Emma Stone has revealed she gets a "deep-seated rage" when working out in gyms.

The Help star opened up to S Magazine about her love of food and not going overboard with her exercise regime.

In fact, Emma says that she positively hates lifting weights because it brings out the worst in her.

"Running is bad for your knees and I like to do things I actually enjoy, like going for a swim," she explained.

"I had a trainer during Spider-Man and I discovered I have a deep-seated rage when I'm holding heavy weights over my head.

"Whatever dormant anger I have in me, that's where it comes out. That's not the kind of working out I want to do.

"I would much rather sleep at night than want to throw a weight across a room at someone. I'm usually a pretty peaceful person, but for some reason when I get in the gym something bubbles up in me.

"I haven't worked out in a month and I'm proud of it!"

The 23-year-old actress also claims that she is not totally happy with her physique.

"I do have that thing of, Oh my God, I'm disgusting! I ate a huge Wagamama lunch, the whole yaki soba, and I feel so fat," she said. "But I'm still gonna eat that stuff, and you know what? You can get nice, loose clothes that cover it all up."

Emma is currently dating her Amazing Spider-Man co-star Andrew Garfield and says she still goes to great lengths to keep herself concealed.

"I'm not gonna go parading around in a bikini, OK, I did that in a photo shoot once, but it's about what you're comfortable with at the time you're comfortable with it. That was a good day, but you won't hear me saying I have no body issues because I wouldn't be human if I didn't."
