Weak point training

Hi there Carl,

I was wondering if in the future there would be a way for the app to engineer weak point training. As a competitive bodybuiler, albeit a physique athlete, one is always trying to work on balance and symmetry. I just thought that this could be an awesome inclusion into the app (if possible of course) if it could come from a scientific background. 

I am not sure how you would "teach" the app how to gauge the user's weak points but maybe this could be done via user-based feedback. So for example if I were able to tell the app which parts of my body I feel are lagging behind then it could readjust my programming to try and overcome those weak points.

Obviously I could program that in myself, but it would be amazing if this could be done in a scientific way by the app (utilising excercises shown to affect growth in said weak areas). 

Kind Regards,

Stacy
