The 31-year-old mother of two, who posed nude in September for Made in Brazil magazine's racy, oceanside spread, said a month later that she didn't gain much weight during her pregnancy, reporte Us magazine.
"This time I didn't really gain a lot of weight. I was actually trying to be as healthy as I could. The first time I gained a lot of weight and it was hard to lose it," Ambrosio said.
The Brazilian-born beauty partially credited breastfeeding and chasing after her tots with her speedy weightloss, though she also revealed that she makes it a point to mix up her exercise routine.
"I love to do Pilates and SoulCycle and go on walks and surf at the beach," she said.
