Most people don't understand what kind of life Bernard leads, it's not just for training camps he trains hard, dude doesn't drink alcohol, doesn't drink pop, won't eat junk/fast food. He has a 28" waist and is never out of shape ever! Goes to bed early every day. Compare that to at least one of those fighters on the list who drinks beers and gambles late night.
exactly That's a stupid slim waist. I didn't even know guys his size can have waists that trim. I'm far from Bernard's height and not fat at all, but my waist is bigger.
Impossible question to answer because some might train for power and explosiveness while others for precision and endurance.
