“I don't want to lose my fitness. I'm 45. I have two babies. I've got a...” — Marcia Cross Quote

I don't want to lose my fitness. I'm 45. I have two babies. I've got a long way to go and I want to keep in tiptop shape. There's no magic bullet.

I use as high SPF as I can get, and I live under a hat like a mushroom all the time. Someone said they're worried about their kids getting older and doing drugs, and I got this look of horror on my face and thought, 'What if my girls don't wear hats?' But at 13 months old, they could say 'hat.'

I'll tell you my routine - it's really exciting. I feed, I burp, I change diapers, I pump. And then I have a tiny window of time to myself.

I'd never say no to surgery in the future, because I feel like, as I get older, I'm going to face temptation more.

So I've broadened the fitness concept to make it one of moderation and balance.

For whatever reason, maybe it's because of my story, but people associate Livestrong with exercise and physical fitness, health and lifestyle choices like that.

Fitness is the key. You need to have strokes and stamina and agility; you need to exercise really well. On-court and off-court are equally important.

Kids are starting at such a low base rate in terms of fitness that it's taking them years to catch up to where people like me started from. Every little bit is making it more difficult for kids to succeed on a world stage.
