This movement looks quite simple but is sure to make your shoulders burn. Stand with arms stretched wide, parallel to the ground, with wrists aligned with shoulders. Make small circles (think grapefruit-sized) in either direction. Maintain one direction throughout the interval, or switch half way through.
