At their core, there’s a philosophy that drives all Apple Music Fitness Mixes: “Music is this primal tool that gives us that extra boost of energy during our workouts,” Valentino Khan tells Apple Music. “It’s a pretty crazy idea, but it’s so obvious. For most people, it’s almost a requirement to any fitness regimen.” As such, the LA-based DJ/producer assembled the first-ever Fitness Mix for the gym, a nearly hour-long set to guide you through weight training, a HIIT workout, or any other equally challenging fitness routine. “I wanted to keep the energy high, while still selecting tracks that were pleasant to listen to—to play in any setting. It’s a bit of a crescendo, with the higher-energy tracks towards the later stages of the mix. At the same time, I wanted to give people a great ending that they can ride out to.” Amid this mix of house and hip-hop, a couple of key tracks Khan included are his own “Your Body,” with Nitti Gritti, and “a crazy flip of Drake, ‘Nonstop,’” he says. "It feels like a great cooldown song that builds back up into another round of intensity.”
