Age is clearly just a number for Jane Seymour! In an exclusive new interview with Closer Weekly, the 68-year-old actress revealed the diet and exercise secrets she follows to keep looking her best as she grows older in the spotlight. “When I have time to do it … I do Pilates and Gyrotonics and I also do a special workout they call The Perfect Workout … which is very, very slow weightlifting,” Jane told Closer at the Open Hearts Gala in Beverly Hills, California on Saturday, February 16.

“[It’s] very, very slow. You only do 20 minutes twice a week,” the Wedding Crashers star explained of her preferred workout. “I notice a huge difference when I do it. Each exercise you do, you do it to fatigue so your whole body starts shaking.”

Though Jane also enjoys practicing Pilates, the actress explained that she doesn’t always have time for that workout because of her busy work schedule. “I do it as often as I can. I have a machine at home but I would say … I’m filming at the moment, but when I’m not filming and I have time, I do it at least twice a week,” she said.

As for her day-to-day diet, Jane explained to Closer that she keeps things pretty simple. “I don’t eat too much starch, I try not to. Mostly I eat … chicken, a lot of vegetables. We grow a lot of vegetables in the garden, organically,” she said. “Everything in moderation, which, of course, is the hardest thing. Me telling myself I’m on a diet never works. Me saying, ‘Okay, I’m going to have a bite of this cake but I don’t need the whole cake,’ that’s how it works.”

As for growing older in the spotlight, Jane said she just tries her best. “I do my best, but I’m not trying to be younger than who I am. I’m just trying to be the best I can be at the age I’m at,” she told Closer. You’re an inspiration, Jane!
