I do it as a therapy. I do it as something to keep me alive. We all need a little discipline. Exercise is my discipline.

On one of my birthdays I did 1,000 chin-ups and 1,000 push-ups. For my 70th birthday I towed 70 boats with 70 people in it, my feet and hands tied-my hands were in handcuffs, my feet were tied together-and I towed these boats a mile-and-a-half in Long Beach Harbor. For my 93rd birthday I'm going to tow my wife across the bathtub.

I'm always asking people to do something in their mind [first]. So if they're gonna do one exercise, it would be to ask themselves what they want to change about themselves in the next 12 weeks. Once they solve that, the body will follow.

What you need to do is get that tape measure out, and start measuring that gut. Then you start working out and you start eating properly till that gut gets down close to it was when you were in your 20's. Then you'll find out what your weight should be.

Develop a positive attitude. Think and picture how amazing you are going to be. Visualize it!

I'd rather take a beating sometimes than get in that gym every morning. Anyone who gets up that early and says he likes it is a goddamned liar. The only good thing about it is that when I'm finished, I look at myself in the mirror and say, "Jack, you've done it again!

Everything in life that's meaningful takes effort - takes vitality. You have to work at it. And God helps them who help themselves...help you.
