Jane Fonda credits a healthy low-carb diet and regular exercise for her age-defying good looks at 77, Celebrity Health reported.
"I believe in fitness," said Fonda. "Whether you're young, whether you're old, whether you've been exercising or just starting. It's maybe the most important thing in having a successful, long life."
Jane credits regular workouts for helping her overcome depression, the early suicide of her mother, bulimia, anorexia, three divorces, and breast cancer.
"The fact that I have always remained physically active has had a great deal to do with [staying sane]," said Fonda. "It has kept me centered and balanced emotionally. I also meditate, and I have a very strong social network. Maintaining physical fitness and social networks is so critical to successful aging."
Jane has released 23 best-selling fitness DVDs since 1982. Fonda revealed her workout secrets in her latest exercise video, Jane Fonda Prime Time: Firm & Burn Low Impact Cardio.
Fonda, who battled anorexia, bulimia and poor body image during her 20, 30s and 40s, has adopted a more laid-back approach to fitness now, and follows a healthy diet featuring lots of vegetables and lean proteins.
Jane has admitted to several plastic surgeries through the years. She had a facelift in her 40s and another one in February 2010. She also got breast implants when she was younger and recently had a chin lift as well as plastic surgery to remove the bags under her eyes.
As she has gotten older, Fonda has transitioned away from the rigorous, high-impact aerobic exercise she extolled during the 1980s to gentler, lower-impact workouts. Fonda does yoga, strength-trains, walks, cycles, and uses the elliptical trainer.
Jane, who has an artificial hip and titanium knee, said being an avid exerciser all her life has paid off — both physically and psychologically.
"If you're in the middle of a nervous breakdown, working out really hard is not a bad thing because it does keep you from going over the edge," she said. "It gets the endorphins going. And it's kind of like 'I'm sore, so I must exist.' It makes all the difference in the world."
While most people dread getting older, Fonda embraces it. She shares her views on fitness, aging, and happiness in her memoir, Prime Time: Love, Health, Sex, Fitness, Friendship, Spirit: Making the Most of All of Your Life.
