Haven't even tried. I started PBF a few months ago, and due to some health issues, only completed two weeks worth. I just skipped the pull up section, thinking I would get a bar later and work up to it.
I did go shopping today trying to find a pull up bar that seemed sturdy and affordable. There is one more sports equipment store I want to hit tomorrow, then I will make my decision and get one.
Honestly, I have the upper body strength of a 3-year-old, so I may be the last one of the group to accomplish the goal. But I WILL get there.
