Strengthen your back, chest, biceps, shoulders, abs, and more in the comfort of your living room or dorm with the Iron Gym Extreme Edition workout bar. An upgraded version of the original Iron Gym, the Extreme Edition boasts two additional grip positions for a total of five: the default narrow, neutral, and wide positions of the first Iron Gym, plus alternate wide and side grips. When installed in the doorway, the device lets you perform pull-ups and chin-ups, with several options for working the inner and outer back. Once you're done with your back workout, you can quickly move the Iron Gym to the floor, where you can perform pushups while facing down, tricep dips while facing the other way, or sit-ups using the Iron Gym for foot stability. The Iron Gym is the ultimate workout tool for people who want to shape their upper bodies and tone their midsections. And unlike many other workout bars, the Extreme Edition installs conveniently in most doorway frames without damaging your walls or doors with a permanent installation. Just take it off the door when you're finished--no harm done. Sporting a durable steel frame, the Iron Gym Extreme Edition holds up to 300 pounds and is designed to fit residential doorways between 24 to 32 inches, with trim or moulding up to 3.5 inches wide.
