Instructions
Preparation
- Facing bench, stand between bench and lever pads. Lie prone on bench with knees just beyond edge of bench and lower legs under lever pads. Grasp handles.
Execution
- Raise lever pad to back of thighs by flexing knees. Lower lever pads until knees are straight. Repeat.
Comments
- Keep torso on bench to reduce hyperextension of the lower back. Most machines are angled at the users hip to position the hamstring in a more favorable mechanical position. If this angle is sharp (as shown), Rectus Femoris is less likely involved as Antagonist Stabilizer. Dorsal flexion of the ankle reduces active insufficiency of the Gastrocnemius allowing it to assist in knee flexion. See Knee flexion abduction force vector diagram.
