Works on: Oblique abdominals and lower back.

Setup: Kneel on the ground with your right side next to a ball. Hug the ball between your right arm and your side, then lie down on the ball. Spread the legs widely in a forward/backward stance for stability. Use your legs to roll your torso up onto the ball until you are lying on the outside of your hip.

Steps: Cross your arms across the chest and perform a side crunch to theleft. Slowly return and repeat.

Repetitions: Three sets of 15 to 25.

Precautions: Perform this exercise in an open area in case you fall off the ball.

Options: For more challenge, roll more of your torso up and over the top of the ball.
