I 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.
