## Caption

Your glute maximus is a rotator, not just an extensor. When it shuts down, your knees, back and piriformis pay the price.
Knee cave in a squat is rarely a knee issue. It is often a glute that lost its rotational leverage. The gluteus maximus controls hip external rotation, and when it can't hold that angle, the femur drifts inward and the knee follows.
