We all know Courteney Cox Arquette is beautiful. She's a former model and once landed on the cover of People magazine's Most Beautiful People issue. But what might surprise you is that even a stunner like Cox Arquette is feeling the effects of time marching on. So what does she do to fight Father Time? She exercises.

Cox Arquette isn't unrealistic about her looks. She said, "People who read a magazine can look at the picture and go, 'She looks great for over 40!' But guess what? That's not what I look like. Lighting is everything. When you're in your car and you look in the mirror and the sun's beaming in, you're like, 'Wow, times are getting tough.'" Personally, I think it's refreshing to hear celebs state the problems we all have. I certainly don't have make-up artists and professional photographers snapping shots of me -- but I know I've had days when things looked pretty good in my bathroom mirror, but then all the age lines and pores showed up in the light of day.

Cox Arquette fights back against the natural signs of age with cardio and weight-training five times a week. She enjoys running, hiking, and doing total-body exercises.
