- Intermediate

Setup
- Load the desired weight plates onto the machine's loading peg.
- Adjust the roller pad so it sits just above your heel or lower Achilles tendon when your leg is fully extended.
- Place your non-working knee on the support pad and grip the handles firmly to stabilize your upper body.
- Position the working leg's knee against the pivot pad, ensuring your thigh is flush against the support and aligned with the machine's axis.
How to do it
- Exhale as you curl your heel toward your glutes in a smooth, controlled arc, keeping your hips pressed into the pad.
- Squeeze your hamstrings hard at the top of the movement for a one-second peak contraction.
- Inhale as you slowly lower the weight back to the starting position over a 2-3 second count, stopping just before the weight stack touches.
- Complete the full set on one leg before switching to the opposite side.
Form checklist
- Keep your hips pressed firmly against the front pad to prevent lower back arching.
- Maintain a neutral spine and avoid swinging your torso for momentum.
- Ensure the roller pad stays in contact with your lower leg throughout the entire rep.
- Keep your ankle flexed (toes toward the shin) to focus the load on the hamstrings.
Pro tips
- Focus on the mind-muscle connection by imagining pulling the weight with your heel rather than just moving your foot.
- Keep your hips 'heavy' against the machine to prevent the pelvis from tilting, which keeps the tension strictly on the hamstrings.
Make it harder
- Perform a 4-second slow eccentric (lowering) phase to maximize muscle fiber breakdown.
- Incorporate a 2-second isometric hold at the point of maximum contraction (the top of the curl).
