Essential Preperation
Training is essential preparation for providing the strength and endurance needed for boxing. Success in competition is directly proportionate to the amount of effort that is put into training.
Training should be conducted at a rapid pace to train the body, particularly the cardiovascular system, for quick, explosive action. Currently in amateur boxing, bouts are four rounds long which does not leave time for “feeling out” your opponent or pacing yourself.
A professional boxer needs to train at a rapid pace also. I can't imagine a fighter being in the ring enjoying just being there and bouncing around. It's a different story when you are in the ring and you have a game plan. A boxer should train for the same duration in which he is going to compete.
All too often a professional boxer working three minute rounds conditions his body to work at 80% of its physical potential. Unfortunately, when 100% is needed in competition, he is not prepared for it. The key is to train at the same duration as competition and at 100% (Plus) intensity. Most gyms are open only three nights a week which is adequate and keeps the coach and boxers from getting burned out.
To complement the gym work, an aspiring champion must workout two or three additional days of the week. Your better, more dedicated boxers should be shadowboxing, and running when they are not working in the gym.
