The center of your boxing universe isn’t the center at all, but actually begins on the ball of your back foot. You’ve undoubtedly heard the phrase before that power starts from the ground up. That’s true, except power really emanates from the point of contact with the ground and that point of contact originates in the big toe and/or at the ball of your back foot.
The big toe carries the most weight of all the toes, bearing about 40% of the load of your body weight. By not driving off the ball of your back foot, you are, in essence, utilizing 40 percent less power/leverage than if you were to point and dig with that toe when delivering punches.
