Huge 6'4" (1.93m) bodybuilder Big Sean Allen at the 2012 Masters Mr. Olympia finals in Miami Beach, Florida.  You can see a lot more buff guys his size in my Bodybuilding section. He is about 285 lbs. here.  When gaining weight off stage he can grow to up to 350 lbs. but found that left him feeling too bloated.  He has been up to 320 lbs. with less than ten percent body fat and yet his waist rarely gets wider than 33".  He has a 68" chest which is absolutely gigantic.
