Studied Kenpo for a short time many years ago. Considered to be one of the most aggressive or violent forms of martial art, they teach 100% power, 100% speed all the time. These are just as important as technique. I would love to continue but havn't found a school close enough to home.
Both physically and mentally, its the best thing you can do!
I had the luxury of small classes, so i got a lot of one on one work. also had three teachers besides the school director:
his son, which focused on technique,
an older ex-marine, who really tested you physically,
and another guy who focused on practical applications.
and the director, he was about 5 foot tall and a bit overwhieght (looked like Danny Devito) but he could whoop your ass with his pinky and make you like it!:rofl:
