There is no vaccination yet for the "Pandemic Blues," but a temporary cure was shaking out in vivid colors in a second-floor exercise studio at Life Time Canton last week. Led by master Zumba instructor and Canton resident Shyam Thakker — and fueled by rhythmic Bollywood-themed music and colorful, flashing lights — close to 25 people sweated out their worries Jan. 27, just a few days after group exercise workouts were allowed to continue after the lifting of a three-month ban by the Michigan Health and Human Services Department. Thakker, the owner of Desiboy Fitness, offered free outdoor group workouts in metro Detroit parking lots during the summer when the spread of the coronavirus led state health officials to pull the plug on indoor group workouts to help contain the spread of COVID-19.
