Stand up straight sideways, and place your left hand on the wall for support. Slowly raise your right leg sideways, as high as possible without bending your knee. If possible, try to bring it to a 90-degree angle. Then squeeze your glutes for 2 seconds, and bring back your leg down. After a repetition of 10, switch sides, and do another 10. For this workout, you may start off with a set of 2 and increase it over time.
