First time I did it, I just did it. Didn't really feel that hard and there wasn't much after effects.
What I like and glad my brother threw this into his article, this is a total STFU and do it kind of thing. So, now, we have lots of people giving it a shot.
Gonna watch the numbers. I hope I don't see too many x-fitters posting they did 200-300 reps and did muscle-ups while resting.
