Brooke Shields has forced herself to get a personal trainer.
The 52-year-old actress insists she has "never been skinny", and when she was younger her athletic build was not "celebrated", but the star has had to get an expert as part of a "very sort of rigorous rehabilitation programme" to help her avoid having surgery on her back, which is an injury she suffered dancing in Broadway shows.
Speaking to PEOPLE, she said: "Since I've turned 50, there's been more focus on my body than ever.
"I have never been skinny. The thing is, I was in an industry where [being athletic] was not celebrated. I have friends who are supermodels, and I never had that body. I've never been asked to walk in a Versace show.
"I have a trainer, and I'm not a trainer person. But I've had to enter into a very sort of rigorous rehabilitation program to avoid surgery on my back. I've already had four surgeries on my feet and two on my knee - all from Broadway dancing injuries. On Broadway, they don't really rehab the dancers like they do in sports. It's, 'The show must go on.' Maybe you'll get five minutes with a physical therapist, or they'll get someone to come in and tape you with kinesiology tape, which is what I sort of lived on for a long time."
Although Brooke - who has Rowan, 14, and Grier, 11, - has a personal trainer, she doesn't like the "one-on-one scrutiny" of the fitness fanatic putting her through her paces.
She said: "I don't like the attention. I don't like the one-on-one scrutiny."
However, the 'Endless Love' star has insisted there are "zero frills" with her fitness regime, as she will attend SoulCycle classes and Pilates.
She explained: "The trainer is zero frills. And I have to mix it up. I started SoulCycle about 12 years ago, and I was there this morning at 7 o'clock. I've started Pilates, both a class and with a private teacher. But all of that, it's expensive. I find the psychology interesting: It's easier for me to justify doing something like going to the gym and making it a priority because it's from an injury. If it was just because I liked it, which I do, it feels like a luxury to me. And I feel guilty about that luxury. There's a stigma about how working out is somehow for people who don't have a job, or it's an indulgence."
