Most of us, after watching the guys from Barstarzz do amazing pull-ups, muscle-ups and other very-hard-to-do exercises, aspire to be like them. Even professional fighters, known for their training, struggle to keep up. Some people need years of training but everyone has to start somewhere. We think one of the best places to start is at home. Get a pull-up bar for your door like the Iron Gym. It is one of the most popular pull-up bar that you can easily install on your door frame without tools or fasteners. It's also a dip bar, a push-up bar and can be used for sit-ups and crunches. Just be sure your doorway is 24″ to 32″ wide.
