Body-Solid GCBT-STK/3 Pro Select CAM Biceps Triceps Machine 310 lb. Stack

Body-Solid GCBT-STK/3 Pro Select CAM Biceps Triceps Machine 310 lb. Stack, Dual-Function Upper Arm Design, 28-Position Cam Range of Motion, Heavy-Duty Steel Frame

The Body-Solid Pro Select CAM Biceps Triceps Machine (SKU: GCBT-STK/3) is an upgraded commercial-grade dual-function selectorized strength station equipped with a heavy 310 lb weight stack. Engineered to deliver intense upper arm isolation within a single compact footprint, this machine allows users to perform both bicep curls and tricep pressdowns without sacrificing valuable floor space.

Designed around biomechanical precision, the machine features an arm stabilization pad positioned at an optimal 30-degree angle to maintain proper joint alignment and remove uncomfortable pressure from the elbows. The bicep curl pivot automatically rotates to match individual forearm lengths, virtually eliminating wrist strain. For tricep extensions, the multi-grip V-bar handle supports both overhand and underhand grip orientations to isolate different heads of the triceps.

Built with heavy-duty 2" x 2" and 2" x 4" high-tensile steel frame tubing, the GCBT-STK/3 is structured to endure rigorous daily commercial gym use. It features a 7-position adjustable seat and a 28-hole range-of-motion adjustment cam for complete control over starting positions. This model comes fitted with the upgraded 310 lb (141 kg) selectorized weight stack and thick, moisture-resistant DuraFirm™ upholstery for maximum durability and support during heavy lifting sets.
