Swiss Ball Leg Curl
The Swiss ball leg curl uses an exercise ball to create an unstable hamstring curl that demands core stability. Lie on your back with heels on the ball, bridge up, then roll the ball toward your glutes using hamstring flexion.
How to Perform
Lie on your back and place your heels on top of a Swiss ball.
Bridge your hips up so your body forms a straight line from shoulders to heels.
Curl the ball toward your glutes by digging your heels in and flexing your knees.
Extend back out slowly, keeping hips elevated throughout the entire set.
Common Mistakes to Avoid
Dropping the hips between reps, losing the bridge position and reducing hamstring load.
Using momentum to roll the ball instead of a controlled hamstring contraction.
Placing the ball too far away, making it impossible to curl through full range.
