What does it mean to be sedentary?

Answer 1

Usually this means not physically active. For example, a doctor may ask you to describe your fitness level or how much exercise you get at work. If you work at a desk typing in number, go home and watch television and the only lifting you do is a remote control, you are sedentary. If you have that same job but go to the gym for two twenty minute workout sessions and enjoy walking in the mall, you're somewhat active. If you work at a loading dock, enjoy practicing kung-fu three nights a week and do a lot of kayaking, you are very active. My father likes to say he suffers from "Sedentary Lethargitis", a fictionally named condition which redundantly means sitting there and being lazy.
