1) Set up your phone so the video is actually useful

Place your phone on a stable surface, tripod, or shelf at about hip height. The camera should be far enough away to capture your whole body from head to feet during the entire squat. If the frame cuts off your feet, knees, or hips, it will be much harder to judge form.

Use bright, even lighting and keep the background uncluttered. Film in plain clothes that let you see your knees, hips, and torso. If possible, record at 30 fps or higher in landscape mode so the movement looks smoother and easier to review.

2) Choose the best angle for squat form

For a basic squat check, film from two angles: side view and front view. The side view helps you see torso angle, depth, and whether your back stays neutral. The front view helps you spot knee collapse, uneven weight shift, and foot position.

Stand about 6 to 10 feet from the camera for the side view, with the lens roughly aligned with your hips. For the front view, place the camera directly in front of you. Avoid filming from a low angle close to the floor or from too far away, since both can distort what your body is doing.

3) Record a few reps and review the right checkpoints

Warm up first, then record 3 to 5 controlled reps at a weight you can manage safely. Squat at a normal speed instead of rushing. If you are checking bodyweight squats, keep your arms in a consistent position each rep so the video is easier to compare.

When you review the clip, look for these checkpoints: feet stay flat, knees track in line with toes, chest and torso stay controlled, heels do not pop up, and you lower with control rather than dropping fast. A slightly different torso angle is normal depending on your body proportions and squat style, but major rounding, wobbling, or knee cave-in are signs to fix.

4) Common mistakes to avoid when filming and squatting

Do not film only one rep if you want a reliable picture of your technique. A single rep can hide problems that show up on the second or third rep when fatigue or rhythm changes. Also avoid wearing baggy clothing that blocks your knee and hip positions.

Do not use the video to chase depth at the expense of control. If your lower back rounds, heels lift, or knees collapse just to go deeper, reduce the depth slightly and build it back up. If pain is part of the movement, stop and get personalized advice from a qualified professional.

5) Use the video to make one small correction at a time

Pick one issue to fix first, such as keeping your knees tracking over your toes or slowing the descent. Then re-record after a few practice reps. Small changes are easier to learn and easier to measure than trying to fix everything at once.

If you want a simpler way to compare reps over time, a tool like Fitnit can help by counting squats automatically and analyzing your movement from your phone camera. That can be useful when you are training alone and want quick feedback without setting up extra equipment.

Tips

• Film both a side view and a front view for the same set.
• Use a stable phone position at hip height, not a handheld selfie angle.
• Wear fitted clothing so you can see knee and hip motion clearly.
• Review the clip immediately after the set while the movement is fresh.
• Fix one form issue at a time and re-film to confirm the change.
