Pelvic rocking

This exercise strengthens your back, hip, and abdomen muscles.

1. Kneeling on hands and knees, place your hands directly under your shoulders and your knees under your hips.
2. Inhale deeply.
3. While slowly exhaling, pull in your abdomen, and tighten your buttocks and pelvic floor muscles. This should curve your spine into a 'C.'
4. Relax, keeping your back straight (don't allow it to curve toward the floor).
5. Do this exercise 8 times or to your comfort level.
