One of the reasons that we bought the Zenogym instead of other exercise products was that we didn't want the cost of a monthly subscription. Well, guess what boys and girls? There is absolutely NO documentation to help you figure out how to do ANY exercises. If you install the app on your phone, they do have some 6-10 SECOND videos talking about the exercises, but in many cases you either don't get any info on hooking the cables to the unit, or they tell you how to hook the cables and may give you a sec or two of the actual video. I'm guessing the only way to get the full info on hooking cables and the exercises is if you pay the monthly subscription.
For us it will be a trial and error to figure out the hookups and the exercises. Once we figure that out, we will either use a spreadsheet or a word type document to keep that info easily at hand. Spending the type of money that they want for the unit, there should be documentation for the exercises.
