Sitting Isometric Hamstring Curl Hold with Stability Ball
Seated on a bench end with a stability ball behind the calves, press the heels back into the ball and hold; the hamstrings work without moving.
How to do it
Setup
Seated tall at the bench end, a stability ball wedged between the calves and the bench, feet on the floor, hands on the bench.
Steps
- Press the calves and heels back into the ball.
- Hold and breathe; time it.
- Ease off the press slowly at the end.
Common mistakes
Pushing by leaning back: sit tall; the legs do the pressing. Squeezing so hard the ball shoots out: firm, steady pressure. Breath held to push harder: keep breathing evenly.
Breathing
Steady throughout; never held.
