Aging Celebrities Whose Beach Bodies Defy Time

Reese Witherspoon

Reese Witherspoon (44) is a lot like us when it comes to exercise - she isn't the biggest fan. She still does it, but not to the extremes of other celebs on the list. She does cardio for 30 minutes a day, six days a week. Yoga retreats are her favorite exercise, but she's also known to do Body by Simone workouts a few times a week.

Like many of today's celebrities, Reese Witherspoon thinks that diets should be whole and balanced. It's no longer the '90s when crash diets reigned supreme. She works closely with nutritionist Kimberly Snyder and adores her Glowing Green Smoothie. The smoothie has actually become a celebrity go-to. Reese doesn't restrict any food from her diet, including carbs, which is her self-acclaimed favorite late-night snack.
