Before she was the movie star, pop star, and otherwise indomitable cultural force that she's become, Jennifer Lopez started out dancing as a Fly Girl on the sketch comedy TV show In Living Color—in other words, keeping fit is in her DNA. Since then, she's taken her natural sense of rhythm and gift for choreography and blended it with pop, R&B, and hip-hop to create some of the biggest high-energy dance-floor anthems of the last few decades. This selection of her best workout tracks, chosen by Apple Music editors and Apple Fitness+ trainers, is designed to get your heart rate up and keep your body moving. "I love the way she lives out loud, with so much pride for her Latin roots," says Fitness+ Strength trainer Sam Sanchez. "It showed me as a young girl to be proud of where I come from and the things that make me different. She is why representation matters to me."
