Dual-function, selectorized core trainer with 20-position ROM control and light-commercial build
Train abdominal crunches and back extensions on one compact, selectorized station. The Body-Solid GCAB-STK uses a full-range cam with an easy pop-pin to give you 20 precise start positions for dialed-in range of motion and control.
A 7-position, fully upholstered leg/foot brace locks in your setup for targeted isolation, while the 30° working angle supports natural, biomechanically correct movement. Ultra-thick DuraFirm™ pads, a 2" × 4" steel mainframe, and smooth commercial hardware make this an ideal pick for home gyms and light-commercial facilities.
