Stevie Nicks is 60 but she still feels like she's on the "edge of 17," thanks to super-efficient Power Plate workouts that have whipped her into incredible shape.
"When I gained my 30 lbs., it was because I went on tranquilizers for eight years," Nicks told PEOPLE Monday, the day before her new CD, The Soundstage Sessions, and Live in Chicago DVD hit stores. "I don't blame myself for that."
The secret to staying slim is finding a healthy weight you can maintain, says the "Rhiannon" chanteuse, who is now a sleek size 8 and is touring with Fleetwood Mac for the first time in five years. "You don't have to weigh 105 lbs. Weigh 125 lbs. and stay there."
The singer adds that had she not been on tranquilizers in the '80s, "I would have stayed at 125 pounds from 1985 and [later on] probably would have weighed about 130 pounds. That would have been way better than fighting to get back to 130 lbs. from 175 lbs."
Short, efficient workouts on the Power Plate every other day have helped her keep the weight off. "I do it every other day for 13 minutes," says Nicks of the Power Plate, a machine with a vibrating platform that revs up workouts by forcing users to contract and release their muscles up to 50 times per second to maintain balance. "You can't get results faster than that."
Her other secret to looking so young? "I take good care of my skin," she says. "I never go to bed in makeup. I haven't laid out in the sun since I was 28. While everyone else is out there burning up, I'm walking around going, 'When I do look 60, you will all look 100. Enjoy it now because you aren't going to be happy when I look young enough to get a date and you don't.' I'll still be going out when I'm 75. Everybody else will be in the rest home!"
