Built for Balanced Performance

The JAWS Prime Seated Leg Curl provides a stable exercise base with an architecture designed around correct biomechanics. The padded seat and backrest position the user comfortably, with a reinforced thigh stop to prevent unwanted movement. Roles are balanced via smooth, sealed-bearing pulleys and a robust cable path that guarantees even resistance on both concentric and eccentric phases.

110 kg Stack: Efficiency Meets Adequacy

A 110 kg selector weight stack is plentiful for leg curl motion, enabling effective progression for all user levels – from beginners to strong athletic populations. The weight stack is built with 5 kg plate increments, offering fine-grained control for training variables like volume, strength development, and hypertrophy focus. Unlike systems that overshoot the required range, this load is optimized for the biomechanics of the hamstring movement, keeping programming lean and purposeful.

Aligned Movement for Joint Safety & Muscle Activation

Central to the design is the precise alignment of the machine’s pivot with the knee joint – creating a smooth and natural path of motion. The fulcrum delivers:

• Optimal knee tracking, protecting ligaments and joints

• A movement arc that encourages consistent muscular tension

• Controlled full range of motion from stretch to contraction

This alignment, combined with an adjustable shin pad, creates an exercise that feels safe, effective, and repeatable across workouts, without joint strain.

User‑Friendly Adjustability

The JAWS Prime Seated Leg Curl redefines ease of use with thoughtful adjustments for every user:

• Seat fore‑aft alignment via gas‑assist lever for torso positioning

• Shin pad height and pivot distance adjustment on ergonomic levers

• Backrest angle control to support spinal alignment

• Start‑range limiter, so users can set their preferred stretch start

Every setting is easy to access and operate while seated, complete with numbered stops and pop‑pin indicators to streamline setup.

Premium Smoothness – Every Rep

Under load, the action feels seamless thanks to:

• Sealed‑bearing pulleys, enabling effortless cable flow

• Durable cables and fittings designed for heavy, daily use

• Precision guide rods and weight plates for balanced resistance

This consistency allows users to focus fully on muscle activation and training intent—not distractions from equipment feedback.

Commercial Quality You Can Trust

• The heavy‑gauge steel frame ensures structural rigidity during heavy sets

• Powder‑coat finish resists wear, abrasions, and corrosion

• Moisture‑resistant upholstery maintains comfort and hygiene

• Stable platform and footrest system prevents shift or rock under load

This machine is built to handle frequent heavy usage—as standard in PT studios, commercial gyms, or athletic training centres.

Fit, Flow & Visual Appeal

With a footprint of approximately 170 cm × 120 cm × 155 cm, the machine balances user space with floor efficiency. Its sleek all-black finish blends seamlessly into modern gyms, yet offers a professional presentation. Custom colour options for frame and upholstery allow facilities to coordinate branding and interior design – with no compromise on build quality.

Five Stars for Programming Versatility

• Hypertrophy work (higher reps, sustained tension)

• Strength development (heavier loads, controlled tempo)

• Unilateral corrective use (set up each leg individually)

• Rehab protocols (partial range, controlled negative work)

• Circuit training (quick setup and effective sanitised seat transitions)

The consistent feel and adjustability support diverse programming—from isolation to complex session design.
