This exercise will improve strength throughout your oblique abdominal muscles.

Start by lying on your back with your knees straight and arms extended forward. Hold the Gray Cook Band and move your feet to the right at a 45 deg angle. Bring your chin to your chest and curl up one vertebrae at a time. Reach forward at the top. On the way down, reverse the pattern making sure you try to press the low back down first, then mid back, and then your head.

Complete 10-15 reps on each side.
