Peyton Manning had a NSFW way to see if anyone was watching his workouts

Peyton Manning revealed he wasn't sure if anyone was watching his rehab workouts, so he came up with a way to test it.

As Peyton Manning rehabbed from plantar fasciitis in his left foot last season, he started to have private morning workouts with practice squad receivers and equipment managers. The practices were filmed to help Manning gauge his mechanics as he recovered and show the coaching staff how he was coming along.

But when someone asked him if anyone actually watched his practices or not, Manning didn't know. But he had a great idea to find out if anyone was.

A double one-finger salute is certainly a way to get attention. What got even more attention is the way Manning recovered from the injury to help the Broncos win the Super Bowl.
