Apologies, I did not mean the English expression of fit, rather the status of sports fitness levels, he's doing ok for his age.

I don't think that term applies either. He appears to be quite overweight.

In the military I saw people get kicked out for being “overweight.” Interestingly, they could run circles around you for 12 miles, throw you several yards, or otherwise destroy a Physical Fitness Test.

Looking “overweight” can be quite deceiving.
