Stand with both feet on top of the band, about hip-width apart.
(Fit Tip: You can control how easy or hard the exercise is by where you stand on the band to create more or less tension.) Start with both arms straight and begin to curl the arms up and towards the chest. Keep your elbows locked at your side. Once you get to the top of your curl, rotate your arms outward and turn your hands so palms are facing away. Press straight up, pause at the top, lower back down and repeat.
