I don't know that I'll ever get to the point where I can do this kind of shit, but I'm going to try!
P.S. On a semi-related note, I have now gotten to the point where I can do ten pull-ups, both overhand and underhand. I have been able to do ten underhand ones for a while, but the overhand ones are a bit harder. I finally got it though! Next step- salmon ladder.
