Lever Lying Single Leg Curl
- Intermediate
- Isolation
- Rep-based
- Lower legs
The Lever Lying Single Leg Curl is a unilateral isolation exercise that targets the hamstrings individually to correct muscle imbalances and enhance mind-muscle connection. By focusing on one leg at a time, you ensure equal strength development and maximize the peak contraction of the posterior chain.

Setup
- Adjust the lever arm so the padded roller sits comfortably just above your heel/Achilles tendon.
- Lie face down on the machine, ensuring your knee joint is perfectly aligned with the machine's pivot point.
- Grasp the handles firmly and brace your core to stabilize your torso against the bench.
- Position the working leg under the roller and keep the non-working leg relaxed or braced against the machine frame.
How to do it
- Exhale as you curl the weight upward toward your glutes in a smooth, controlled arc.
- Squeeze your hamstring hard at the top of the movement for a one-second pause.
- Inhale as you slowly lower the weight back to the starting position, stopping just before the weight stack touches to maintain tension.
- Perform all repetitions on one side before switching to the other leg.
Form checklist
- Keep your hips pressed firmly into the pad to prevent lower back arching.
- Ensure your knee stays aligned with the machine's axis of rotation throughout the set.
- Keep your toes pulled toward your shin (dorsiflexion) to better engage the hamstrings.
- Avoid using momentum or 'kicking' the weight up; maintain a steady 2-1-2 tempo.
Pro tips
- Focus on driving your quads into the bench to stabilize the pelvis, which forces the hamstrings to do all the work.
- Imagine pulling the weight with your heel rather than your foot to improve the mind-muscle connection with the hamstring belly.
Make it harder
- Implement a 3-4 second eccentric (lowering) phase to increase time under tension and muscle fiber recruitment.
- Add a 'pause-and-squeeze' at the top of each rep, holding the peak contraction for 2-3 seconds.
