Robert Gill’s treadmill video, which shows the Arizona Cardinals rookie running 25 miles, turned viral last week.
The YouTube video left some users in amazement.
“Just stepping onto and back off a treadmill running 25 miles an hour is? quite impressive, let alone running on it for 5 seconds. A 100 percent stud,” user “Jscussel” wrote.
Gill, who is 29 years old and spent the past five years playing in the Arena Football League, posted a 4.17-second 40-yard-dash, according to The Inquisitr website.
