She's been doing Lagree Fitness for almost a decade. The workout is "a low-impact, high-intensity method that tightens and tones in as little as 20-minutes a session." "I really love the workouts since then, because I have bad knees. I can't do crazy things. And this is one of the workouts that I feel that I can finish and do most of the things without even thinking about my knees. For me, that's what hooked me to  this workout," she has said. "Because in one hour you feel like you do everything good. Like you feel like you completed one workout, then I'm done for the day. I don't have to think anymore about exercise. And actually, growing up in Latin America, there was not that culture. Right. You know, 30 something years ago." She added: "It's not a pleasure to work out. So I do it because also because of my job and I'm in a place in my career where I need to have energy and look good and fitting into those tiny little dresses."

As for Lagree: "It's great because… you don't get bored because there's so many exercises and… time flies. And I'm very glad that I found this because it's one of the few things that I can finish. I always explain it as the 'necessary torture.' Like, you know, like at the beginning they will tell me an exercise. I'm like, no, I can't do this. And I would be like, no, it's horrible. It's horrible. Now. I'm like, I, I get it. I can do it."

On Ellen, she host showed photos of Vergara eating with her mouth open very wide. "Well, first of all, I didn't know I was doing that. I didn't know I had a problem until people started posting pictures of me, from paparazzi, of me eating. And then I started to realize it's like, what is wrong with me? Well, but you know, you have to give it to me that I'm always long hours on a set. You get bored, you get, you know, a little anxious and what else are you going to do? right. But I have a technique that my makeup artist appreciates because you open the mouth really wide and you don't mess up your lipstick."df44d9eab23ea271ddde7545ae2c09ec

"I try to have a routine, but sometimes it's hard because of the kind of job that I have," she has said. "For example, I woke up today at three in the morning. So today's not gonna be a workout day for me, no matter what, I know that I'm not gonna have the energy at the end of the day. So I try to work out according to my schedule, my shooting schedule. If I'm traveling, I usually don't work out. But I try to squeeze in at least three times a week working out. I try to sleep well. And because, I mean, I think it's important when you do that kind of job that I do to sleep well."

"I have never been into crazy diets. So I usually try to eat healthy of course, because I love vegetables and I love healthy food and juices, so I'm pretty good with that. My problem always has been my obsession with sweets and that's why I'm here today because it's one of my biggest secrets is that I've always been trying to figure out a way to get away with trying to eat something sweet after a meal," she said about Skinny Cow.
