Workout Builder should be pretty simple to use. If you are in it, you can simply do a search for the exercise(s) you want. Once you have found an exercise, you can either drag it from the full screen of exercises to the right hand side (to create a new workout). Or, if you click and open the specific exercise, you can simply hit “add exercise”. It also allows you to edit the specific exercise as you wish for sets, reps, weight, time, and/or notes and comments. My clients really enjoy this option.
Once you have selected all of your exercises and made specific notes, there is an option to e-mail your client and/or print the new workout.
Hope this helps, but if you need more assistance you may want to call IDEA directly.
