Shouldn’t I be doing more sets or weight?

The app has been programmed with an expert-system AI that makes very, very good estimates of how many sets and how much weight you need to get your best results, so it is generally a good idea to trust in the recommendations. As you give the app feedback every workout, its recommendations get even better and more precise to your body’s specific needs and responses. There is a wide range of reps that lead to hypertrophy and a great sign that you are doing the work needed, is remaining close to your RIR that is assigned for the set. That being said, if you want to add sets or change the weight the app recommends, you can always do so.
