Lower body muscles in free throw shot?

Answer 1

Lower body muscles are important in the free throw shot. Essentially, a perfect free throw shot is dependent on the timing of the shot. The lower body muscles should be used to generate a good deal of the power; this power can be harnessed to its fullest at the perfect timing.

The lower body muscles also provide stability during the shot. If you do not bend your knees when you shoot the ball, the ball moves more erratically.
