Derek is a 32-year-old martial arts instructor with a whole lot of muscle! Watching him round house kick the punching bag, I have to say that I was both scared and impressed at the amount of power and control he exhibited over his body. However, like most martial artists, he is dedicated to the study of perfecting the bodys skill and discipline rather than using the training for actual fighting.
