At the 2013 MTV VMAs, this girl started a kickboxing routine for her single "Roar" under the Brooklyn Bridge. Got an idea for your Saturday sweat sesh? That might not be the prime location for cardio or calisthenics, but the idea was generally exercise. It's Katy Perry's 29th birthday, so get involved in her musical revolution and program this playlist into your iPod.

We wouldn't suggest working out in her music video apparel (a grass skirt over spandex? eh.) but her tunes are the faves of The Mindy Project's Dr. Lahiri, so you get the picture.
