Back in the day Ambrosio would be "off to Pilates class, where I meet a friend and get in some girl time. It's important to break a sweat every day, and I love the way Pilates makes me feel long and lean." “As human beings, we are creatures of habit, We walk a certain way, we take the steps a certain way, we stand a certain way and we sit at our desk a certain way. So our muscles get imbalanced because of overuse and what Pilates does is help to counteract that,” says the Cleveland Clinic’s lead yoga therapist Judi Bar.

2. She’s Done the Tracy Anderson Method

"I am very focused and want to be in tip-top shape for the show, so I try to go [to the Tracy Anderson Method] almost every day of the week. Besides that, I [do] yoga, play volleyball on the beach, and take my kids swimming. I just love being outside," she told PopSugar.

3. She Uses Kettlebells

“In an ACE-sponsored study, researchers from the University of Wisconsin-La Crosse concluded that, in addition to the predicted strength gains, kettlebell training improved core strength and dynamic balance, and increased aerobic capacity. With such a diverse increase in specific exercise markers, it’s no wonder kettlebell training continues to grow in popularity,’ says ACE.

4. This Has Been Her Daily Beauty Routine

“My daily routine is simple but effective. I cleanse my face, occasionally with exfoliator, and I love anti-aging serums that are packed full of vitamin C. BB creams with SPF are great too! How do you take care of your hair? About two or three times a week, after I've shampooed my hair, I apply an ultra-reparative mask from the tips to the lengths and leave it on for ten minutes. Every two months, I go to a salon for a deeply nourishing treatment that leaves my hair feeling fantastic,” she told Vogue France.

5. This is How She Slimmed Down

Back in the Victoria’s Secret days, “About a month before the show I cut out all carbs, and then the week before I stick to just vegetables, salads, fruit and a lot of protein,” she told Vogue. “Cruciferous veggies are loaded with water-soluble and fat-soluble vitamins. Namely, they are packed with vitamin C, A, E, and K. Vitamin C assists in collagen formation, keeping your hair, skin, and nails growing healthily. Fat-soluble vitamins A, E, K work together to support our immune system and promote anti-aging. Eat a variety of these veggies and they will keep you looking and feeling healthy for years to come,” says our sister site Eat This, Not That!
