Jessica Alba looks good no matter what she's doing, whether it's strutting down the beach in a bikini or burning off calories on a hike. So, how does she maintain that enviable physique?

The actress dispelled the secret to keeping her lust-worthy figure yesterday in Hollywood, where she celebrated the one-year anniversary of The Honest Company's arrival at Target, a business she found with Christopher Gavigan. “I make smoothies on the run,” Alba told InStyle. “Favorite smoothie right now--I’ve been drinking a lot of matcha green tea with vegan and vanilla protein and banana and almond milk and ice. So, it’s a nice like caffeine jolt and some protein.”

Whatever this beauty is doing to stay healthy, it's certainly working well for her!
