Hey Josh and Nick, Muay Thai from my experience will not necessarily build you up and make your frame any larger. From what I know of it, and have seen, it will tone you up, and make you definitely more of a Fighter. Its great for self defence in street fights. Its focus’ alot of strikes and kicks, predominately from the elbows, knees, and fists. A well trained Muay Thai artist is an awesome fighter.
