I'm all for showing off your 40 time and fast-twitch muscle fibers, but this is straight up ridiculous. Robert Gill is a 29-year-old rookie receiver with the Arizona Cardinals. Despite his world-class speed, it still took him a while to latch onto an NFL roster. If he'd taken one false step on that treadmill, it would have ended before it even started.
Peer pressure is something else, but there are better ways to show off in front of your teammates.
