It comes as shocking news that one of Detroit’s always-energetic, engaging fitness cheerleader is quiet. Julie Hecker, the leader of the Motor City Rah-Rahs and Punk Fitness died of a massive heart attack on Wednesday.

From the Freep:

Hecker, 44, was a vivacious personality who bridged her own love of dance and exercise with the city’s gritty rock scene. It was an unorthodox combination that often found her with hula hoops and bright sportswear leading crowds of leather-clad rockers through energetic dance routines.

“Anyone who has that energy is like a pied piper,” said Vinnie Dombroski of the bands Sponge and the Orbitsuns. “She had that spark, and people wanted to see what the spark was about. She knitted the whole scene together. That’s why so many people are shocked and just sick over this.”

The Metro Times also has a touching blog entry, Remembering Julie Hecker.

I worked with Julie only briefly while doing sound for the Detroit Derby Girls, where she was a fixture. She really worked the crowd during halftime and introduced a helluva lot of Detroit kids to hullahoops!

She also proudly promoted Detroit music during all of her routines, something I really appreciated.
