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.

Focus on your problem zones, your strength, your energy, your flexibility and all the rest.

Most people, when they reach a certain age, let down and talk about what they used to do. Well, who gives a damn about what you used to do? It's what you're doing now.

Who puts the food in your mouth? Who goes to the bathroom for ya? You do. You came on this earth alone and you are going to leave alone. Think about it. If anything happens to Jack La Lanne good or bad, I made it happen. If anything happens to you good or bad, you made it happen - right?

Invest in yourself now and reap the dividends day after day after month after year.

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