By exercise. I'll tell you one thing, you don't always have to be on the go. I sit around a lot, I read a lot, and I do watch television. But I also work out for two hours every day of my life, even when I'm on the road.

That is the beautiful part about weights: even if you are 100 year old, you can lift something. Maybe it's only a half a pound or a pound or two pounds. It will still do something.

Look at the average American diet: ice cream, butter, cheese, whole milk, all this fat. People don't realize how much of this stuff you get by the end of the day. High blood pressure is from all this high-fat eating.

The brain's preferred source of fuel is glucose/carbohydrates. And when you go on a low-carb/high-protein diet, your brain is using low-octane fuel. You'll be a little groggy, a little grumpy.

Physical fitness takes commitment to exercise just as it requires good nutrition. But it doesn't have to be painful. Just the opposite: Vigorous exercise actually is stimulating. It boosts your energy levels, invigorates your mind, and just feels good afterward. The hardest part, of course, is getting started.

Thoughts are things. Negativity is what kills you... It's tough to do, but you've got to work at living, you know? Most people work at dying, but anybody can die; the easiest thing on this earth is to die. But to live takes guts; it takes energy, vitality, it takes thought. . . . We have so many negative influences out there that are pulling us down. . . . You've got to be strong to overcome these adversities . . . that's why I never stop.

Exercise is your king, and nutrition is your queen. Together they create your fitness kingdom.
