Coach Mark's Notes:
The muscle-up is an invaluable motion. Learn it, practice it, and make it yours. 99% of the time, those that aren't getting it are just not strong enough. Do your heavy days, and master the CTB pull-up and the ring dip. If you can do 15 good CTB pull-ups and 15 good ring dips, you probably have a muscle up in you. It's one of the motions that separates the good from the better. Get pulling!
