Casual laughter with those killer abs...nothing like SoulCycle to get your heart pumping and get you working on your summer body (made in winter)! 45 minute spin classes are hosted at 17 studios in NYC and Brooklyn. This total-body workout has you riding to the beat, tapping it back and using arm weights to burn around 400-700 calories per class. Devotees to the "pack" love instructors CharleeString, Akin, Christina P, Sunny, and Joyce
