This is really awesome! I used to have an movement to tissue mapping in an earlier version of app but I opted to focus more on the weight-reps curve it because the tissue volume calculations added too much complexity to the interface, and it just encouraged me to do too many different movements. So exercise selection and tissue coverage is something I actually think about outside my app. I had coefficients mapping each exercise to its tissue impact but it was kind of arbitrary and unscientific - even between athletes you will have different techniques on the same movement that will impact tissues differently. I do think that workout design is a super important area and I hope you crack it, it was too hard for me to do a good job on.
