Defining the F-word

What does it mean to "be fit"? This is a question that has plagued me for a very long time. However I seem to define it, I can always produce numerous counterexamples to convince myself that my original definition was not inclusive enough...or maybe was too inclusive. To that end I am putting the question out there (or as you can see below, many questions) about fitness and what makes an individual fit. 

• Who is fit?
• Are all/most athletes considered fit?
• What makes an athlete?
• Is there a body-fat percentage cut-off to being fit?
• Can you run a marathon and not be fit?
• Can you deadlift/squat 300 lbs and not be fit?
• Can you be fit and overweight?
• Can you have a crappy diet and be fit?
• What about a really crappy diet?
• Can an overweight smoker with a really crappy diet be fit?

Ok, maybe I think I know the answer to that last one...but I have thought about these questions a lot over the past decade or so and my answers seem to change over the years so I will first share my current answer. This answer has come about through many arguments discussions with Ryan, my siblings, and various people I've interacted with recently. Per my usual method I made a diagram/chart that helps me define what I see as "fit". Please note that if someone does not fit into this somewhat arbitrary definition, it doesn't mean I don't see them as fit or wouldn't if I ran across them somewhere. What this chart does tell me is that an individual that meets the criteria would likely be seen (by me) as a fit individual. With that...here it is!

Directions: Choose 2 (or more) from the 1st column, 1 (or more) from the 2nd column, then follow the chart for 3rd and 4th columns.

What do you think? How do you define fitness?
