just like no MMA fighter can walk onto the Olympia stage and even place, a bodybuilder trains for cosmetic purposes not to fight,im not saying they cant fight cause I know a few that can kick ass. a lot of guys think ALL bodybuilders are just musclebound and have no cardio but these days a lot of guys r cross training in both so its hard to tell.i know dudes that look like bodybuilders that r animals in a fight with great cardio,i learned at a young age u cant under estimate anyone,whether they r skinny,musculer,fat ect,it means nothing and a lot of people can be in for a reude awakening doing so
