Movement:
Lie down on your back and raise your legs so they are pointing straight up toward the ceiling. Keep legs as straight as possible or slightly bent. Place your hands under your tailbone or along your sides with palms down. This is the starting position.
Begin exercise by raising your hips straight up off the ground, while keeping your legs perpendicular to the ground. Try not to let your legs fall backward or forward, but straight up. Pause slightly then slowly lower hips back down to starting position.
