Steelers OLB James Harrison does sprints in the extreme heat...with a weighted vest
For those that don't know, artificial turf gets much hotter than just regular turf. In Arizona in late June, you can imagine how hot it can get. Steelers OLB James Harrison has returned to the desert to train for the upcoming season, and he is working hard in the heat. In this video he is doing sprints on a field measuring over 180 degrees...while using a weighted vest. Some might see Harrison as crazy, while the rest of us see him as dedicated on winning another Super Bowl.
