I found that to build mental toughness, you need to inconvenience yourself. The early morning runs, if you hate early mornings. The late night runs, if you hate late nights. The snowy cold, the worst conditions you can get, put yourself in those and really make it inconvenient and you start to get a genuine expectation of winning for the price you have to pay.
Chael SonnenI go to practice each and every day, but my intensity is not the same. If I get tired, I'll go sit down. If I want some water, I'll go drink it. When I'm in training camp, I don't. I've got to push through being tired. I've got to push through being uncomfortable. That's really it. It's largely a mentality. You kind of flip that switch and turn your intensity up. Your heart rate goes up. Your reps go up. And you start to get in the frame of mind.
Chael SonnenMy phone rings, they call me up and say, 'Chael, your testosterone level is too high.' I say, 'Well, how high was it?' They say, '0.7.' I said, 'What's normal?' They say, '0.6.'; I said, 'One-tenth? You're telling me I'm one-tenth higher than the average man? Re-test that - you must have caught me on a low day.'
