My teacher is Tim Cartmell.
Undeniably a great, and knowledgeable internal master. Also undeniably a very formidable MMA, and Jiujutsu competitor.
Internal isn't so mystical. Good football players have great internal skills. So do Gymnasts, Tennis players, Baseball players, Track and field men etc. etc.
I don't think that statement is slamming anyone. I just don't think internal power is as hard to get as the rest of you.
No one would doubt that Tim is a gifted MAist.
I've never met him, but he does talk about some pretty good concepts that overlap.
But what you just said kind of shows your ignorance on these matters. Sure some athletes, football players etc have internal "components" that are needed in order to do the internal "skills", but that doesn't make them "internally skilled"
No one has said that internal skills is mystical either, but it does have to be specifically taught.
Just curious, asides from Tim, who else have you had hands on time with that's generally accepted as having "great" internal skills?
