This is a safe and effective way to strengthen the muscles in your back that run parallel to your spine. Start with just a small range of motion and make sure your feet are touching the floor. This will help isolate and train those underworked areas of your back.

1 Lie face down on a flat padded surface or mat. Straighten your legs behind you with your toes facing the floor, your inner ankles facing each other. Place the palms of your hands on a round, full-length foam roller. Raise your elbows off the floor, pointing them to the sides.
