Stability Ball Single-Leg Hamstring Curl

Lie supine with one heel on a stability ball, bridge hips up to level, and curl the ball toward your glutes through a full range of motion while holding the non-working leg elevated. Key points: - Keep hips elevated and level throughout the entire movement - Achieve a full eccentric extension and squeeze heel all the way to glutes - Engage core to resist pelvic tilting or dropping Common mistakes: Letting the hips drop toward the floor during the curl phase.
