Boxer Riddick Bowe made it through 11 whole days of regular basic training a few years ago before he quit. Said they didn't give him enough to eat.

"[During training] the other Rangers will literally try to run him into the ground," Parker said. "They'll respect him for giving up pro football, but they won't show him any favoritism.
