As I mentioned before, walk up a flight of stairs, have some strength, some degree of flexibility, certainly some mobility, maybe even dynamic mobility, et cetera. And in order to address those or improve upon those, they could look in those covers and say, well, how much running, swimming, long form cardiovascular exercise am I doing per week? How many steps am I taking per day? How many times a week do I lift objects that are slightly heavier than is comfortable for me to lift, et cetera?
