Body-Solid GCAB-STK Ab & Back Machine
The Body-Solid GCAB-STK Pro Select Ab & Back Machine is a dual-function commercial-grade unit that combines abdominal crunches and back extensions into a single piece of equipment. Built around a 2x4" heavy-gauge steel mainframe and a 30° movement angle engineered for proper form, the GCAB-STK delivers comprehensive core development from one machine — useful when floor space is at a premium and a facility still needs both movements covered.
Key Features and Benefits
The 30° movement angle is the key biomechanic on this machine — it positions users for proper form on both the abdominal crunch and the back extension, ensuring full muscle engagement without compromising on safety or alignment. A 7-position adjustable leg brace accommodates users of varying heights, while the 20-position pop-pin cam system delivers a customized range of motion for each user.
The 2x4" heavy-gauge steel mainframe and ultra-thick DuraFirm upholstery handle the demands of continuous commercial use. The machine is offered with a choice of 210 lb or 310 lb selectorized weight stack, sizing the resistance to the facility — light-use studios can run the 210, while higher-traffic commercial gyms can step up to the 310.
The GCAB-STK is part of Body-Solid's Pro Select line of commercial machines, designed to combine two related exercises into one footprint without compromising the quality of either movement. The dual-function design saves floor space, reduces equipment count, and keeps users training instead of waiting for separate machines to free up.
