🦵 Squat Form Guide
Build the foundation of lower-body power.
The squat is the most fundamental lower-body movement in strength training. SportsReflector's AI tracks knee tracking, depth, forward lean, hip hinge pattern, and bar position to give you a 0–100 form score and identify exactly what's holding back your squat.

5 Squat Mistakes AI Catches
These are the most common Squat form errors — and the ones most likely to cause injury or limit your progress.
The knees collapsing inward during the ascent is the most common squat error. It increases MCL and ACL stress and reduces power output.
Fix: Cue 'knees out' throughout the movement. Strengthen glute medius with banded walks and clamshells. Improve ankle dorsiflexion if heels rise.
Not reaching parallel (hip crease below knee) reduces glute and hamstring activation and limits strength development.
Fix: Work on ankle and hip mobility. Use heel elevation temporarily while building mobility. Record from the side — AI depth detection is more accurate than self-assessment.
Excessive torso forward lean shifts load to the lower back and away from the quads and glutes.
Fix: Improve thoracic mobility and ankle dorsiflexion. Widen stance slightly. Consider a high-bar vs low-bar position based on your proportions.
Heels coming off the floor indicates insufficient ankle dorsiflexion, forcing the knees forward and the torso to lean.
Fix: Daily ankle mobility work (wall ankle stretch, calf stretches). Use 5–10mm heel elevation as a short-term fix while building mobility.
Hips rising faster than shoulders at the bottom of the squat converts the movement into a good morning, stressing the lower back.
Fix: Focus on 'chest up' and 'drive through the floor' cues. Reduce weight and rebuild the pattern. Pause squats at the bottom build positional strength.

Knee Cave During Squats: Causes, Fixes, and When to Worry
Knee cave during squats is blamed on weak glutes — but the research shows it is more complex than that. Understanding the actual causes of valgus collapse leads to more effective and faster fixes.
How to Squat Below Parallel: Mobility Fixes and Technique Adjustments
Squatting below parallel requires adequate ankle dorsiflexion, hip mobility, and thoracic spine extension. This guide identifies the most common restrictions and provides targeted mobility work and technique adjustments for each.
7 Squat Mistakes AI Catches That Coaches Miss
Coaches watch your squat from one angle. AI tracks 25 body joints simultaneously from every angle, catching errors that are invisible to the human eye — including the ones causing your knee pain.
Knee Pain on Squats Is Almost Never a Knee Problem
If you experience knee pain during squats, the instinct is to rest the knee. But sports science research consistently shows that squat-related knee pain originates upstream — in hip mobility, ankle dorsiflexion, or foot position.
