Q: What is the Lying Prone Leg Curl Machine?

The Lying Prone Leg Curl Machine is a isolation (single-joint) resistance exercise targeting the Hamstrings (Biceps Femoris & Semitendinosus) and Legs. Direct knee flexion isolation for the posterior leg sweep. The angled bench places the hip in slight flexion, putting hamstrings in optimal stretch position.

list_alt STEP-BY-STEP BIOMECHANICAL EXECUTION

Pad Alignment & Axis Setup

Lie facedown with knees just off edge of bench, aligned with rotational axis. Adjust roller pad just below calves/Achilles tendon.

                    VECTOR CUE: Knees just off pad edge • Roller pad against lower Achilles • Grip handles
                  

Pelvic Anchor to Bench

Press your hips firmly down into the angled bench and brace abs to prevent hyperextending lower back.

                    VECTOR CUE: Push hips down into bench • Keep toes pointed/dorsiflexed
                  

Curl Heels to Glutes

Curl legs upward by contracting hamstrings until the roller pad nears your glutes.

                    VECTOR CUE: Curl heels toward butt • 1-second hard hamstring contraction
                  

Slow Negative Extension

Lower weight slowly over 2-3 seconds back to almost straight legs.

                    VECTOR CUE: 2-3s negative • Full hamstring stretch • Don't let weights slam
