Lie down on your back on the floor, facing the ceiling.

Lift your legs up in the air so they are at about a 90-degree angle with your body.

Draw your belly button in toward your spine.

Press your lower back against the floor to help eliminate your back from arching.

Extend your arms out to your sides, touching the floor beside you.

Pop your bottom off the floor by lifting your legs toward the ceiling.

Continue to repeat this movement until you feel your abdominals start to fatigue.

Rest.

Repeat.
