From April 17 to the 20th I spent training at New York San Da.
I got to experience a wide variety of classes and then had two days of personalized instruction as I was the only one who registered...it was great because I got a private weekend of training but less so because I was drilling and then sparring with a bunch of Ross' fighters.

We covered a ton of material but what I walked away with mostly was not just drills and techniques (although there were piles of these that I am now working on integrating in my program) but the way they are trained, which everyone always harps on, and also the WHY you do X and Z instead of Y. To me this was the biggest benefit of the seminar. Learning technique, going through drills of why you do it, and then, somewhat, trying it out in sparring and seeing how the system flows together.

Aside from the seminar, I also had the opportunity to take some classes with the other guys who were all super friendly and encouraging, and got to see how the material is presented to a large group. Based on this I can say that even if no one takes the seminar, a day, week, month, whatever, of regular classes will benefit anyone. I know that in each segment I gained a new insight into training, technique, and fighting that I consider very valuable.
When presented with questions about specifics, Ross didn't just give me one answer or say to do this, he gave me the worst case scenario, a better one, an even better one, and a drill to insure one doesn't end up there! Ask one question and get four drills that all make sense and work...dayum!
While getting whupped in sparring Ross was telling me more and more things to do and although I proceeded to get whupped some more, I was able to do a few things. He's got an eye that only tons of experience can get you.

I hope at some point to go back and take a week of classes (that's another thing, full time instructors should take notice of the class breakdown and replicate it!) and maybe donate some more blood to the boxing ring.
