Etenon R8302 Biceps Curl Machine, Double Pivot System and Two Grip Positions

In brief — Etenon R8302 Biceps Curl Machine, Double Pivot System and Two Grip Positions: dimensions 147.8 × 115.1 × 160.2 cm, weight 231.5 kg, material steel, brand Etenon, distributed by Light In Fitness, price 3,450.00 € excl. VAT.

The Etenon R8302 is a selectorised biceps curl machine with a double pivot system, two grip options and a counterbalanced arm, weighing 231.5 kg with a stack reaching 117.5 kg. The inclined arm support fixes the elbow in the optimal position and removes the swing that turns a free weight curl into a back exercise, so the load stays on the biceps brachii, the brachialis and the brachioradialis where it belongs.

The two grips are what make this more than a single exercise station. A supinated grip with the palms up recruits the short head of the biceps and the brachioradialis. A neutral hammer grip shifts the emphasis onto the brachialis and the supinator longus. Both are available on the same machine without changing attachment, which lets a member vary the stimulus across a training block from one seat.

The double pivot mechanism follows the natural kinematics of the elbow rather than forcing a single fixed arc, which reduces joint stress over high repetition counts. The counterbalanced arm removes the initial load at the start position so recruitment is clean from the first repetition. Seat height adjusts pneumatically without tools, the seat and arm support are high density antibacterial polyurethane, the selector pin is magnetic, and micro-loads of 2 by 2.5 kg allow finer progression than the stack increments alone. The electrostatic powder finish has been tested to over 800 hours of salt spray, and the manufacturer holds ISO 9001 and ISO 14001 certification.

Technical specification

Professional use and placement

Arm machines see short sets and high turnover, so they belong at the edge of the machine circuit where a queue does not block a route, ideally near the cable station and the pressing group since members combine the three. The pneumatic seat is the detail that makes the difference in a busy club: adjusting a curl machine with a pin between every member wastes more time than the set itself. Micro-loads of 2.5 kg matter for the same population, because on an isolation movement the jump between full stack increments is often too large to progress cleanly. Allow clear access to the front of the seat and behind the stack for maintenance. We position the arm and cable zone from your floor plan free of charge before quotation.

Frequently asked questions

What does the double pivot system change?

It lets the machine follow the elbow through its natural path instead of imposing a single fixed arc, which reduces joint loading and keeps the resistance aligned with the movement.

Why are micro-loads useful?

On an isolation exercise the working load is small, so a full plate increment can represent a large percentage jump. Micro-loads of 2.5 kg allow a member to progress in steps they can actually complete.

What does the salt spray test indicate?

It measures how long the powder finish resists corrosion in a controlled saline atmosphere. Over 800 hours indicates a finish specified well beyond normal indoor requirements, which matters in humid gyms and spa adjacent rooms.
