You should do it against the clock. Say you are going to do 30 laps in 15 minutes. Then you try to do it each day a little faster. That is putting demands on the body, and that is how you build up. You keep up your energy instead of going downhill.

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

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

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.

You got to do what's happening today in the world. You got to keep up with time. Keep up to date, keep modern - keep up on your toes!

I believe so strongly in what I do and I practice what I preach! My Dad died at fifty - do I have to die at fifty? My Dad ate all the junk food, he wouldn't exercise - how can you tell your Dad anything? We know about nutrition and we know about exercise. There's no reason for anybody to be sick and tired, fat and out of shape - it's ridiculous!

One of the reasons so many people fail is they get on this treadmill for an hour or an hour and a half. That's totally unnecessary. If it's cardiovascular, you don't need more than 15 to 17 or 18 minutes if it's vigorous.
