Musclemania® Korea Physique Champion Jun Choi will take the stage in Las Vegas at his MM Pro debut. The 5'8", 175 lbs., Seoul sports model has added 7 lbs. of muscle since competing in last year and with leaner condition. "After last year, I really saw my potential and took all this lifting and dieting more serious," Jun says. "I realize now that the weight and size doesn't matter if the condition is not good. So, I clean my food and it made a big different in my shape and even helped my symmetry appearance."
