While most girls would kill for a chest like Sofia Vergara‘s, the actress candidly opens up about the pitfalls of having such ample assets in a new interview. Posing in her birthday suit on the cover of Women’s Health‘s “Naked Issue,” the Modern Family star bemoans her large breasts.

“I wish I could be a little more athletic, but when you’re born with these gigantic boobs… I’ve had them since I was 13, and then they got bigger when I was pregnant and had [son Manolo, 24],” she explains. “I don’t know if I’m strong. I have bad knees and very thin bones; I can barely do a pushup.”

Sofia reveals that fitness for her isn’t “about having muscle or cut abs. I don’t have abs because I’m not, ‘I need to be like a fit model with a perfect body.’ That would take too much effort!” Though the brunette bombshell also admits she can’t get away with not working out ever since hubby Joe Manganiello built a nice gym in their house. “It’s like torture for me. I’m in a bad mood two hours before, I’m in a bad mood while I’m doing it, I’m in a bad mood at the end because I have to schedule the next class,” she shares of sessions with her trainer.

Unlike a lot of her Hollywood peers, Sofia isn’t trying to access the fountain of youth. “I’m 45. Even if you want to, at this time in your life, you can’t be perfect. It’s not that you hate it, or that you’re upset about it, but it is our reality,” she tells the mag. “People say, ‘Oh, you look like you’re in your twenties.’ Well, it’s not true. Our skin is different. I had never thought of the word pore, then I’m like, ‘S–t! What do I do with these?'” Well, whatever the Colombian beauty is doing, it’s working!
