Description

Body-Solid (#GCAB-STK) Pro Select Ab And Back Machine

A seated station for core training in a compact design.

The GCAB-STK Pro-Select by Body-Solid combines guided movement and adjustable settings into one unit. Suitable for both home setups and light commercial use, it supports abdominal and lower-back exercises from the same seated position.


Key Features That Matter

  • Single station, dual focus
    You can work your abs and lower back by simply reversing your seated motion—no complicated re-positioning or equipment swapping required.

  • Cam-guided resistance with 20 angle settings
    The pop-pin cam offers twenty selectable arm positions, allowing you to tailor the path to fit your range of motion or flexibility level.

  • Seven-position leg pad brace
    Adjustable foot brace isolates your lower body while you move through a full range of motion for both crunches and extensions.

  • Ergonomic, durable padding
    The contoured seat and back pads are upholstered in thick DuraFirm foam designed for repeated use and durability.

  • Commercial-grade steel frame
    Built on 2" × 4" 11-gauge steel tubing and precision-welded for stability and durability. Despite its rugged build, it fits into tighter spaces.


User Interface & Experience

The GCAB-STK allows core exercises from a fixed seated position. Load standard 1″ plates (Olympic adapter optional), adjust the seat and leg pad, and select the cam angle. The resistance arm moves on a 30° arc, and the seat is angled at 18°. Adjustment points are labeled and accessible while seated.
