Peloton Instructor Robin Arzón’s Must Haves — Including a $3 Protein Shake

On busy days, Arzón keeps things easy without sacrificing fuel. "The Oats Overnight Party Variety Pack ($31, originally $39) is my go-to when I need something quick and effective," she says, noting each is packed with protein and carbs and is easy to grab on the go. Whether it's fueling a workout or a packed schedule, it gets the job done. You can grab the Oats Overnight shakes individually, too. Our favorite? The Oats Overnight Maple Brown Sugar Protein Shake ($3).
