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.

If man made it, don't eat it.

I say stick with Mother Nature as much as possible.

Have you seen some of the crap they're selling as exercise equipment now? How about that Suzanne Somers? She should have been thrown in jail for selling the piece-of-crap Thigh Master. It just develops a little muscle on the inner thigh. What good is that?

There are so many health nuts out there who eat nothing but natural foods but they don't exercise and they look terrible. Then there are other people who exercise like a son-of-a-gun but eat a lot of junk... Exercise is king. Nutrition is queen. Put them together and you've got a kingdom.

Muscle cells strengthen in response to intense exercise - whether you're 18 or 88. But the intensity is what's lacking in most people's workouts. And there are doctors who'll give you the advice, "Well, don't push it."

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.
