The mother of two somehow manages to look insanely fit, despite a busy schedule balancing family and work life. But thankfully for us, the star opened up about her tips and tricks to keeping in shape.
And just like most gals, Alba needs to keep things interesting in order to keep up with her fitness regime.
"I like dancing," she admits. "There's a choreographer I used on a couple of movies, JJ Dancer [aka Jennifer Johnson]; her dance moves are so fun, so it doesn't feel like you're working out. And I like interval training on a treadmill, with sprinting and then uphill walking, then sprint, then uphill walk, then sprint. This morning I did sprint intervals with a high-incline walk. Otherwise I get bored—I can't just do the same thing over and over."
And while her fitness plan is obviously working, she still laments not having appreciated her body in her younger years.
"I was a lot more critical of my body when it was probably pretty awesome," she revealed. "It's like, why did I not ever wear jean shorts? That's so crazy. I was so skinny! I didn't have any cellulite...what was I thinking?!"
Luckily, it looks like Alba still has plenty of time to rock leg-baring looks, and she's decided to flaunt what she's got.
"I was more willing to wear short skirts after I had my kids," Alba said. "I never wore them before. Ever. I was so self-conscious. But I remember I was 28 or 29, at an MTV award thing, and my girlfriend Kelly was like, 'You should wear a short skirt, because you are not going to be this age forever.' Now I'm a lot more confident in my skin—because who cares? At the end of the day, it's so much time spent on something that really doesn't matter that much."
