Exercise: Abdominal Crunch with Exercise Band & Exercise Ball

Lay stretched out on your back on a gym mat or on the floor with the ball under your calves. Loop the exercise band around a table or chair leg (or something else sturdy that won't move) and hold the ends of the band with arms almost straight over your head.

Bring your elbows in to your sides, then lift your shoulders and head slightly off the mat. Hold for a few seconds, then lower. Make sure you don't hold your breath.

Do 10 - 12 repetitions of the exercise. Rest briefly. Repeat for 1 or 2 more sets.
