Kneeling Single Hamstring Curl
Kneeling Single Hamstring Curl Exercise Description
The Kneeling Single Hamstring Curl is a bodyweight knee‑flexion drill performed in a quadruped position to target the hamstrings of one leg at a time. You’ll bend the knee against gravity while keeping the hip and pelvis steady, emphasizing control and full, pain‑free range. Primary movers are the hamstrings (biceps femoris, semitendinosus, semimembranosus); the gastrocnemius may assist. The gluteals and trunk musculature act isometrically to stabilize the hip and maintain a neutral spine. This variation is useful for practicing clean knee flexion mechanics and building awareness without external load.

How To Do The Kneeling Single Hamstring Curl Exercise
‘- Start on all fours: hands under shoulders, knees under hips, fingers spread, spine neutral, ribs stacked over pelvis.
– Brace lightly through the midsection and keep your pelvis square to the floor.
– Keep the left knee down. Lift the right thigh just off the floor so the hip stays level and the thigh stays still.
– Dorsiflex the right ankle (toes toward shin).
– Curl by bending the right knee, drawing the heel toward the glute without letting the thigh drift or the low back arch.
– Pause briefly near your available end range while maintaining a steady pelvis.
– Lower the foot back with control until the knee is nearly straight—do not hyperextend.
– Keep hips level throughout; avoid rotating, hiking, or letting the working knee flare outward.
– Maintain a quiet upper body: press the floor gently, shoulders away from ears, neck long.
– Complete the desired number of controlled repetitions on the right, then switch legs.
Kneeling Single Hamstring Curl Tips
‘- Set up on all fours with hands under shoulders, knees under hips, and a neutral spine with ribs stacked over the pelvis.
– Brace lightly through your midsection and keep your pelvis square to the floor before you start curling.
– Keep the support knee down and lift the working thigh just off the floor so the hip stays level and the thigh remains still.
– Dorsiflex the working ankle by drawing your toes toward your shin before and during the curl.
– Bend the working knee to draw your heel toward your glute without letting the thigh drift or your lower back arch.
– Pause briefly near your available end range while keeping the pelvis steady.
– Lower the foot back with control until the knee is nearly straight, avoiding hyperextension.
– Keep the hips level throughout and avoid rotating, hiking, or letting the working knee flare outward.
– Maintain a quiet upper body by pressing the floor gently, keeping shoulders away from your ears, and your neck long.
– Perform all repetitions with smooth, controlled motion on one leg before switching to the other.
Kneeling Single Hamstring Curl Beginner Introduction
The Kneeling Single Hamstring Curl is a simple bodyweight knee‑bending exercise done on hands and knees that highlights one leg at a time. The working leg moves mainly at the knee, pulling the lower leg upward without swinging the thigh or shifting the hips. This makes the muscles along the back of the thigh the main drivers of the motion, with support from the calf. Because there is no added resistance, the emphasis sits on smooth control and moving only through a comfortable range.
While the lower leg curls and straightens, the rest of the body stays steady. The glutes and core work together to hold the pelvis still and the back in a natural line, while the shoulders and arms provide a stable base against the floor. This quiet, controlled setup allows attention to go toward how the knee joint is moving and how the back of the leg is working, making the drill useful for refining knee mechanics and building awareness before adding more challenging loading patterns.
