Resham Kamde works hard at looking good. The 22-year-old event manager spends half a day every fortnight at an upscale beauty clinic in Bandra, Mumbai, getting ‘the works’ — manicure, pedicure, facial and hot oil treatment for her hair; every month, she gets a trim and her honey-blonde highlights touched up. She used to run for 40 minutes every day on the treadmill at the gym in her building, but Kamde has recently discovered Zumba. She has signed up for classes at a dance-fitness studio nearby where, twice a week, she burns up 1,000 calories in a session of the Latino routine that combines dance movements like salsa, merengue and aerobics. She has raved about it so often that her boyfriend and a couple of friends have also joined her class.
