Abstract: An application software that combines instructional cues with music along with a graphic representation of a workout, such as a cycling workout, for teaching one or more individuals riding stationary bikes, or regular bicycles on stationary trainers, performing other exercises, used for indoor exercise or training. Instructors of indoor cycling or Spinning® classes can use their mobile device to create a class that contains music for the class, their instructional cues by voice or text, and an automatically generated graphic profile of the ride of workout. The climb or graph is represented by harder exercise efforts appearing higher on the graph, with easier efforts appearing lower as a function of the target heart zone or percent of max heart rate. Colors can be associated with specific cardiovascular or power zones of physical difficulty or intensity.
