Equipped with speed, ability and charisma, Sugar Ray Leonard, filled the boxing void left when Muhammad Ali retired in 1981. With the American public in search of a new boxing superstar, Leonard came along at precisely the right time.
Leonard was named Fighter of the Decade for the 1980s. And why not. He entered the decade a champion and left a champion. In between, he won an unprecedented five world titles in five weight classes and competed in some of the era's most memorable contests.

There were few things Leonard could not do once the bell rang. But what he did best was analyze his opponents and devise a strategy to overcome them. He found a way to beat stylists, sluggers and brawlers. And beneath that flashy surface was a competitor with the remorseless ability to put an opponent away when they were hurt. There were few better finishers in boxing.

JOSEPH LOUIS BARROW, the legendary "Brown Bomber," is considered by many to be the finest heavyweight champion in the history of boxing. He held the world's heavyweight title from June 22, 1937 until June 25, 1948 and made a division-record 25 successful title defenses.

Louis possessed an excellent jab and power in both hands. His right cross was as devastating as his left hook. His punches were so compact that some in the media claimed a Joe Louis punch need only to travel six inches to render an opponent unconscious.

Rocky Marciano is the ONLY undefeated champion in ANY weight class in the history of gloved boxing. Considering how many champions there have been, somewhat over 300, that is quite a feat in itself.

The self-proclaimed "Greatest of All Time," Ali had a pretty good idea of what he was talking about. He became the first man to win the heavyweight title three times and revolutionized the sport by introducing a style that went against many of the game's sacred teachings.

Foreman was young, lean and angry when he beat Joe Frazier for the world heavyweight boxing championship in 1973. The next year he lost the title to Muhammad Ali in the so-called "Rumble in the Jungle" in Zaire. In the 1990s he returned to the public eye as a rotund, jovial fighter who somehow beat Michael Moorer in 1994 to regain the heavyweight crown.

All the sprint training finally has paid off for Roberto.
