Get some, and then get some more.  Just put in the Studbar Pullup Bar and have been working on my pullups.  Yup, I continue to be a fitness geek.  This bar is awesome.  The rafters in my garage are 2x4s so I may sister them up just to make me feel a little better about not pulling down the roof when I’m using it, but it generally feels pretty solid.  The crossbar itself has a little flex to it, which is also good. 

Of course, we all gave it a try — and have the sore hands to prove it.
