Warming up is a crucial part of exercise. How about giving people a fun way of doing it? The Qitele Royal Arm Rotation Station lets people warm up their arms. Up to two people can use the Royal Arm Rotation Station at a time. Exercising is always more fun in groups. Like all things Qitele, it is made from highest quality materials including galvanized steel. The galvanized steel frame is powder-coated to ensure the Royal Arm Rotation Station is able to stand rough weather conditions and the most intense use. Each of the arm rotators works independently in a circular motion. With a compact structure, it is definitely a space saver. It is perfect equipment for the parks or gym classes. It works either way.
