HOIST Roc It Selectorized Biceps Curl Machine
Description
The HOIST RS-2102 Biceps Curl is a commercial-grade selectorized strength machine engineered for serious arm development in gyms, fitness facilities, and training centers. Featuring HOIST's exclusive ROX™ technology, the machine uses a unique rocking motion that replicates the natural arc of a standing barbell or dumbbell curl - without placing stress on the lower back. The cable-driven design automatically adapts to varying arm lengths and shoulder widths, making it suitable for a wide range of users without manual adjustments.
Swiveling pulleys allow the user to select a pronated, neutral, or supinated grip, enabling targeted biceps activation from multiple angles. The machine begins each rep with the body in an upright posture to maximize arm extension and biceps recruitment, then rocks rearward to isolate the curl and minimize shoulder and back involvement. For any facility looking to offer premium upper-arm training, the RS-2102 sets the standard.

FAQ
What is ROX technology and why does it matter?
ROX (Rocking) technology is HOIST's patented motion system that allows the machine frame to rock rearward as you perform the curl. This replicates the natural movement path of a standing barbell curl - where the torso subtly shifts back during the lift - without actually engaging your lower back. The result is better biceps isolation, a more comfortable range of motion, and reduced injury risk compared to traditional fixed-axis curl machines.
What grip positions are available on the RS-2102?
The swiveling pulleys on the RS-2102 allow three grip options: pronated (palms facing down), neutral (palms facing each other), and supinated (palms facing up). Each grip targets the biceps and surrounding muscles slightly differently, making the RS-2102 a versatile tool for comprehensive arm development in a single machine.
How does the cable-driven system accommodate different users?
The cable-driven exercise movement automatically adjusts its path to accommodate users with different arm lengths and shoulder widths. This means a wide range of users can train on the same machine without needing to manually reconfigure settings for each person - making it ideal for high-traffic commercial environments.
Is professional installation required?
Given the machine's 563 lb. weight and commercial construction, professional delivery and installation are strongly recommended. The RS-2102 ships freight on a pallet. Please contact us at service@omahasportsandgames.com to coordinate delivery logistics and confirm installation details for your facility.
What does the optional 5 lb. weight upgrade include?
The optional 5 lb. weight upgrade (model RS-CAGE-NG-OPT1) adds 5 lbs. to the standard 255 lb. weight stack, bringing the total resistance to 260 lbs. (118 kg) and the total machine weight to 575 lbs. (261 kg). This upgrade is ideal for advanced athletes who need the extra incremental resistance at the top end of their training range.
