I have already gone thru the MU progressions 8 years ago. A muscle up is just something i get up on the rings and show kids every now and then for fun. I'm gonna opt out of all of that negative this and false grip that and just work on the actual rMU and harder MU variations until R2 comes out. Can anyone give me a good reason to do the progressions? There isn't even any mobility to go with it other than the already Rx'd mobility that you do every time.
My workout till R2
5x5 wide arm MU
Neg rMU
5x10s
