Chad Johnson isn't going to let anyone on the Internet upstage him.
Arizona Cardinals 29-year-old rookie Robert Gill's incredible video of him running 25 miles per hour on a treadmill recently went viral. It was even on the "Today" show, which means it really hit the big time.
Johnson, who is still looking for work in the NFL but never misses a chance to put on a show, ran 24 miles an hour on a 2.5 percent incline, according to the video (h/t to NFL Reddit, via Yardbarker.com).
Now, this doesn't mean that Johnson should get another job or anything, but it is a pretty impressive feat.
No matter if this becomes a fad among NFL players, DO NOT try this at home. If you do, there's a pretty good chance you'll end up like this (and if you do, please send Shutdown the video). Play him off ...
