I'd like the main focus of the app to continue to be the daily routine as I think it's a nice nudge to a create a simple habit with great health benefits.
Having said that, I have a couple of routines lined up that target specific body parts for those days when you want to really go for the stiffest areas (ETA: these would just live permanently in the page).
I wish we were more okay as a society with some good things staying good and simple.
