The TAPS Bar is the mobile pull up bar of choice for Kettlebell Enthusiasts, Crossfitters, and Military Personnel. The bar breaks down and is easily moved and re-assembled in about 5 minutes. It is also very sturdy and is adjustable from 5-9 feet. Often when people see the price tag on a quality pull up bar they balk. Yet they are willing to spend hundreds of dollars on shoes and other things that will not stand the test of time nearly as well as this bar. In terms of strength development consider that if I could only do two things they would be pull ups and military presses. Right now that is the bulk of what I do, and my upper body is strong enough from it to bend a horseshoe. Look around the Torque pull up bar section and you'll also find a number of more inexpensive doorframe style bars.
