Circular Crunch

Trains all your abdominal muscles to contract at odd angles, which helps in sports where you have to run — especially when you bob and cut.

Cup your hands lightly over your ears, then slowly raise your head, shoulders, and feet off the floor. This is your starting position.

From the starting position, move your knees in a circle (as seen if you were looking down from above). Do this three times in each direction, making as wide a circle as you can.

Follow this exercise immediately with the Figure 8 Crunch.
