If you got 30 reps on the max set you should start this somewhere between 6-8. A pretty butterfly kip does not involve the psychotic flailing you see out the majority of crossfitters. Clean it up! Legs together, don’t break at the knee and send your feet way behind you. Also try to work on fluidity. We saw a lot of people holding on too long on the decent and eventually pumping out because of it. We will be adding a rep each week for a while so don’t bite too much off week 1. This is skill work, not volume work.
