Welcome to Racked's Fitness Week: five days of workout coverage, so that you can start your New Year's resolutions off right.
If you sign up for one of Sweat Fitness' Group Ex classes, Donna Storm may just be the trainer in charge of whipping your butt into shape. The longtime fitness guru — she's been with Sweat since the beginning — leads classes at all eight of Sweat's Philly-area gym locations, and she's known for throwing together a kick-ass workout playlist. If Storm's chiseled abs had a soundtrack, it would include hits by Ke$ha, Rihanna, and five more artists, all of which you'll find after the jump.
