Musclemania® Balkan Champion Blaz Hrastnik holding super mass and condition. The 6'2", 225 lbs., physician says, "In my opinion there are three aspects to conditioning: genetics, training and food. The relationship between those three varies by the individual. I am training around 3 hours a day. My body naturally burns a lot and stores less, and i am very stubborn when i decide to maintain a diet. So all three aspects are fully leaning toward fat burning."
