Janet Jackson has been a mainstay in workout soundtracks since “Control” first swept up dance and fitness clubs in 1986. “Her songs are about reclaiming your power,” says Apple Fitness+ cycling trainer Tyrell Désean. “They’ve taught us to love ourselves, fight of our worth, and do it in our own style. She is a true trailblazer, period.” From the military precision of “Rhythm Nation” to the sweaty euphoria of “All for You,” these tracks showcase why Janet—the architect of modern R&B-pop who inspired everyone from Britney to Beyoncé—remains the ultimate workout companion for those who want their workout extra fierce.
