Leg Curl (on stability ball)
The leg curl on a stability ball targets the hamstrings while also engaging the core for stability.
- Start by lying on your back with your heels resting on the stability ball.
- Lift your hips off the ground, forming a straight line from your shoulders to your heels.
- Pull the ball towards you by bending your knees, keeping your hips elevated.
- Extend your legs back to the starting position while maintaining hip elevation.
How to perform the Leg Curl (on stability ball)
- Set up. Set up in a stable, balanced starting position appropriate for the Leg Curl (on stability ball) using your stability ball.
- Brace and execute. Brace your core, control the descent, and move through a full pain-free range of motion while emphasizing your calves.
- Reset. Reverse the movement under control and reset between repetitions, keeping your form crisp on every rep.
Coaching cues
- Move with intent — every rep should feel deliberate, not rushed.
- Drive force through your calves rather than momentum.
- Keep your breathing steady: exhale on the hard part, inhale on the reset.
Common mistakes
- Using too much weight and losing positional control.
- Cutting the range of motion short and missing the target muscle.
- Letting your spine round or hyperextend instead of staying neutral.
