"My gym is going to be offering two martial art forms (doesn't say what) but the instructor has been in MA for 30 years and he is very intense (he's also a personal trainer - one of the few I would work with). I'm mostly interested in the ability to focus - can anybody talk about that? Also, how does MA help your cycling? Your day to day life?"

What a lot of questions and so little time on my coffee break but let me dig in.

First, there's a huge diff between a personal trainer and a martial arts sesei and while I'm sure this guy/gal is great I suggest you check out a lot of classes in your area before deciding on a style/instructor.

I'll continue with things to look for and things to avoid when I get my next break ;-)
