The reason why you're not making back gains at home is because your pull up bar isn't up to par (hint: The Mega Bar has features that will have you making gains in no time).
This ONE bar is pretty much everything you need. (This thing can even be used for curls)!
You never have to worry about wasting your money because it breaks. (Mega Bar is truly a high quality product).
I even use it! (I wouldn't endorse something I didn't use or didn't like. Trust me it's good).
