Aubrey O'Day #96 -- Celebuzz's 101 Hot Bodies
Working out is key to having the endurance and stamina Aubrey O'Day needs on stage. "It is important for me to work out with a trainer because they push you past your own limits. They show you that you are more than you think you're capable of," the singer says on her Oxygen.com blog. The 28 year old star follows a vegan diet and stays slim by running, spinning and swimming. "I love swimming. Sometimes I make up dances in the water; it’s so fun," O'Day blogged. "My least favorite workout is running on a treadmill, anything repetitive!"
