90 DEGREES IS BEST

95.90 DEGREES IS BEST The goal on a set of leg presses is to bend your knees low enough to stimulate your quads without going too low and damaging the knees. For most people this means having a 90-degree angle between your upper and lower legs when the knees are bent. If you have no knee problems and have good flexibility, then lowering to 75 or 80 degrees is fine, but don't make the mistake that some individuals do and try bouncing your knees off your chest.
