Setup
- Adjust the backrest so your knees align perfectly with the machine's pivot point.
- Position the lower leg pad just above your heels, against the lower Achilles tendon.
- Lower the thigh stabilizer pad firmly against your quads to prevent your hips from lifting.
- Grasp the handles on the side of the machine to secure your upper body and stabilize your pelvis.
How to do it
- Exhale as you curl your heels toward your glutes in a smooth, controlled motion.
- Squeeze your hamstrings hard at the bottom of the movement for a one-second peak contraction.
- Inhale as you slowly return the weight to the starting position, maintaining constant tension on the hamstrings.
- Maintain a controlled tempo, typically 2 seconds for the curl and 3 seconds for the return.
Form checklist
- Keep your lower back pressed firmly against the backrest throughout the set.
- Ensure your hips do not lift off the seat as you curl the weight down.
- Avoid using momentum or swinging your torso to move the weight.
- Keep your feet in a neutral or dorsiflexed (toes toward shins) position to maximize hamstring tension.
Pro tips
- Focus on 'pulling' through your heels rather than pushing with your feet to enhance the mind-muscle connection.
- Keep your toes pointed toward your shins to reduce calf involvement and force the hamstrings to do more work.
Make it harder
- Implement a 3-5 second eccentric (lowering) phase to increase time under tension.
- Add a 2-second pause at the point of maximum contraction (bottom of the movement) on every rep.
