Multipurpose Arm Trainer

Integrated resistance scroller sets 20 distinct positions from (0–20), covering 10–200kg (approx. 22–440lb). The dial is built into the hydraulic body for fast changes without tools or parts. Knurled texture improves grip while turning, and clear markings help you return to the same setting and record your preferred levels for different movements. Numbered scale is visible at a glance. Adjustment collar is sized for easy turning, even with sweaty hands, and stays integrated to avoid loose parts.

Resistance comes from a fully functional hydraulic cylinder housed in the center unit. The piston mechanism compresses under force and returns smoothly after each rep. The cylinder is integrated into the frame with a fixed rod and reinforced mounts to keep motion aligned. Designed for a consistent feel across the stroke and controlled springback, it supports repeatable reps with stable tracking and minimal play during use. Pairs with the 20-point dial to vary pressure across the 10–200 kg range.

Frame is built from double carbon steel tubing for rigidity and long-term durability. The outer arms use a dual-bar structure to support the center cylinder and keep alignment under load. Multiple fasteners and reinforced joints lock the assembly together. Steel construction resists bending during heavy presses and holds shape over time. Smooth edges and consistent spacing improve comfort and reduce pinch points while training. Hardware is evenly spaced for stability and centered alignment, too.

Handles feature anti-slip grip covers with a textured surface pattern to improve hold. Ergonomic contour supports multiple hand positions for presses and squeezes. Grip sections are fastened to the arms for a secure fit and consistent feel. The thicker outer padding adds comfort at contact points while keeping the core handle rigid. Curved ends help keep hands from sliding off during repeated reps. Dual-handle spacing matches frame for balanced leverage and helps keep wrist alignment consistent.

Built-in storage fasteners let you secure the arms together when not in use. Closing the trainer reduces its profile for packing and keeps the handles from opening in a bag. The fastener points are positioned near the ends for quick clipping and unclipping. This simple lock feature helps keep the unit organized in a closet, drawer, or gym bag, and protects surrounding gear from snagging. Fasteners stay attached to the frame - no extra straps. Clip closed for storage, then unclip quickly to reopen.
