Dual-function, selectorized arm machine with 28 start positions, 7-position seat, and commercial-duty frame — ideal for HOME GYM OWNERS and LIGHT COMMERCIAL
The Body-Solid GCBT-STK delivers two premium arm stations in one compact footprint. An intelligent cam design and a rotating V-bar handle let you switch seamlessly between biceps curls and triceps pressdowns by simply repositioning the lifting arm. The arm pad’s 30° angle supports precise joint alignment without elbow pressure, while the curl mechanism pivots and rotates to match forearm length and reduce wrist stress.
Dial in perfect mechanics with a 7-position gas-assist seat and 28 distinct start positions for full range of motion. Ultra-thick DuraFirm™ upholstery, 2" × 2" and 2" × 4" steel construction, and smooth, commercial-grade pulleys make this a durable, quiet addition to any serious training space.
Dual-Function Cam System
Pull the large pop-pin to lower the lifting arm for biceps curls, or raise and lock it for triceps pressdowns — smooth, repeatable transitions in seconds.
Rotating Curl Mechanism
The curl assembly pivots and rotates to match forearm length, maintaining neutral wrist alignment and reducing unnecessary strain.
30° Arm Stabilization Pad
Angled pad aligns the shoulder-elbow-wrist path for efficient loading without digging into the elbow.

Set precise start/stop points and seat height to target strength through a full, comfortable range.
