Begin in a side lying position with both limbs flexed to about 60° at the hip and 90° at the knee. Position the elbow beneath the shoulder nearest the ground. Press the forearm into the floor and lift the hips off the floor into a side bridge. Hold this lateral pillar position, and subsequently perform a clam by raising the top knee so that the hip is in 30° of abduction, before returning to the starting position while keeping both heels in contact with each other.

Often, I will place a small towel roll between the feet to ensure consistent contact between the heels. Perform a set of 10-15 repetitions. Switch sides and repeat. Perform 2-3 sets.
