Found a video of an old friend who is still in top shape.

Not bad for a 6'6" 250lb man.
Quite a leaper, too.
He could stand under the basket and with no step/no dribble would launch up and 360 slam-dunk.
(He weighed a little less then.)
MMA abilities are something else.
IIRC, all but 3 of his pro and amatuer fights (total ~18) he finished in the 1st round.
Also adept at real-world brawling.
Worked security with him at a violent nightclub many years ago.
Nobody on Earth I'd rather be next to in a brawl.
His fitness is due to
many years of hard work and a generous bit of God-given talent.
Time and dedication yield results.
