This is a very cool and simple way to install an exercise bar in your house but you need to be sure that you have an appropriate door frame.
The Iron Gym–whose durable steel frame installs quickly without tools or fasteners–holds up to 300 pounds and is designed to fit residential doorways 24 to 32 inches wide, with doorway trim or molding up to 3.5 inches wide.
And a quote from an unsatisfied Amazon.com customer:
For this item to work properly, you’ll want to make sure your door frame is between 5.5 and 6 inches thick.
- Ideal for pull-ups, push-ups, chin-ups, dips, crunches, and more
- Three grip positions, narrow, wide, and neutral
- Uses leverage to hold against the doorway so there are no screws and no damage to door. Installs in seconds.
