Purpose: Strengthens the muscles on the underside of the foot. Corrects flat feet that are a result of weak musculature. Starting Position: Standing in a neutral position. Movement:
From the starting position, raise the underside of one foot, from the middle, in an attempt to create a dome.
Think about "pitching a tent", with its three points being under the heel, at the ball of the foot by the big toe, and at the ball of the foot by the baby toe.
Hold this position for 2-3 seconds, and then return to the starting position. Repeat for two sets of 20 repetitions.
