BOMB PROOF® Selectorized Abdominal Crunch / Lower Back Extension Machine - The BP-110 is an American Made core training machine that includes abdominal crunch capability for training the anterior core as well as a low back extension for the posterior core. Combining both an ab crunch and a back extension in one single selectorized machine offers a reduced footprint and much smaller financial investment when compared to buying two separate machines that offer the same result. An ab crunch / back extension combo machine that performs well in a commercial environment starts with a solid frame. The BP-110 combines 2 x 2 x 11 gauge mig-welded steel tubing with high grade hardware for a solid feel under the size and weight of any user. The seat pad and rollers are constructed using only 2 thick high density neoprene foam padding that offers plenty of support and holds its shape year after year. The 200 lb. weight stack is adjustable in 10 lb. increments and is driven by two polished steel guide rods, 2,000 lb. capacity cable and high quality pulley wheels that have sealed ball bearings for the smoothest rotation. Changing from an ab crunch to a lower back extension is quick and easy thanks to the pop-pin design. And the shin rollers and diamond plate foot plate offer stability and comfort while performing either exercise. You can also choose your favorite powder coat and vinyl colors per the drop down menu at no extra charge. Need custom colors to match existing equipment?
