How the Stars Stay in Shape Through the Holidays

Dec. 6, 2010 — -- Most of us regular folks get through the holiday season one gingerbread man at a time (well OK, maybe more than one). But the stars? Their workout routines break for no celebration.

Just in time for the spate of baked hams and fruit cakes, a slew of celebrities are speaking out about how they stay in fighting shape, no matter the time of year. Below, check out their tips, put them to use and be able to button your pants come January:

Jane Fonda

She may be 72 years old, but nothing's slowing down Jane Fonda. While most of America was nursing a lingering turkey coma Nov. 30, Fonda put out two new fitness DVDs -- "Jane Fonda: Prime Time Walkout" and "Jane Fonda: Prime Time Fit & Strong." Both are targeted at the baby boomers who sweat it out to Fonda's first uber-successful fitness video, "Jane Fonda's Workout." "I'm very excited to be back in the fitness business," Fonda told People magazine about the "Prime Time" series. Before these DVDs, she hadn't released a new workout program since 1995. "I know from experience and from my research how critical it is for boomers and seniors to be physically active. Even if they've never exercised in their lives, now's the time, and my programs are a good, safe way to do it."

Christie Brinkley

Christie Brinkely keeps her body in top form with her Total Gym system. But when the 56-year-old supermodel and mom of three can't fit in a full workout, she turns everyday routines into toning sessions to get the job done. If she has to blow dry her blond locks, she does so in a squat position. When she's brushing her teeth, she's also toning her tush. Brinkely recently told Shape.com, "I'll dry my hair as though I'm sitting on a chair, even though there's no chair there." She continued, "When I am brushing my teeth, I'm bending my leg behind me, or I'm lifting my leg up and holding it in that position so I'm squeezing my butt in. I can do that while I'm washing or slicing vegetables, too. Or I go up and down on my toes, working my calves a little bit."
