This Vertical Knee Raise, Dip, Pull Up machine is geared toward an intense ab workout for serious gym junkies. Healthier for the lower back than simple floor crunches and sit-ups, this machine uses gravity to protect back muscles and build abdominal strength. A simple step up makes for an easy position to get into, and the DuraFirm back pads and arm supports are comfortable on the upper body while you focus on your core. Great for the obliques in particular, but also offers a good solid workout for the triceps, deltoids and lower pecs. The heavy-gauge steel frame construction with 4-side welding means you are supported and secure in this machine.
