Assisted Prone Hamstring
Assisted Prone Hamstring Exercise Description
The Assisted Prone Hamstring is a partner-resisted hamstring curl performed lying face down. It targets the hamstring group (biceps femoris, semitendinosus, semimembranosus) through the knee flexion movement pattern, with possible assistance from the gastrocnemius. Manual resistance allows you to control the load across the full range of motion without machines, emphasizing smooth concentric and eccentric control. The goal is to flex the knee while keeping the pelvis level and the spine in neutral, minimizing hip movement and lumbar extension. Clear communication with the partner is essential so resistance remains steady, safe, and within a comfortable, pain‑free range.

How To Do The Assisted Prone Hamstring Exercise
‘- Lie prone on a bench or firm mat with legs straight and feet off the edge if possible. Forehead on a towel. Brace your core to maintain a neutral spine and level pelvis.
– Dorsiflex the working ankle (toes toward the shin). Keep both hips square to the surface.
– Partner stands at the side. One hand gently stabilizes the posterior thigh above the knee; the other hand holds the lower leg just above the ankle (not on the knee or Achilles).
– Initiate by squeezing the hamstrings to flex the knee, drawing the heel toward the glute.
– Partner provides smooth, even resistance opposite the movement so you can move under control—no jerking.
– Stop before the pelvis tilts, the thigh lifts off the surface, or motion becomes uncomfortable.
– Lower the leg slowly to the start while the partner maintains light, steady opposing resistance.
– Breathe continuously; avoid holding your breath.
– Switch legs and repeat with the same setup.
– Avoid: arching the low back, rotating the hips, pressing on the knee joint, or letting the partner move the limb for you.
Assisted Prone Hamstring Tips
‘- Brace your core to keep a neutral spine and level pelvis while lying prone.
– Position your legs straight with feet off the edge of the bench or mat if possible.
– Dorsiflex your working ankle by pulling your toes toward your shin before and during the curl.
– Keep both hips square to the surface to minimize hip rotation.
– Have your partner stabilize the thigh above the knee with one hand and hold the lower leg just above the ankle with the other.
– Initiate the movement by actively squeezing your hamstrings to flex the knee and draw the heel toward the glute.
– Ask your partner to give smooth, even resistance in the opposite direction of your movement—no jerking.
– Stop the curl before your pelvis tilts, your thigh lifts off the surface, or the motion feels uncomfortable.
– Lower the leg slowly to the start position while your partner maintains light, steady opposing resistance.
– Breathe continuously throughout the set and avoid holding your breath.
Assisted Prone Hamstring Beginner Introduction
The Assisted Prone Hamstring is a partner-based leg curl done while lying on the stomach, designed to challenge the back of the thighs without using machines. The person exercising bends the knee against the partner’s hands, which provide steady manual resistance as the heel moves toward the backside and then returns to the start. This bending-and-straightening pattern highlights the hamstrings, with some help from the calves, while the hips and lower back remain quiet on the bench or mat.
Because a partner controls the resistance with their hands, the effort can match the lifter’s strength through every part of the motion, allowing very deliberate lifting and lowering. Attention to a still pelvis, a calm lower back, and an aligned spine turns this into a control-focused exercise rather than a momentum-based one. Consistent, clear communication between partners supports smooth resistance, comfortable effort, and a pain‑free range, while light stabilization of the thigh helps direct the work into the back of the leg instead of the hips or spine.
