1. She’s Organized

Ambrosio shared some of her wellness secrets and her daily routine to SELF. One of her morning secrets is staying organized, which helps with her busy schedule. "I love what I do, and if I'm organized, there's time for it all," she says. "I usually pick outfits at the last minute, and my beauty regimen takes less than 30 minutes. I glance in the mirror to make sure everything is in the right place!" She also says that this organization allows her to both make breakfast and do a quick workout in the mornings.

When it comes to working out, Ambrosio does a lot of different things. One way she likes to workout is straight out of the film Rocky. Yes, she likes to run up the stairs. Ambrosio tells SELF that she likes to do this to workout her lower body, and help with her cellulite. “I run the Santa Monica Stairs. They're really hard. I'll go up and down the [170] steps four to six times, usually once a week. It definitely helps the butt and legs while you're getting a little sun and fresh air at the same time."

3. She Works Out Her Lower Body

Stair climbs aren’t the only way Ambrosio likes to workout her lower body. She tells SELF that she really prioritizes her lower body workouts, and does a lot of different exercises to keep them in shape. “In Brazil, it's all about the butt. Some girls naturally have the big round one, and they aren't shy about it—that makes them sexier. Others work out to have it. For mine, I put 5-pound ankle weights on each leg, get on all fours and kick each heel up toward the ceiling. I do three sets of 20. Then I also do three sets of 20 fire hydrants, where you lift each bent leg up and out to the side."

4. She Enjoys Life

Ambrosio tells SELF that one of her wellness secrets is enjoying her life. She says that she likes to live like she’s on vacation all the time. "'Forever on vacation' is my motto. It's just the way I take life. Nothing makes me feel that pissed off or out of control. Whatever I do, whether I'm modeling or doing my clothing line, ále by Alessandra, I just want to feel like it's fun. If you're doing something you don't like, you're wasting time. Life is short. There is so much to see and do and feel. We should enjoy every moment."

5. She Loves Dance-Based Workout Classes

Ambrosio is a fan of fun, dance-based, workout classes, and she has one particular favorite. “I’ve been doing a lot of Tracy Anderson now, and it’s a lot of dancing cardio, and I love it,” she tells E! News. "The music is really loud and you don't feel like you're working out; you feel like you're dancing, and learning all these cool dance moves. I might just put a DVD in my room and look like a crazy woman.”

6. She Does A Lot Of Cardio

Ambrosio tells Harper’s Bazaar that she does a lot of cardio workouts, especially when she’s prepping for a fashion show. She admits that while she’s not always a big fan of some cardio workouts, she still does them as a way to stay in shape. “I have never been a fan of running, but lately I’ve been doing it and also have figured out different ways to incorporate cardio in my everyday routine. Instead of running indoors I go for a run in my neighborhood, take a hike with friends or play volleyball at the beach.”
