Tim Tebow Works 'Lip Sync Battle' Stage as Rocky Performing 'Eye of the Tiger'

After quite some time, two things about Tim Tebow, retired NFL quarterback, still remain the same: He's in outstanding physical shape, and his inner willpower is unrelenting.

Both were on display as the former Florida Gator channeled his inner Rocky Balboa during a particularly sweaty "Eye of the Tiger" rendition on Lip Sync Battle.

Throwing jabs, jumping rope and giving the prop meat a few punches, Tebow worked the stage and the crowd.

One might even say that he looked very at ease; so comfortable, in fact, that he even tossed off his hoodie and flexed.

Say, Tim, this isn't your Magic Mike audition tape, is it?
