Each month, the Apple Music Fitness Mix is helmed by one of dance and electronic music’s best DJs to deliver the perfect set for your next workout. This month’s edition, assembled by Boulder, Colorado, DJ/producer Disco Lines, is full of upbeat selections for your next gym session. “Music is a huge part of my workout regimen,” he tells Apple Music. “If I forget my AirPods at home, I’m not working out.” The producer, whose real name is Thadeus Labuszewski, describes himself as a loyal gymgoer and practicing yogi, and wanted to capture a balance of harder, heart-pumping tracks alongside songs to get you in your flow state. Among his favorites: J. Worra’s remix of Disclosure’s “When a Fire Starts to Burn” (Labuszewski says it “gives him energy” when he’s losing steam) and “Between Us” by Icarus (“This is what I listen to when I’m getting ready to go surfing or skiing,” he says). His pitch is simple: “Put this mix on, lock in, and get swole.”
