The SFE Selectorized Back and Ab Combo Machine is a dual-function commercial-grade machine that trains both the abdominals and the lower back from a single station. The 250lb selectorized stack runs at a true 1:1 pull ratio for honest progressive overload.

An adjustable range of motion lets users transition between back extension and abdominal crunch movements without leaving the station. Ergonomic padding and a commercial-grade frame keep heavy sets stable and comfortable.

Training the back and front of the core in proportion is associated with improved spinal stability and reduced lower-back tension. The dual-function design makes balanced core training fast, efficient, and consistent.

If you want one station that delivers balanced core development without rotating between separate machines, this combo is built for that.
