The JAWS Prime Twin-Force™ Biceps Curl Machine sets a new benchmark for precision arm training.

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:

1. Matching the Strength Curve – Delivers load where your biceps can handle it, easing where they can’t.

2. Isolating Each Arm – Each arm has its own resistance path and stack, allowing you to train equally or focus more on a weaker side.

3. 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.

Using the Twin-Force™ Biceps Curl Machine

1. Set Up
   Adjust the seat so that your elbows align directly with the pivot points. Rest your upper arms on the pads and select your desired weight for each stack.

2. Choose Your Style

   • Symmetrical curls – Lift with both arms together for maximum load.

   • Alternating curls – Train each arm in turn for improved focus and endurance.

   • Single-arm isolation – Target a weaker arm to bring up strength and size balance.

3. Execution
   Curl the handles smoothly towards your shoulders, squeezing at the top before lowering under control. Avoid jerking or swinging to maintain constant tension.
