She sure knows how to turn back time! Cher may be 71, but she can still rock a completely sheer bodysuit (like she did at the 2017 Billboard Music Awards back in May). The pop culture icon opened up in a new interview about how she maintains her insanely fit frame — and even revealed her lowest weight ever.

Speaking with People for a profile published on Thursday, Sept. 21, the “Believe” singer said that the secret to her enviable physique is planking on the daily. “I started out with 30 seconds and I thought I was gonna die,” she said of her go-to abdominal exercise. “Now I do three to five minutes!”

Cher, who currently serves as the face of Gap’s fall campaign alongside rapper Future, also told the publication that she preserves her most memorable outfits and ensembles from her career in storage — even if she can no longer fit in them.

“They have to be kept in a unit that is the right temperature so the fabrics are preserved. I don’t plan to re-wear them, but also my whole life I was 106 pounds, and I haven’t been that in a million years! I can’t really get into most of them,” she said before joking, “There’s a big difference between 106 and 126.”

When it comes to her influence on today’s most stylish stars — including Kim Kardashian, Jennifer Lopez, and model Jourdan Dunn, who have been sporting pin-straight “Cher Hair” as of late — the pop diva can see why others might want to copy her signature look. “It’s a good look! I saw Kim do it, and thought it was so great. I’ve worn my hair like that since I was a girl,” the legendary entertainer said. “For now it’s back, but then girls will start doing something else when they get bored.”
