Most workouts are way too aggressive. Thousands of lunges wear out the body.

Everyone has a story that makes me stronger. I know that the work I do is important and I enjoy it, but it is nice to hear the feedback of what we do to inspire others.

Our children are obese, either have or being threatened by diabetes, high blood pressure, high cholesterol, and not socially adjusting properly to others because of a lack of fitness.

I've never swayed from who I am. People have seen me on television, and they know what I'm like and they know what I do and they respect me for what I do. They know that I'm huggy and kissy.

Number one, like yourself. Number two, you have to eat healthy. And number three, you've got to squeeze your buns. That's my formula.

When you gain weight, for every pound that you gain, it adds four pounds of stress on your knees. So if you gain five pounds, you've got 20 pounds of stress on your knees. So that's why I'm extremely careful with my portions and my workout, because I can't be overweight.

I'm 64, but I act like I'm still 12. I go to schools. At colleges, they come out in droves, they almost scare me. I think it's just to see if I'm still alive. After I work them out - and it's not easy - I sit them down and we have a serious talk. Are they eating? Working on their body? I can say things parents won't say. No matter where I go, I talk to each one individually after I teach. They tell me things like, 'I'm starving, guys like girls thinner.' I give them concrete advice about self-image and self-worth.
