Okay, but how to define physical capability? What kind of capability matters most?
I’d like to have better cardio and better muscle endurance in the legs, for example, dancing for hours or walking sight-seeing all day without having to sit down would be awesome.
Yes, the other extreme : be able do everything, even though you probably don’t want to do everything. It takes so much time that you probably won’t have enough time left do the activity you wanted to become fit for.
It takes as much time as you are willing to commit. You asked what is physical capability, not whether you can afford trying to become physically perfect.
