Arizona Cardinals' Robert Gill Hits 25mph On Treadmill (VIDEO)

Arizona Cardinals rookie Robert Gill has yet to prove himself in the NFL, but if there's a treadmill race anytime soon he will be tough to beat.

Gill gets on a treadmill revved up to 25 miles-an-hour and shows off the electric feet which convinced Arizona to give him a tryout at the grand old age of 29.

After his Superman impression, there are the obligatory testosterone-fuelled celebrations, akin to White Goodman in Dodgeball.

He certainly fares better in the gym than Bill Murray on a cross-trainer.
