When new boxers start talking about 'bulking up", I like to remind them of the great fighters who did not bulk up and concentrated on power punching. The great John L. Sullivan , who was a bare knucle heavyweight champion for over 7 years was at his best fighting weight at 190. He defended his title against Jake Kilrain in a fight that lasted 75 rounds over two hours and fifteen minutes. Jack Dempsey was a small guy by todays standards. The "Manassa Mauler" was a power puncher. In his 70's two young criminals decided to mug him..he threw two punches and knocked both of them out. In 1919 Dempsey, who stood 6 feet and weighted 180 lbs, challenged for the heavy weight title held by Jess Willard, who stood 6'6" and weighted 245 lbs of muscle. In one round, Dempsey knocked Willard down 7 times. In the fight, Dempsey hit so hard that he broke Willards Jaw, cheek bone, and several ribs. Willard collapsed in his corner between the 3rd and 4th round. Bob Fitzsimmons was called a 'fighting machine on stilts' because he stood 6" tall with long legs and lanky frame and weighted less than 170 lbs. He held heavyweight, middleweight and lightweight crowns and was known as a vicious hitter. Rocky Marciano at 190 lbs was known as the hardes right-hand punch ever seen. People think they can hit because they have big muscles..it's not true. My advice is to take the time you spend on weights and concentrate on power punching. In a fight---bet on the fighter, not the muscle man.
