Terence Crawford looks to be in sensational shape as his super fight with Canelo Alvarez draws near.‘Bud’ will jump up two weight classes on September 13 to challenge Canelo for his undisputed super middleweight crown in Las Vegas.Instagram - Terence CrawfordCrawford looks like a natural super middleweight in pictures from camp[/caption]Crawford has never boxed higher than super welterweight (154lbs), and so he has piled on a considerable amount of muscle mass in order to fit into his super middleweight (168lbs) frame.He is reportedly walking around at 185lbs six weeks out from fight night, after tipping the scales at close to the cruiserweight limit (200lbs) earlier this year.Recent pictures posted by Crawford from his camp show him to be significantly bulkier than he was when he was operating at a lower weight.Despite this, he is still flaunting a ripped physique, complete with washboard abs.His muscular tone shows that Crawford has spent his 12 months out of the ring, properly acclimating to his new weight.A shirtless snap with the caption, ‘Ain’t no stopping me’, caught the attention of boxing fans who flooded the comment section with praise.Reacting to the photo, one supporter wrote: “Bud staying at 168 after the Canelo fight.”Another added: “Bud is huge… Pause.”A third posted: “Damn sure won’t look like the smaller guy, watch.”A fourth commented: “Boy looking huge.”Crawford has put on a lot of muscle mass since he was last in the ring 12 months agoGettyCrawford challenges Canelo for his undisputed super middleweight crown on September 13GettyMeanwhile, somebody else remarked: “Crawford is a serious super middleweight.”Crawford last fought in August 2024, when he picked a hard-fought unanimous decision win over Israil Madrimov to lay claim to the WBA super welterweight crown.While he is still a belt holder at 154lbs, few expect him to return to the weight class.At 37 years old, Crawford is entering the twilight of his career, and several members of the boxing fraternity anticipate that he will hang up his gloves after his showdown with Canelo.If he can overcome the odds and beat the Mexican superstar, then he will be crowned the first male three-weight undisputed champion in the four-belt era after previously reigning supreme over the super lightweight and welterweight divisions.A victory would also likely see him leapfrog Naoya Inoue and Oleksandr Usyk to the top spot in boxing’s pound-for-pound rankings.
