07:01 AM ET 06.28 | Credit Robert Gill for finding a way to get his name out there, so to speak, with a little bit of self-promotion. [Gill] is a 29-year-old rookie who will attempt to catch on with the Arizona Cardinals in training camp. Until then, the wide receiver can enjoy his status as a viral video star. Gill recently posted a video on YouTube in which he sprints on a treadmill at 25 miles per hour. It's completely insane. Far be it from us to criticize how a professional athlete chooses to train, but this seems to be a good way to make your hamstrings explode. Then again, 6.3 on the treadmill represents our personal panic zone.
