Weee, I made a thing! Of course if you don't know how to do a pullup or pushup, or if you don't know what I mean by rotations, you will need a trainer. But stuff that you find on the internet is just a starting point and not the be-all end-all, you know that right?
I'm mostly super excited about this because training pullups can be challenging sometimes, well, because pullups are challenging, but also because sometimes it's hard to find a place to hang from. Where oh where could you hang from.
