I am sure he can "run" a mile. Anyone can. Even the most out of shape fatbody can clock in around 10-20 minutes.
Running or doing some kind of cardio workout is much better than being a fat lethargic permabulker(CSWOL), with your posts it would look that you advice people NOT to improve their cardiovascular state.
But I agree too much of ANYTHING is bad for you.. like 8hrs arm workout a la R(BI)ich Piana.
Most runners also seem well spoken, sound mind & very humble, while bodybuilders are insecure, clinical insane & not very intelligent. /JK there's good and bad in everything, just learn to take the good and avoid the bad.
