Everyone knows that the key to having a successful spin class is finding an instructor who plays good music. And with her eclectic mix of alt-rock, hip-hop, and deftly peppered Top 40 hits, Robin Arzon of Peloton cycling studio in N.Y.C. is one of our personal favorite pro athletes-slash-DJs in the game. Because there's really no reason to have your most physically demanding fitness experience be limited to a single 45-minute block, we asked her to curate the ultimate workout playlist for all of your at-home sweatathons (or impromptu dance parties). Listen below, and prepare to kick that resolution's butt.
