When I first started aikido, it was a real eye opener for me as it convinced me about how effective this martial art is without using a lot of physical strength that is ever present in most other martial arts.
Mal has shown how soft you need to be as well as how devastating aikido is at a high level
I have not looked back since and I would encourage anybody with a martial art background or an interest in martial arts to give it a try. You will be amazed.
