I took a very watered down American kickboxing class which I didn't get a thing out of. I blame this more on a lousy instructor than the art itself. Other than that I have little experience in striking. Then I started taking BJJ and realized that this system was far more intricate and that even after over a year of training I'm still just scratching the surface and barely consider myself a novice. I'm interested in Muay Thai, but want to know if it is as complex as BJJ or if one can learn all there is to know of it a lot sooner.
