Vikings running back Adrian Peterson wants to add roughly seven to twelve pounds to his frame heading into the 2009 season. "Now is the time of the year to get down and dirty and really start getting after it," said Peterson, who is currently 218 pounds. "God willing [I will get to] 225, 230 just to see how it feels. Before the season starts I look forward to having my weight up so I will be able to see how it is when I run and cut and do different things like that."
