I'm not surprised about Lesnar. He was training way too hard. Working with tons of different people. He trains with an olympic wrestling squad. Thats all he does. Eat, sleep, train, rest, repeat, with a little hunting thrown in for good measure. No one can argue that before he got sick, he was the best heavyweight MMA fighter in the world. Way better than Fedor. Brock walks around at 290 lbs and its pure muscle. Then he cuts to 265 for his fights. Not the healthiest way to live but god damn he's a beast.
