“Do you feel as good as you look?” Oprah Winfrey asked a svelte and sexy Jane Fonda during her appearance on The Oprah Winfrey Show last week. “Yes,” the 72 year-old Fonda said. “I think it’s just getting better!” Almost 30 years after she helped spread the aerobics craze around the country, Fonda is slipping back into spandex for “Jane Fonda: Prime Time Walkout” and “Jane Fonda: Prime Time Fit & Strong,” two new DVDs set to hit stores on November 30th. “It’s not marathon stuff,” Fonda told Oprah of the low-impact moves, meant to motivate people of all ages, including seniors, who are looking to ease back into exercise. “It’s very doable.” While Fonda (who became a bona fide sex symbol when she starred as a space-swimsuit-clad astronaut in the 1968 flick Barbarella) admitted that she’s also used cosmetic surgery to stay looking great, she maintains that staying in shape is the best way to fight the effects of aging. “I’ve been writing a book…and in the research I did, it was clear that one of the most important things is to stay physically active,” she told Oprah. “Not just for your body and your muscles, but for your brain.” She may have lost the leg warmers, but Fonda’s still got the ability to inspire!
