foot down?

[leftypitcher934]

i recently went to pitching lessons and a coach there said that while my leg is up at about 90 degrees that my foot should be pointed down.. why should it be pointed down what does it do?

Down, up. Doesn't matter. Do whatever keeps you balanced. With the foot up, you're using the muscles around the shin to keep balanced. With the foot down, you'r using the calf muscles. Different people use different muscles to maintain balance.
