Adrian Peterson, star running back for the Minnesota Vikings, suffered a torn ACL in December 2011. As part of Peterson's regiment to rehab his injured knee, he played Wii Fit and other specially-designed games to regain strength and balance.

As seen in a video on the team's site, Peterson uses a leg press machine to guide an on-screen icon through a maze of boxes in one game, and dodge falling balls in another. The exercise machine strengthens his knee while also providing him with something other than agonizing pain to focus on. With the high-powered training programs they're used to, it's interesting to see a pro football player include games like these as part of their recovery methods.
