RTR Fitness play online

The purpose of a fitness app is to provide the user with instructions and examples of one or more types of exercise, physical activity, nutritional programs, or some other fitness topic. Many fitness apps are available to play online from the internet. Some are used to count calories, others record statistics on workouts or collect data on walks, runs, and bike rides. Some fitness apps connect the user to a personal trainer or nutritionist to help with areas of concerns when using a specific fitness routine or just generally with workouts. Further, some fitness apps provide a coordinated series of songs, each having the same beat when doing such workouts as running and fitness classes.
