St. Clair Shores resident Nancy Krzezewski sipped a frosty beer before her recent Saturday workout. To a Punk Fitness Detroit regular, there's nothing strange about that. Or about what followed -- an afternoon workout that included hula-hooping on the rooftop patio of the Magic Stick on Woodward in Detroit, set to a soundtrack from artists like the Dirtbombs and the B-52s. This is the brainchild of Royal Oak's Julie Hecker, a self-professed Detroit cheerleader who started the classes six years ago to appeal to the creative class of artists and musicians. Her concept: promote fitness through workouts in unique settings while introducing like-minded people to one another, new music and interesting upcoming events. Detroit Free Press
