Now it's time for a little core work on the ground that will also work the legs.
- Lying down, bend your left leg to 90 degrees with your foot on the ground; slightly bend your right in attitude position.
- Place your right arm behind your head, like you would in a crunch. Place your left hand at the side of your body.
- Curl your head up while extending your right leg and reaching your left hand across your body, then release to the ground. This completes one rep.
- Repeat 15 reps on this side, then hold in the lifted crossover position, lowering and lifting your right leg 10 times.
- Repeat on the other side.
