Get on the Ball: Bicycle Crunch
Not having a ball while you work your abs? Then try this fun variation of the bicycle crunch. It will not only work your abs and obliques, but since you're holding an exercise ball with your feet you'll work your hamstrings and inner thighs, too. Talk about an effective exercise. I highly recommend wearing sneakers to help you grip the ball. Get Flash to see this player. var so2428754 = Read more
