Lie on your stomach with your legs straight. Tighten the muscles in your bottom and the hamstring of one leg, and lift toward the ceiling. Hold 3-5 seconds, lower, and repeat. Do 10-15 lifts and switch sides. You can add ankle weights as you gain strength. You should not feel back pain. If you do, limit how high you lift up. If it’s still painful, stop and talk to your doctor.
