Lie on your left side in almost-fetal position with your knees bent and legs together so your ankles and knees are stacked on top of each other. Keeping your ankles together, lift your right knee, hold for three seconds and close. Do a set of 10, then roll over and repeat on the right side. You can also do the reverse clam: In the same starting position, lift your ankle while keeping your knees together. Do two sets of 10.
