Two core motions in one guided machine—the Pro Dual Ab & Back (DABBSF) allows abdominal crunches and lower-back extensions from a single seated position. The roller pad and pivot arm guide each exercise path without requiring bench repositioning. Built with commercial-grade materials, it is designed for long-term use in both home and facility environments.
Dual-action oversized 9″ roller pad
Adjusts to allow transitions between crunch and extension without complicated repositioning.
Gas-assisted, five-position seat
Seat adjusts to align the pivot point with different torso angles.
Leg pad with six height settings A leg and foot brace that accommodates a wide range of users—keeping your base stable for every motion
Counterbalanced resistance arm with 14 angles
Provides an adjustable arc of motion with 14 starting positions.
210 lb weight stack (optional 310 lb upgrade) Allows for progressive resistance without changing plates mid-workout
Modern curved, powder-coated frame Elegant styling that’s easy to clean, with continuous-weld framing built for modular gym systems
Built for durability in busy environments
Sealed industrial bearings, fiberglass-reinforced pulleys, aircraft-rated cable, and DuraFirm padding are designed for frequent use.
The DABBSF is intuitive: just sit, adjust the seat and leg pad as needed, select your cam angle, and begin. The oversized 9″ roller pad provides torso support during crunch and back-extension movements. Adjustment labels and pin stops are visible while seated, allowing users to transition between movements or change settings without leaving the machine.
