This seems like an individualized answer but here goes
If you are more sedentary I would say you would want to find ways that get you to walk around,stretch and take breaks just to move your body. Find something that makes the blood flow and circulate.
if you are the average person you may be adding activities when you can but it is not a commitment. therefore it would be the goal to set a more scheduled system of activity.
this person has the recommended activity level they know their body and preference they are able to maintain their body with the amount of activity they do.
this person is in the gym almost 24/7 they take care of their body but due to the amount of activity they have a limited range of motion and flexibility (body builders ect)
