How to do it

1. Lie on the floor with your legs straight, feet together, and arms extended behind your head. Your heels, thighs, butt, upper back, shoulders, head, and forearms should be in contact with the floor.
2. Take a deep breath, engage your abs, and initiate the movement by simultaneously raising your torso and legs toward one another.
3. As you raise your torso and legs, keep your arms in line with your upper body.
4. Near the end of the repetition, allow your arms to lean toward your legs slightly and tap your shins with your fingers.
5. As you exhale, slowly return to the starting position.
6. Take another breath and repeat.
