BOMB PROOF® Double Ladder Bent Knee Sit-Up Bench - The BP-35-37 American Made Double Ladder Bent Knee Sit-Up Board by Bomb Proof is built for abdominal and oblique training in commercial gyms. Included is a double-wide four-bar ladder capable of connecting two sit-up benches simultaneously for additional space savings. The included bench hooks onto each of the four ladder bars and offers 4, 11, 19 and 27 degrees of decline for different ab training resistance levels. The V-bench design of the BP-35-37 adds increased support to the legs and reduces the strain on the ankles compared to regular sit-up boards. Oversized foot rollers are included to keep the user locked and loaded and are padded with high density padding to hold their shape and properly distribute the users weight throughout the foot and ankle. For added stability and longevity, the double ladder sit-up board is fabricated from 2 x 2 x 11 gauge steel tubing that is available in four scratch resistant powder coat colors. The 29 oz marine grade vinyl is hard wearing, resists mold and mildew and is easy to clean. Choose between six custom upholstery colors. Need to match your existing equipment colors?
