Exercise Ball Leg Curl

Perform the exercise ball leg curl to strengthen your hamstrings and improve core stability.

  1. Lie on your back with your heels resting on the exercise ball.
  2. Lift your hips off the ground, creating a straight line from your shoulders to your heels.
  3. Pull the ball towards you by bending your knees, keeping your hips elevated.
  4. Extend your legs back to the starting position while maintaining hip elevation.

How to perform the Exercise Ball Leg Curl

  1. Set up. Set up in a stable, balanced starting position appropriate for the Exercise Ball Leg Curl using your stability ball.
  2. Brace and execute. Brace your core, control the descent, and move through a full pain-free range of motion while emphasizing your quadriceps.
  3. 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 quadriceps 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.
