Heels on the ball, curl it in for sneaky-hard hamstrings.
Keep your hips lifted as you curl, don't let them drop when the ball comes in.
The Stability Ball Leg Curl isolates the Hamstrings — no passengers. That makes it a clean tool for adding targeted hamstrings volume without extra fatigue.
The Stability Ball Leg Curl primarily works the Hamstrings.
Shorten the range or use an easier variation, and stop 1 to 2 reps before failure. Reps build fast when you train just shy of your limit.
For most lifters 3 to 4 working sets. Pick the rep range that fits your goal and progress the load when the top of the range feels owned.
