HOW: Begin this exercise by balancing on one leg. Once balance is achieved, shift your weight in circles on your stable leg. Rotate by placing most of your body weight from the outside of your foot, to your forefoot/toes, to the outside your foot, back towards you heal, and repeat. You can then also go the opposite direction. Start with small circles and increase the size of the circle you go through as you feel comfortable.
FEEL: You will feel all the small muscles of your foot work during this exercise.
COMPENSATION: Make sure the foot stays flat on the floor the entire time, don't allow certain parts of your foot to lose contact as you weight shift.
