Superman.

Make every rep count.

1. 01

   Lie face down with legs straight and feet together. Keep your arms by your sides (or clasped behind your back) and your neck neutral, looking at the floor.

2. 02

   Brace your core and squeeze your glutes, then lift your chest and legs slightly off the ground by contracting your lower back. Keep the movement smooth—don’t crank your neck or fling your body up.

3. 03

   Pause briefly at the top while breathing steadily.

4. 04

   Lower with control back to the floor and repeat for the prescribed reps.
