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.

I hope in my lifetime we can all continue to laugh at ourselves and not put down anyone for what they weigh.

I spent my childhood eating. The only exercise I got was trying to twist off the cap of a jar of mayonnaise.

I really created my career out of my own compulsion. Because I knew if I owned an exercise studio and I had to teach my classes there, I wasn't going to gain my weight back.

Well mine is not gimmicky - it is the 6 food groups that God made, and exercising every day. Trying to think positively.

I don't know about you, but every time some joker points me out as I walk through an airport wearing extra-small Dolfin shorts, a tank top and leg warmers, I get a little upset.

Sleep is critical to me ... at least eight or nine hours a night. I start to slow down my body and my mind at least 30 minutes before I get into bed. I don't watch any disturbing or invigorating TV at night.
