While most people consider healthy competition to be all about focusing on doing one's best and having fun, Fergie has a different take. The singer hits the gym with hubby Josh Duhamel and competes with him to get healthy. "Working out with Josh inspires me, but he is competitive. And loud!" Fergie tells Self magazine. "Men scream and go crazy in the gym. I'm a silent workout partner, but when my adrenaline gets up, I talk trash. I'll wait, and when Josh does something embarrassing, I'll throw a jab!" A little lighthearted competition keeps Fergie -- who posted this Twitpic of herself on vacation in Cancun on May 28 -- in the gym up to six times a week doing a combination of cardio and ab sculpting moves with trainer. Take a page from Fergie's workout manual, and bring your beau to the gym to see who can do 60 minutes on the elliptical or who can do the most crunches. Get Fergie's go-to exercise moves on Self.com.
