Today, fitness is defined as the state of ''being fit'' as to whatever that means! lol  I don't think I fit that category! lol
I enjoy exercise, but I need to do more research about physical fitness. It is a state of well-being, health and the ability to perform sports, occupations and activities. Indeed. I used to run in college, but then I started having trouble with my knees. What else might I try? Well, what I can tell you is that Physical fitness can be achieved through proper nutrition, physical exercise and rest. So, it's a combination of those things and not just exercise Also, before the industrial revolution, the capacity to perform daily activities without undue fatigue was the definition of fitness. I guess so. Life was harder back then, especially if you spent all day working in the fields.
