The Facts: Peterson is leading multi-hour workouts at his training facility in Houston in an effort to churn out 1,000-yard seasons into his mid-30s.

Diehards Line:In Peterson's mind, he'll be successful longer because he works harder. Should he avoid a catastrophic injury, the typical regression of aging running backs need not apply to him. Age, in Peterson's mind, is a variable that can be controlled. "There’s nothing you can do about [it if] your body starts breaking down and you getting injuries and things like that," Peterson said. "I mean, there are ways to try and prevent that, but I don’t know what [Walter] Payton did going into his last 1,000-yard season. I don’t know what Emmitt [Smith] did. All I know is that from the history I’ve seen, when it comes to athletes, I’ve [seen] so many athletes go way past what people think. That’s the mindset that I have, as well. ..." Highlights of Peterson's day include starting each with a mile run, slated to be seven minutes or better, then starts into a set of nine sprints - six of 300 meters apiece, timed between 42 and 46 seconds, and three at 200 meters each, with a maximum time of 29 seconds. That's followed up by 10 sprints up a 40-degree hill. Then it's on to the sand drill, where players step in a box of four cones -- numbered counterclockwise -- and touch each corner in a sequence barked out by a trainer at random; "2-1-3-4," the trainer shouts, and players stab their feet forward, then back, digging themselves into divots that get more menacing throughout the drill. Next up are three clusters of weight workouts, covering upper-body dumbbell work, planks, bench presses, weighted pullups, rowing and situps, all before a 20-minute core session caps off the workout. Peterson ends several sets with wide eyes, allowing for a brief moment that he's feeling the burn, but according to ESPN.com's Ben Goessling, the RB never lets up. It's not necessarily surprising, but it is comforting for those selecting Peterson early in their drafts.
