Personal Trainer requirements

Based on the notion of managing workouts and exercises, these are some of the requirements that our Personal Trainer app should fulfill:

• The ability to list all available workouts.
• The ability to create and edit a workout. While creating and editing a workout, it should have:
  • The ability to add workout attributes including name, title, description, and rest duration
  • The ability to add/remove multiple exercises for workouts
  • The ability to order exercises in the workout
  • The ability to save workout data
• The ability to list all available exercises.
• The ability to create and edit an exercise. While creating and editing an exercise, it should have:
  • The ability to add exercise attributes such as name, title, description, and procedure
  • The ability to add pictures for the exercise
  • The ability to add related videos for the exercise
  • The ability to add audio clues for the exercise

All the requirements seem to be self-explanatory, so let's start with the design of the application. As customary, we first need to think about the model that can support these requirements.
