Target you butt and thighs while strengthening you hips and back.

Stand tall with chest lifted, and lightly hold the back of a chair. With hips facing forward, turn your right foot out 45 degrees, then lift your right leg straight behind you. Squeeze your lower back and glutes to lift leg as high as you can without straining your back. Return to start, and do 10 repetitions. Repeat using left leg, alternating for 3 sets per side.
