JAWS Prime Twin-Force™ Biceps Curl Machine
The JAWS Prime Twin-Force™ Biceps Curl Machine sets a new benchmark for precision arm training. Designed and engineered for lifters who demand both performance and durability, this premium selectorised machine combines anatomical accuracy with our Twin-Force™ Technology – delivering an arm-day experience that’s efficient, versatile, and tailored to every athlete.
Engineering That Works With You
Most curl machines offer a fixed path and a uniform load, but your biceps don’t work in a single, flat resistance pattern. The Twin-Force™ system is designed to match the muscle’s natural strength curve, ensuring peak tension at the right moment while maintaining smooth, controlled resistance from start-to-finish.
This means you’re not just “going through the motions” – you’re applying the most effective stimulus possible for strength and growth, every single rep.
Key Features
-
TWIN-FORCE™ Technology – Independent arm movement driven by two separate weight stacks for maximum versatility and unilateral power.
-
Iso-Lateral Design – Train each arm independently for balanced strength and improved symmetry.
-
Precision-Guided Pivot – Aligned perfectly with the elbow’s natural axis to protect joints and improve form.
-
Premium Adjustability – Fully adjustable seat height and arm pads to suit lifters of all sizes.
-
Commercial-Grade Build – Heavy-duty frame, reinforced welds, and anti-corrosion finish for long-term reliability in any training environment.
-
Smooth & Quiet – Sealed bearings and precision-engineered cams ensure fluid movement and whisper-quiet operation.
-
Easy Access Design – Step-through layout for quick entry and exit, ideal for busy gyms or rehabilitation settings.
Why Twin-Force™ Matters
Traditional selectorised biceps curl machines often load the muscle unevenly – too light when you’re weakest, too heavy at points where leverage drops. Twin-Force™ addresses this by:
-
Matching the Strength Curve – Delivers load where your biceps can handle it, easing where they can’t.
-
Isolating Each Arm – Each arm has its own resistance path and stack, allowing you to train equally or focus more on a weaker side.
-
Versatile Programming – Run symmetrical curls, alternating curls, or single-arm focus without changing machines or adjusting cables.
This translates into better quality reps, faster strength gains, and more effective hypertrophy stimulus.
Design Excellence
From its solid steel construction to its refined ergonomics, the JAWS Prime Twin-Force™ Biceps Curl Machine is built to blend performance with comfort. Every interaction point has been considered:
-
Ergonomic Arm Pads – Sculpted to hold the arm securely without unnecessary pressure on the forearm.
-
Large Selector Pins – Easy to grip and change weight quickly between sets.
-
Anti-Slip Foot Platforms – Keep you grounded and stable during heavy lifts.
-
Clear User Instructions – Integrated placard shows correct setup and movement pattern.
