The Door Gym stands head and shoulders above the competition. This versatile device can be set up in seconds on almost any door frame and lets you work out in the convenience of your own home or office. It latches on without screws, bolts or fasteners, so you won't leave holes in your door trim. A cantilever design uses your own body weight (up to 300 lbs.) to keep it in place. Door Gym is more than a simple pull-up, chin-up bar. It also has two protruding close-grip handles that let you work out with your palms facing each other, a good position for isolating the muscles in the center of your back that control posture. In addition, you can use Door Gym on the ground as a push-up bar and a sit-up spotter.
