If you've seen Fitterati Cassey's workout videos--our new favorite is her Gangnam Style workout--then you know that she can make breaking a sweat look like a blast. So we asked for her songs to help you kick up the energy in your workout. "This is a great gym mix that pumps me up for a run, some weights, or bootcamp class when I teach," the personal trainer says about her girly playlist. Listen to the mix below to get motivated to move!
Tell us: Which songs get you up and going?
