1. Lay on the floor as if you were doing
regular crunches. Starting at your waist, turn your legs
completely to the left side. Place your hands behind your
head for support.
2. Lift your head up slightly off the
ground as if you were doing a regular crunch.
3. Lower your head back down so it almost
touches the ground. After desired number of reps is achieved,
repeat exercise on other side.
Tip: To avoid bending your neck forward
and straining it, try keeping your eyes on the ceiling
while doing the crunches.
