How to do it

Setup

On your back, heels on the ball, hips lifted into a line, arms on the floor.

Steps

  1. Curl the heels toward the hips, rolling the ball in.
  2. Keep the hips high the whole time.
  3. Roll it back out with control.

Common mistakes

Hips dropping as the ball rolls: the bridge holds through the whole rep. Yanking the ball in: smooth curl. Arms pushing off: light touch, core balances.

Breathing

Exhale on the curl, inhale rolling out.
