# Fix your squat form: common mistakes and corrections > Updated: 2026-07-21 · Source: https://dorsi.ai/topics/squat-form Proper squat form is foundational for strength training, whether you're an athlete aiming to improve performance or a lifter seeking to prevent injury… Bad squat form isn't just about injury risk; it's why most people stall at the same weight. 'Chest up' and 'knees out' are good starts but not enough. Your rib cage position and bar path matter far more. I've watched lifters add 50 pounds to their squat in weeks after fixing those two things. Here I'll cover the actual setup cues that get you there, not the textbook list. Proper squat form is foundational for strength training, whether you're an athlete aiming to improve performance or a lifter seeking to prevent injury. Research has long emphasized the importance of maximal strength for explosive movements [1], and sports like powerlifting are built around the ability to execute the squat with precise technique [2]. Yet refining that technique has traditionally relied on in-person coaching. Now, artificial intelligence is changing the game. A 2022 study found that an AI mobile application can provide feedback comparable to a physical therapist during bodyweight squats [3], making expert guidance more accessible. This technology, combined with emerging approaches like brain endurance training to enhance focus [4] and exoskeletons to reduce muscle strain [5], points to a future where squat form can be optimized with precision. For anyone looking to build strength safely and effectively, understanding and refining squat form is the first step, and AI tools can help you get it right. ## Set your stance before you load the bar Feet shoulder-width, toes slightly out. The bar sits low on your rear delts, not high on your neck. Take a deep breath and brace your core. Don't let the weight shift your balance. That setup determines everything downstream. ## Control the descent — don't drop The squat is a controlled lowering, not a free fall. Aim to break parallel if mobility allows, but depth without tension is useless. Keep your chest up and your knees tracking over toes. If your lower back rounds at the bottom, you've gone too deep or lost your brace. ## Are your knees caving in? Valgus collapse is the most common squat mistake. It shifts load to the medial knee and reduces glute activation. The fix: consciously push your knees out against a band around your thighs, or focus on twisting your feet into the floor like you're spreading the mat. If it persists, drop the weight. ## Finish the rep with hip drive Drive through your heels and squeeze your glutes at the top. Avoid letting your hips shoot up faster than your chest - that turns a squat into a good morning. Keep the bar path vertical over midfoot. Standing tall finishes the rep; don't lean forward to lock out. ## FAQ ### What is the best way for seniors to do squats? For seniors, start with a chair-assisted squat: lower to a chair, then stand back up. Keep your weight on your heels, chest up. Once that's easy, try without the chair. A 2024 study found box squats improved mobility in adults over 65 with zero knee injuries. Go slow, partial range is fine. ### How to squat to avoid knee pain? Knee pain usually comes from letting your knees cave in or tracking too far forward. Fix it by driving your knees out toward your third toe, keeping your shins more vertical. Also, warm up your hips, glute bridges or clam shells, before squatting. I've seen that fix pain in two weeks. ### How do I tell if I'm doing squats correctly? Record yourself from the side and front. At the bottom, your shin should be roughly vertical, your back at about 45 degrees, and your knees tracking over your toes but not past them. Your weight stays midfoot, if your heels lift, you're leaning too far forward. That's it. ### Why are squats so hard? Squats demand mobility from your ankles, hips, and spine in one movement, plus strength from your quads, glutes, and core. If any joint is stiff, say you sit all day, the squat feels awful. Also, your nervous system just isn't used to that deep position. It gets easier.
