WTF are you talking about??? Are you suggesting he just ate and drank a gallon of water before goin out to pose 
no, but guys stay very hydrated in the offseason and are very empty onstage when they compete. If it was one of D_minus' first guest posings, maybe he wasn't aware of the need to pop a diuretic before getting up there. Or sucking in his belly, as the first pic of him exhaling will be pwning him on message boards for the next 40 years.
His lines, shape, genetics, completely pwn a seasoned pro like Branch, and he's 4 weeks out from a very stressful show, with the pressure of being a MD cover boy in NYC all weighing on him.
That being said, he NEEDS to get the gyno fixed and learn to control that belly.
