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.

Twelve to seventeen minutes is plenty on the treadmill--if it's done fast. That's all you need for cardiovascular benefit. You don't need to spend that extra time unless you are over weight and you need to burn off extra calories. Do it vigorously, like somebody is chasing you. You've got to do it hard. Otherwise, if you just take it easy and do it longer, you are spending all that time when you don't need it. Use that extra time with your weights instead.

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.

Be an example of what you teach. [As a personal trainer], delve into your student's life, know everything about him. Be interested.

Never, ever get satisfied; keep the carrot in front of the horse.

All athletes would be better if they eat better. Junk in equals Junk out.

If you're tired and pooped out all the time, do you have love and compassion in your heart for your fellow man? You don't even like yourself!
