When you are working on building out your Programs, use the Copy Exercise button to make it easier to add variations of the same Exercises. This is available by selecting a Library Exercise from the list. Once you have saved an Exercise, it is added to your library. When an Exercise is in your library you can then use the icon found below, to Copy Exercises. All you have to do is give it a title and you will be brought to the copied form of the Exercise to modify and save.
