Hot beach body alert!

Audrina Patridge stripped down to her summer workout gear for a quick training session on the beach and RadarOnline.com has the photos of her in a tiny bikini exercising with a hula hoop.

The California cutie grabbed the hoop and hit up a Los Angeles beach on Tuesday where she showed off her banging bikini body while she burned some calories too.

The Hills star revealed her picture perfect frame as she stretched and ran on the sandy shore.

The 27-year-old has a bombshell body that she keeps in shape by using a weighted hula hoop for her workouts, toning her arm muscles as she lifts it and getting a core workout as she spun it around her waist.
