Jack Johnson, Throwin' The Medicine Ball Around

Jack Johnson, Throwin' The Medicine Ball Around
Medicine Ball exercises have been part of the training programs of oldtime boxers and wrestlers for well over a century because they provide a great workout and build strength in a way that no other piece of equipment can match.

Here's the famous Heavyweight boxing champ Jack Johnson throwin' a medicine ball around a Chicago courtyard circa 1910, in his training to defend the Heavyweight title against Jim Jeffries.

That's a powerful looking man -- Do you think he's getting a workout for the all-important waist muscles? You sure wouldn't want to be on the business end of one of his punches.
