HOW: Begin by lying on your side with the leg you want to exercise on top and the lower leg bent on the ground. The knee can be straight out from the hip. The bottom arm can be supporting your head, and the top arm can be bent with your hand on your hip. Keep your hips facing forward parallel to the ground. While keeping the knee straight and parallel to the ground, raise the top leg up and slightly move it forwards in front of you. From here, rotate your foot back and forth to point down to the floor and then up to the sky.
FEEL: You should feel the hip muscles on the side and front working to rotate the leg and hold it up.
COMPENSATION: Keep the knee straight, don’t bend it. Don’t let your leg drop down as you rotate your hip.
