My son has started taking kalari-payattu classes and I have been seeing some significant changes in him physically and emotionally.
He had tried other martial arts before but didn't really enjoy them. He is really enjoying kalari-payattu though and I'm so happy about that.
I think kalari-payattu is not as rigid as some of the other Asian martial art techniques. Speed and discipline is just as important, but kalari-payattu also does a lot for physical flexibility and concentration. My son can do moves I've never seen before, his legs and upper body is so flexible and his body has really toned up. His teacher has also said that he is doing better at school concentration wise.
I think more kalari-payattu classes need to open up in the U.S., it's an excellent pass time and hobby for youngsters.
