Set-up: Stand next to an immovable object with resistance band fixed or looped securely around it at shoulder height.
Movement: Grasp the band with the hand on the same side as the supporting object so that the arm is straight out to the side and parallel to the floor. From a strong, stable base move the band towards your hip. Hold briefly at the bottom and return. Do not use momentum, and maintain control both lifting and lowering the band.
