But unlike Karate, Muay Thai does okay as a purely physical thing. You will never be good at Karate the way it's supposed to be done unless you fully understand the mental application. That's why most karateka in this country couldn't hold off Richard Simmons if their lives depended on it. The powerful, solid, and potentially lethal techniques you see in kata won't come naturally, like so many of Muay Thai's. They must be practiced and drilled into your mind and muslces, and applied properly, something which takes a high level of mental/spiritual practice. In case you haven't noticed, most mcdojos don't specialize in intense mental/spiritual practice.
