What are you looking for?
S&C or skill training?
Each of them are pretty distinct in some ways.. well at least skill training is more towards working the various skills. S&C does have some skill components that are extremely important to develop like all kinds of press handstands and such things, but may not always be developing skill components rather flexibility and strength for stuff like on rings.. and then conditioning for doing their 4+ hours practices.
There's tons of stuff currently out on skill techniques even in books. Just gotta find them. Not so much on the S&C aspect of it which is more of what Coach Sommer's stuff is getting towards.
