IRONPACK

Hollow Body Hold

Muscles worked: Abs.

How to do it

  1. Lie on your back with your arms overhead and legs straight.
  2. Press your low back flat into the floor and hold it there.
  3. Lift your shoulders and heels a few inches so both hover.
  4. Keep the arms and legs long, low back still pinned down.
  5. Count the seconds. Tuck the knees if the low back lifts.

Coaching cues
