4 Leg Press Mistakes AI Catches
These are the most common Leg Press form errors — and the ones most likely to cause injury or limit your progress.
Fully locking out the knees at the top of the leg press hyperextends the joint and removes tension from the muscles.
Fix: Stop just short of full lockout (maintain a slight bend). Keep constant tension on the quads throughout the movement.
Allowing the hips to lift off the seat at the bottom of the movement indicates excessive depth and places stress on the lower back.
Fix: Reduce the range of motion until the hips stay flat. Build hip flexor mobility over time to increase depth safely.
Placing feet too low increases knee stress and reduces glute/hamstring involvement.
Fix: Position feet at mid-platform height. Higher foot placement emphasizes glutes and hamstrings; lower placement emphasizes quads but increases knee stress.
Knee valgus during the leg press indicates weak hip abductors and increases knee injury risk.
Fix: Place feet shoulder-width apart with toes slightly out. Use a resistance band above the knees to cue abduction. Strengthen glute medius.

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.
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.
