How does an Upper Body Ergometer (UBE) typically function?

The Upper Body Ergometer (UBE) is designed to provide a cardiovascular workout that primarily targets the upper body, particularly the arms and shoulders. It resembles the function of a stationary bicycle but is specifically adapted for arm movement instead of pedaling with the legs. Users grasp handles connected to a flywheel and move them in a circular motion, similar to cycling, thereby engaging the muscles of the arms, shoulders, and sometimes the core, while improving cardiovascular fitness.

This mechanism allows for a low-impact workout, making it suitable for rehabilitation, fitness training, and conditioning for individuals who may have lower body limitations or who want to focus on upper body strength and endurance. The UBE is commonly used in physical therapy settings as well as in fitness facilities.

Other options, such as using foot pedals, rowing motions, or weightlifting actions, do not appropriately describe the primary operation of an Upper Body Ergometer, thus confirming the correct functionality is through a cycling motion for the arms.
