There's no rest for the weary. Jessica Alba [1] just showed us all that a family vacation [2] is no excuse to stop your fitness routine as she hit the water for some core-strengthening paddle-boarding in Maui, HI.

The actress and entrepreneur, who credits martial arts and a strict routine of yoga and Spinning [3] for her strong body, demonstrated her balance skills on the water in a skimpy Shoshanna bikini [4], making the whole workout seem like a piece of cake — if you've ever attempted to stand on a surfboard, you know it's no easy feat at all.

From the look of these photos, it's clear Jessica's commitment to fitness and health [5] is something she works on every day — in between gorgeous red carpet appearances [6] and flawless street style moments [7], of course. Read on for more photos of Jessica's impressive physique and get ready to feel inspired to hit the water at your next tropical getaway.
