Pro Clubline S2AC/2 Arm Curl Machine 235 lb. Stack, Focused Bicep Isolation

Pro Clubline S2AC/2 Arm Curl Machine, Heavy 235 lb. Weight Stack Upgrade, Contoured Arm Platform, 6-Position Seat Adjustment

The Body-Solid Pro Clubline Series II S2ACX Arm Curl Machine (SKU: S2AC/2) is a full commercial-grade selectorized strength training machine equipped with an upgraded 235 lb heavy weight stack. Engineered specifically for intense, targeted bicep development, this machine delivers a smooth, biomechanically precise curling motion designed to maximize muscle engagement while eliminating stress on the wrists, elbows, and back.

Featuring an advanced variable-resistance cam, the S2ACX maintains consistent resistance throughout the entire arc of movement, ensuring maximum peak contraction at the top of the curl. The ergonomically contoured arm pad stabilizes the upper arms and aligns the user's elbows precisely with the rotational axis of the machine. The multi-grip revolving handlebar self-adjusts during the exercise to allow full high- and low-contraction phases, targeting the biceps from multiple angles.

Constructed from heavy-gauge 2" x 3" 12-gauge steel with 4-sided continuous welded frame construction, the S2ACX provides unyielding stability under heavy loads. A 6-position gas-assisted adjustable seat accommodates users of all heights, while extra-thick DuraFirm™ padding ensures optimal body support and comfort. The upgraded 235 lb weight stack is completely enclosed in a protective steel shroud for enhanced safety and a refined commercial appearance.
