*Updated Black Frame*
The GCAB360 provides guided motion for both abdominal and lower-back exercises in a single compact unit. Suitable for home gyms or commercial facilities, it features adjustable movement paths and a durable steel frame.
Two Movements in One Station Easily shift between forward abdominal crunches and backward extensions—all without stepping off the seat. Just reverse your motion direction to switch functions.
Cam-Driven Resistance System
The cam arm moves along a fixed arc designed to deliver consistent resistance throughout the range of motion.
26-Position Adjustable Pivot Arm A simple pop-pin allows you to adjust the lift arm for the most ergonomic angle, tailored to different leg lengths or mobility ranges.
Steel Frame Built for Daily Use The 2" × 4" 11-gauge steel construction stands up to light commercial use without occupying much floor space.
Ergonomic Seat and Padding
The seat is upholstered with thick DuraFirm foam. It tilts forward at 18°, and the frame is angled at 30°.
Compact Footprint At less than 80 lb and measuring roughly 59" long × 45" wide × 43" tall, the machine is space-efficient and suitable for smaller rooms and garage setups.
Getting started is simple—sit down, place your feet against the brace, load your plates, select the pivot angle, and begin. The dual-action cam accommodates both crunch and extension movements with no need to stand or swap settings. The pop-pin arm adjustment and grips allow users to set up the machine to match their height and range of motion. The cam design provides a consistent arc of movement for both crunches and extensions.
