Audrina Patridge shows off her new workout - and its results - on a Los Angeles, California, beach on Tuesday

Forget the gym, all you need is a hula hoop to get a great bikini body like Audrina Patridge.
The former Hills star left traditional workout devices at home, embracing the large hoop as a way to tone and show off her amazing figure on a Los Angeles, California, beach on Tuesday.
But while a hula hoop is known as being a toy loved by children across the world, what the reality star was up to was hardly child's play.

Forget the gym: Audrina Patridge shows off her new workout - and its results - on a Los Angeles, California, beach on Tuesday

Unlike most hula hoops, the 27-year-old's was heavily weighted to ensure maximum toning as she used it both the traditional way - spinning it around her waist - and like a resistance weight, by lifting it up and down to get her arm muscles flexing.
And, Audrina's new workout is obviously working, as the star did not have an ounce of fat or cellulite visible as she frolicked around the beach.
Wearing her brown hair out and flowing, the star simultaneously flashed her bright white smile and perfect abs as she toned and tanned.

Perfect front and back: While many may opt for workout gear while they exercise, the 27-year-old preferred to wear a tiny string black and white bikini which highlighted her toned legs and rear end

Making sure to get the most out of the sunny almost-spring day, the reality star wore a barely there bikini.
While many may opt for workout gear while they exercise, Audrina preferred to wear a tiny string black and white bikini which highlighted her toned legs and rear end.
Giving her swimwear a more stylish edge, the Maximum cover girl added a contrasting black bikini top that featured a multi-strapped design at the back.

Versatile workout: The star used the hoop to do yoga like stretches, tone her waist by using it the traditional way and build muscle in her arms by lifting it up and down

While having so many straps is never good for the tan lines, the brunette bikini model did not have to worry too much as she just returned from a sunny quick trip to Spring Break and already looked very tanned.
Audrina was the guest of honour at the Curve fragrances and Maxim's party in Panama City, Florida, last week.
The actress even got a chance to show off her new skills as besides judging a booty shaking contest there was also a hula hoop competition.
