What's the secret to Audrina Patridge's killer cut bikini bod?
A Hula-Hoop, apparently! We caught the former Hills star posing on a balmy beach in Los Angeles yesterday. The toned reality star wore an athletic (yet equally sexy) blue two-piece for her latest photo shoot for a new workout regimen.
And what kind of body-chiseling workout, you ask?
Audrina reportedly lifts a weighted Hula-Hoop to tone her arms and then spins the ring around her waist to target her rock-solid abs.
While we may not all achieve her made-for-(reality)-TV bod, investing in a plastic hoop is definitely worth a shot!
