Exercise IX: Straight-Leg Hip Extension
Sets: 2 Reps: 12 Rest: 45 Seconds
Lie on your left side on a flat bench with your left shoulder off the end and your right hand on a stool or the floor for support. Keep your left leg straight. Straighten your right leg and extend it 90 degrees in front of you-then let it hang off the bench so that your foot just touches the floor . Raise your right leg as high as you can without shifting your hips (your left hip bone must remain in contact with the bench) . Lower it back to the starting position. That's one rep. Complete all your reps, and then switch legs and repeat.
