Dez Bryant may not have been credited with a catch against the Packers, but it wasn't because he's not in good shape. 

Bryant posted a pair of videos on Instagram Thursday of him performing incredible feats of strength.

• Aaron Rodgers' brother was a seat filler at NFL awards show

It's impressive, but it's still not a football move.
