Begin in a supine position with your feet on a pair of sliders and your hands directly underneath your shoulders. Your fingertips should be pointing toward your feet.
Your feet should be hip-width apart and your legs should have a slight bend in them. Flex your feet and press your heels into the sliders. Be sure to keep a soft bend at your elbow joints.
Bend your right leg as you slide your right heel closer to your hands. Extend it back out and then repeat with the left heel. Complete five reps on each side.
Repeat the same movement, but slightly faster, for 10 reps.
Next, extend both legs out, maintaining a slight bend in your knees and slowly bring both heels toward your hands. Complete 10 reps.
Finally, hold both legs in a bent position as you begin to bend your arms and pulse for 10 reps.
