An exercise is the smallest unit that you can add to your application. It should be concise, precise, and include all the necessary steps to perform it correctly. Examples of an exercise could be a pull up, push up, utkatasana (yoga chair position). 

You will be required to upload a video showing how to perform the exercise. It's recommended for this video to be short and precise, and not longer that 30 seconds. 

In addition to the video, you can explain in detail and give indications using the description field. Try to break down your exercise in smaller steps, and explain each in a simple but precise way.

Users will be able to see your exercises individually, and also you will be able to use them to form workouts.
