SAUL "CANELO" ALVEREZ underwent an amazing body transformation as he rose from skinny welterweight and super-middleweight.
31-year-old Mexican pound-for pound king has plowed through the super-middleweight category since December, when he was back at 168lbs.
Canelo is absolutely gorgeous as he prepares for Caleb Plant's fight
Callum Smith was defeated by Canelo, who won the WBA title. Canelo then beat Avni Yildirim in February before stopping Billy Joe Saunders May.
He defeated BJS to become a WBA, WBC, and WBO champion. Now, he needs only the IBF to be undisputed.
This opportunity will be available on November 6, when he takes on bitter rival Caleb Plant at Las Vegas' MGM Grand.
However, Canelo was already a LIGHT-HEAVYWEIGHT and had jumped from middleweight to light-heavyweight to defeat Sergey Kovalev in 2019.
He was joined by Juan Manuel Marquez and Jorge Arce, the four-division world champions from Mexico, for this win.
Alvarez, who began his career at 15 years old, fluctuated in his weight. He fought at 140lbs light-welterweight before finally settling down at welterweight.
SunSport examines Canelo's dramatic body transformation after he won his first title at light-middleweight.
WELTERWEIGHT
Alvarez won 33 fights and made his US debut against Larry Mosley on October 2008. He then won another Stateside victory before going back to Mexico for a further two years and nine fights.
He returned to defend his NABF welterweight title, against Jose Cotto. It was his last fight at 147lbs.
LIGHT-MIDDLEWEIGHT
Canelo won the first world title at 154lbs, beating Ricky Hatton's brother Matthew from California.
Although the Mexican won points, he was significantly smaller in body and bulk than before with a baby-face.
He would defend the WBC belt five times before unifying against Austin Trout, who also claimed the WBA strap in April 2013.
Canelo, who was 23 years old, would defend his light-middleweight title against Floyd Mayweather. However, he had to lose on the scales.
FLOYD MAYWEATHER
Mayweather did not move up from welterweight in order to face Oscar De La Hoya or Miguel Cotto. However, he did so again to face rising star Canelo on September 2013.
Alvarez was forced to sign stipulations by the American boxing legend - who managed and promoted himself.
Canelo claims that Mayweather tried to include a rehydration clause into the contract.
Mayweather was reportedly 150 lbs below his weight. Alvarez was 165 lbs and gained almost a stone. But Alvarez still beat him.
MIDDLEWEIGHT
Canelo climbed up to middleweight after his first defeat and was taught by Mayweather how to use his star power.
Despite being in the 160 lbs division, the Mexican hero made his opponents fight at a catchweight weight of 155lbs. He won the The Ring, Lineal and WBC titles against Cotto.
Brit Amir Khan moved up to middleweight at 155lbs to face Canelo, but was brutally knocked out in six rounds. Alvarez then moved back to lightweight to take the WBO title from Merseysider Liam Smith.
After being ordered by the WBC to face GennadyGolovkin, he only dropped to 154lbs. However, De La Hoya maintained that his man wasn't yet a true middleweight.
Smith was defeated by Canelo in the final fight at 154lbs.
De La Hoya claimed that the Mexican wasn't ready to box at 160lbs. However, Alvarez would fight Julio Cesar Chavez Jr. in a 164.5lbs catchweight bout. This was ABOVE the limit for middleweight.
This fight was used to test Canelo's matchup against GGG at middleweight, and Chavez Jr was easily defeated.
SUPER-MIDDLEWEIGHT
Canelo announced a change to 168lbs in order to face Brit Rocky Fielding after two contentious bouts against Golvokin at Middleweight.
The Mexican would be challenging for the WBA's super-middleweight understudy world title. He won it with ease in just three rounds.
Canelo, who was much smaller than Fielding, targeted Fielding's body in order to win a title at the third weight of the world. He then said he was open to fighting Smith for the title.
Canelo won a super-middleweight title and was able to return to 160lbs. He will now face Daniel Jacobs, who holds the IBF title.
Alvarez was able to move eight pounds back without affecting his reflexes or power. He displayed great aggression and defence on the way of a points victory.
Jacobs refused to comply with the IBF's 170lbs rehydration provision, and Canelo complied. Jacobs lost his belt for tactical reasons, coming in at 173.6lbs.
Alvarez, who had just added another middleweight belt in his collection, decided to not defend them against Golovkin in a three-round bout.
He instead replicated US legends like Roy Jones Jr., Bernard Hopkins, and Sugar Ray Leonard, who all won 175lbs titles.
Canelo said he would keep the weight after defeating Kovalev but instead, he slipped back down to super-middleweight to fight Smith.
FOUR-DIVISION CHAMP
After weighing in at the 168lb limit, Canelo established himself as a four-division champion.
Two years after their secondary 'Regular" title, the Mexican star won the WBA super middleweight crown.
Smith was too powerful and precise for Canelo and he won easily after twelve close-fought rounds in Texas.
In February, he defended the titles against Avni Yoldirim and beat Billy Joe Saunders to win his fourth belt at supermiddle.
He is now looking to add Plant in Vegas to his collection.
