Yes, exercise is the catalyst. That's what makes everything happen: your digestion, your elimination, your sex life, your skin, hair, everything about you depends on circulation. And how do you increase circulation?

Don't talk age! Age has nothing to do with it. One of my guys who started out at my gym is 87 now, and he still does ten bench-press reps with a hundred-pound dumbbell in each hand. He's training to set a leg-pressing record. I put things in the guy's brain way back when, and now he'll never get away from it.

Progress is made where progress is measured.

Never get satisfied. The minute you stop trying, you go downhill.

Be young. Keep yourself young by having a good, sporty car like a Corvette. It keeps you on your toes. It keeps you young. It keeps you thinking young. It keeps you thinking modern and good things. Corvette is a modern, modern automobile.

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.

People will set a New Year's resolution: "I'm gonna get in shape this year." But they don't set a parameter for how they're gonna measure it. Or if they do measure it, they wait until the first day of the next year. You'd never run a business that way. Document your progress.
