This is the guy who was putting the boxing world on it's rear when he was a young kid. At age 19 he was knocking out the best of the best. He trained in a secluded area in up state New York - he had the eye of the tiger.
His physique was built like a mack truck, thick and solid.
His legs were built like tree trunks, and all his jumping rope certainly helped. Juming rope might be the most primitive form of exercise with such a simple tool, but remember, almost all movement begins with the feet. Jumping rope is a form of plyometrics. It also develops stability and strength in the ankles and the entire lower body.
Watching his training still makes me get knocked into my chair. His discipline and fire, his power, his speed, his fierce conditioning!

Time for you to get some training in!
P.S. - Get yourself a jump rope, you just can't go wrong with this simple, yet powerful training tool.
