Exercise of the Week: Reverse Crunch with Exercise Ball

Difficulty: Easy to moderate

Start: Lie on back with arms relaxed on abdomen. Position ball behind legs so it can be lifted off floor with hamstrings/adductors.

Exercise: Lift ball just off floor. Pull stomach inward while inhaling. As you exhale, bring knees up toward chest, trying to lift buttocks off floor. Pause at top, then slowly return to starting position. Repeat 10-15 times.
