Would you be interested in a congolese dance workout? I'm going to a workshop at 1pm on Saturdays that I really like. $10 to drop in, really good aerobic workout. Health and elegance dance studio on Fountain Square, on Washtenaw.
The instructor, Bisi, is here from the congo working with a local congolese dance troupe. Right now he's having the dance troupe join the class to keep the energy up, and that also helps in figuring out and following the moves, since sometimes we turn around.
I just took zumba for the first time at ypsi studio this week, and I'd say they're comparable in difficulty, but the congolese dance is a bit more of a workout.
