I think i saw this on tv in the 90’s the guy who at first i thought was Chevy chase became able to do physically exhausting exercises without ever being winded i think they test him on a treadmill for 3 days strait in one scene. In another scene the guy has to catch up to trucks so he cut across a forest on foot. Thats all i can remember.
Maybe this?
