The "American Idol" judge graces the cover of the March issue of Glamour UK, where she's talking about how she maintains her amazing body.
"I've got an athletic body, I've worked out my whole life and I've been incredibly disciplined when I needed to be," she told the mag. "Now I'm just a little bit more relaxed in that area. I feel like this is who I am. But it's also hard to shed that old skin."
So, how does J.Lo find a balance between enjoying herself and spending countless hours in the gym?
"Mentally, I'm always thinking about it," the mother of two explained. "I'm OK looking this way, but at the same time that ambitious, determined girl inside me is like, 'Come on, let's be in the best shape ever and really show everybody.' Then the other side of me thinks, 'Let's just relax on the beach chair.'"
She added, "I'm not one to overindulge. It doesn't make me feel good. Some people find it comforting to sit down and eat a whole pint of Häagen-Dazs, but honestly that would make me throw up. I don't think I've ever eaten that much."
The 44-year-old certainly knows what's good for her body!
Lopez also opened up about her relationship with Casper Smart.
"The dream is to have a balance where you feel you could relinquish control from time to time and still be taken care of. It's about finding a relationship that has enough good stuff to outweigh the bad, because nobody's perfect, right?"
