Ask the guys who are doing serious triathlons if there are any limits to what can be done. The limit is right here. You've got to get physically fit between the ears. Muscles don't know anything. They have to be taught.

Remember this: your body is your slave; it works for you.

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.

So many older people, they just sit around all day long and they don't get any exercise. Their muscles atrophy, and they lose their strength, their energy and vitality by inactivity.

I train like I'm training for the Olympics or for a Mr. America contest, the way I've always trained my whole life. You see, life is a battlefield. Life is survival of the fittest... How many healthy people do you know? How many happy people do you know? Think about it. People work at dying, they don't work at living. My workout is my obligation to life. It's my tranquilizer. It's part of the way I tell the truth--and telling the truth is what's kept me going all these years.

I say stick with Mother Nature as much as possible.

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.
