I learned some Judo in the military. Not sure how effective it would be up against a well trained Muay Thai style kickboxer however.
Maintaining a good center of gravity and knowing how to apply natural inertia is a force that will render an opponent to a pile of his own vomit in mere seconds.
I would never want to get into a scrap with these boys.. :D
Thanks for sharing :)
