Power, Precision, and Performance

The JAWS Force Iso-Lateral Laying Leg Curl is built to target the hamstring group with biomechanical excellence. From its independent iso-lateral movement to its plate-loaded resistance, this machine allows users to train with maximum control, perfect form, and peak muscle engagement.

Key Features & Benefits

Independent Iso-Lateral Movement
Each leg works separately, which helps address strength imbalances, improves muscular symmetry, and promotes balanced development. Ideal for unilateral training or rehab.
Consistent, Smooth Resistance through Full Range of Motion
Advanced linkage and pivot points maintain constant tension during curling and lowering phases to maximise hamstring activation without drop-off or “dead zones.”
Comfort and Adjustability
Adjustable chest pad, thigh clamp pad, and ankle roller pad to suit varying body sizes and limb lengths. Low step-over or lying position ensures easy entry and exit. High-density foam and commercial-grade upholstery ensure comfort even under heavy loads or high volumes.
Heavy-Duty Build Quality
Constructed with thick steel frame, sealed bearings or bushings, and sturdy pivots. Powder-coated finish resists wear, and all welds are reinforced. Designed for heavy use in commercial gym environments.
Plate-Loaded Resistance
Accepts standard 2” (50 mm) Olympic weight plates allowing flexibility in load. Users can add weight horns to increase capacity. No reliance on selector stacks means less maintenance and long-term reliability.

Muscle Engagement & Training Benefits

Maximum recruitment of hamstrings—including biceps femoris, semitendinosus, semimembranosus—through controlled contraction.
Helps develop strength and endurance in the posterior chain, improves knee flexion control, and supports joint health.
Valuable for athletes, bodybuilding/hypertrophy work, injury prevention/recovery protocols, and performance conditioning.
Allows both high-volume work (for shaping and endurance) and heavy loads (for strength and power) with one machine.
