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."
