Stability Ball Hamstring Curl
On your back with the heels on the ball, lift the hips and curl the ball toward the glutes, then roll it out without dropping the hips.

How to do it
Setup
On your back, heels on the ball, hips lifted into a line, arms on the floor.
Steps
- Curl the heels toward the hips, rolling the ball in.
- Keep the hips high the whole time.
- 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.
