This exercise strengthens the muscles around your hip bones, which are vulnerable to fracture, and can help to improve balance. To begin, place your hand on a counter or against a wall for balance, and set your feet hip-width apart. Shift your weight onto your left foot, then straighten your right leg and lift it out in front of you until your right foot is about 6 inches off the floor. Do a set of 8 to 12 lifts, then shift your weight to your right foot and repeat the motion with your left leg.
