It is important for football players to increase their neck strength in order to be better prepared to play the game. This was a fact not lot on “Da Bears” as shown by this rare training camp shot. Check out the guys bridging in the background, and yes, that’s Mike Ditka himself doing a headstand. Look closely and you’ll see that his whistle has fallen down around his face. If you have no other equipment available, a simple headstand like this can be an excellent method for building neck strength.
