they get stronger. The Hartmann review in the depth section is about well-learned technique and gradual progression; it does not mean a squat that hurts should be repeated at the same depth.

Separate muscle effort from pain in a joint. If your thighs work hard but your movement stays controlled, finish the planned clean reps. If you feel sharp or joint pain, stop that set. On another attempt, use a shorter comfortable range or a box and check whether the symptom changes. Do not push through pain to meet a depth or rep target. If sharp pain persists, see a physiotherapist or doctor before training the movement again.

Which squat variation should you start with?

Do the three-rep depth test, then choose the hardest version you can repeat without lifting your heels, rounding your back, or shifting to one side. Use a stable chair or box for sit-to-stands. For support, hold a fixed doorframe or sturdy post that will not move when you lean on it. Keep the support light enough that your legs still do the work.

Legs are strong relative to your body weight, so squat rep targets sit higher than push-up targets. The numbers below are coaching starting targets, not study results. Rest about 90 seconds to two minutes between sets. Use the exit rule only after every set meets the same movement standard in two sessions. If you get 15, 15, 11 on a 10–15 target, stay on that rung.

You need not use every rung. A low box may be harder than a lightly supported squat; choose the version with the cleanest range. If unsupported reps tip you back, use light support and gradually reduce hand help. The supported split squat exercise page shows the staggered stance. For the final rung, follow the pistol squat progression.

When a new rung drops below the bottom of its range, return to the previous one. Record the version, support, and depth; eight shallow reps and eight controlled reps are different results.

What common squat faults should you fix?

• Heels lift: Try a slightly wider stance or let your knees travel farther forward while keeping the whole foot down. Shorten depth to the last point where your heels stay planted. Use light support if you still tip back.
• Knees cave in: Slow the descent and aim each knee along its matching toes. Stop at the depth where you can keep that direction. Move to a box or supported squat if the last reps collapse.
• Back rounds at the bottom: End the rep just before your pelvis tucks hard under and your lower back changes shape. Pause there, stand, and build repeatable control before lowering farther.
• Torso folds forward: Bring your arms forward, allow hips and knees to bend together, and check that your weight is spread across the foot. Use a higher box if you still have to pitch forward to stand.
• You shift to one side: Film from the front or use a mirror to see when the shift begins. Reduce depth or add light hand support until both legs share the movement. Count only reps that look even.

Fix the first fault that appears, then retest. Change one thing at a time so you can tell what helped.

How many sets and reps should you do?

For a first squat practice, try three sets in the range of your rung (10–15 for the bodyweight squat) on two or three nonconsecutive days a week. Rest about 90 seconds to two minutes between sets. ACSM's resistance-training position stand includes two to three training days per week for novices and gradual progression. The exact three-set range here is a practical coaching choice; the paper does not prescribe this particular squat ladder.

Start each session with two or three easy practice reps at your chosen depth. Then do the working sets. Stop a set at the last rep that keeps the heel, knee direction, and back position you chose. A set of 15, 13, 11 is useful information; do not turn it into 15, 15, 15 by counting shorter reps. Repeat the same rung next session and try to improve one clean rep.

For a four-week starting pattern, use week one to find your stance and rung, and keep every set near the bottom of its range. In week two, add reps within the range only where form holds. In weeks three and four, continue at the earned rung; move up only after all three sets reach the top of the range in two sessions. If you miss a session, resume your last rung instead of doubling the next day's work. The exit rule matters more than the calendar.

For a separate discussion of daily totals, read how many squats a day. The quad exercise directory shows other leg movements.

When should you add weight to a squat?

Add weight after you can repeat your chosen bodyweight depth and balance across all working sets. A goblet squat, with a weight held close to the chest, is one possible next step. Start with a load that still lets your feet stay down and your hips and shoulders rise together. If holding weight changes the movement, go lighter or return to bodyweight practice.

The loaded-squat form checklist covers adding weight. You can also practise a pause, tempo, or split squat without loading.

When should you stop a squat session?

Stop a set when you cannot keep the same depth, your heels rise, your back rounds, or you repeatedly shift sideways. Rest, then try an easier variation or fewer clean reps. Stop the session for sharp or joint pain rather than testing whether it disappears under fatigue. Ordinary thigh effort is different from joint pain.

If one session feels unusually hard, aim for the bottom of the range or use the previous rung. Log that change instead of forcing the planned target. On the next visit, start from the version that gave you reliable reps, then retest the harder one only if your first set is steady.

How do you track squat progress in Trainer?

Logging is free in Trainer, and every set arrives pre-filled with the reps to hit next. Use the exit rules in the progression table to choose your next rung.
