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 participate of 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?

I was a tennis player but that is bad on the knees. Physical fitness is generally thought of as proper nutrition, exercise and an adequate rest period.

So it's a combination of those things and not just exercise?

Yes! Before the industrial revolution, people thought of fitness as the ability to get through the day's activities and survive! lol

I guess so. Life was harder back then, especially if you spent all day working in the fields.

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

Ha! Well, all we can do is try. But it can't help us too much if it just leads to more anxiety.
