Physioball Hamstring Curl
Builds bilateral hamstring strength and posterior-chain control with an unstable rolling surface.
How to Do the Exercise
Setup
Lie on your back with both heels resting on a physioball and the legs comfortably straight.
How to perform it
Lift the hips into a bridge, bend both knees to roll the ball toward you, then slowly straighten the legs to roll the ball away while keeping the hips controlled.
Dosage
3 sets, 8–10 repetitions, Tempo 2-1-3, Rest 90 seconds
What to Focus On
Key cues
- Keep the hips elevated
- Pull the ball in with the hamstrings
- Control the roll-out slowly
- Keep the pelvis level
Why use it
Builds bilateral hamstring strength and posterior-chain control with an unstable rolling surface.
When to use it
Useful when bridge control is established and a dynamic bilateral hamstring-curl challenge is appropriate.
Common mistakes
- Dropping the hips during the curl
- Rolling the ball too quickly
- Letting the pelvis rotate
- Using a range that causes repeated cramping
Know When to Progress or Scale Back
Use your movement quality and symptom response to decide whether the current version still fits.
Progress when
- You can keep the hips controlled throughout the full range
- The roll-out remains slow
- Symptoms settle appropriately afterward
Scale back if
- The hips repeatedly drop
- Hamstrings cramp or the ball becomes difficult to control
- Pain remains meaningfully worse afterward
Was This the Right Challenge Today?
Use the same three signals that matter inside Therapeutic Edge recovery plans: how challenging the exercise felt, how well you controlled it, and how your body responded afterward.
Answer after the exercise and, when possible, after you know your later or next-day response. This checks one exercise today; it does not change or save a rehab plan.
