In this piece, our major concern is the weight of boxers and we’ll be looking at the heaviest heavyweight boxers of all time.

Read on to learn more about these beasts:

1. Eric Esch

In addition to boxing, Esch has also wrestled and fought in the MMA and mixed martial arts. He is a well-known TV personality who has been on and been cited on several occasions.

After a successful Toughman Contest career, Esch became professional in 1994 and won the WAA heavyweight and IBA super heavyweight titles. He competed in kickboxing and MMA in K-1 and the Pride Fighting Championships.

He is also known under the name Butterbean and has a 97–24–5 record with 65 knockouts and 9 submissions.

With a 171 kg weight, he is a heavyweight legend.

2. Nikolai Valuev

Nikolai Sergeyevich Valuev, a Russian politician, and the former professional boxer was born in Moscow on August 21, 1973.

He was the WBA heavyweight champion twice between 2005 and 2009, and he was a boxer from 1993 to 2009. Valuev announced his retirement from boxing in a Russian newspaper three days after losing to Haye.

In 2010, it was revealed that Valuev’s doctor was treating Valuev for “serious bone and joint difficulties.” After having two surgeries, Valuev was forced to miss at least six months of work.

Valuev said in 2013 that he will not return to the ring due to medical advice. With heights of 2.13 meters (7.0 feet) and a maximum weight of 149 kilos, Valuev holds the records for both the tallest and heaviest world champion in boxing history (328 pounds).

3. Tyson Fury

Luke Fury, a Tyson professional boxer, was born on August 12th, 1988 in London, United Kingdom.

Since his victory against Deontay Wilder in 2020, he has held the WBC and The Ring magazine titles; he previously held the unified WBA (Super), IBF, WBO (I), and The Ring crowns following his victory over Wladimir Klitschko in 2015. He has two world heavyweight titles.

The only other heavyweights who have held The Ring magazine title twice are Floyd Patterson and Muhammad Ali. After beating Wilder, Fury is widely regarded as the lineal heavyweight champion.

ESPN rates Fury as the best current heavyweight and one of the heaviest heavyweight boxers of all time with 126 kg in November 2021.

4. Riddick Bowe

Riddick Lamont Bowe (born August 10, 1967) was an American boxer from 1989 through 2008. At the 1988 Summer Olympics, he earned a silver medal for the USA in super heavyweight.

Bowe became a two-time world heavyweight champion in 1989. In 1992, he defeated then-unbeaten heavyweight champion Evander Holyfield to win the WBA, WBC, and IBF crowns.

In the same year, he won his first world championship, Bowe was awarded Fighter of the Year by The Ring and the BWAA. World heavyweight champion Bowe weighs 123 kg.

5. Andy Ruiz

Ruiz reached his maximum weight for the first fight after attaining it for his rematch with Anthony Joshua, which he lost by unanimous decision.

When he stopped Joshua in their first bout, he weighed 268 pounds (121.6 kg) and became the first man to carry the title of unified champion. Ruiz’s substantial weight is commonly thought to have hurt him the second time around.

6. Shannon Briggs

The WBO heavyweight championship was held by Briggs for seven months between 2006 and 2007. Then he was at his heaviest throughout this period.

Before losing it against Sultan Ibragimov on points at 273 (123.8 kg), he had won the belt by stopping Siarhei Liakhovich in 12 rounds.

7. Primo Carnera

Carnera moved swiftly for a man of his height, but his success was due more to his links to the mafia than anything else.

Despite being outweighed by more than 50 pounds, Max Baer humiliated the gigantic Italian, knocking him down up to 10 times (records are unknown) and halting him in Round 11 to win the title.

He weighs 129 kg, making him one of the world’s largest heavyweight boxers.

8. Anthony Joshua

When Andy Ruiz Jr. knocked Joshua out in the first round at 113 kg, Joshua decided that a smaller opponent would be more effective, so he lost 107 kg for the rematch.

He weighed 108 kg when he met Kubrat Pulev and won by KO. That is, as far as I can determine, his ideal weight.

9. Jess Willard

The Pottawatomie (Kansas) Giant won his first title by defeating the great but ailing Jack Johnson, then put on weight for his only successful defense (against Frank Moran) before being knocked down seven times in the first round and suffering a terrible beating by Jack Dempsey to lose his title in three rounds.

Jess Willard, who weighs 118 kg, is among the world’s heaviest heavyweight fighters.

10. Lewis Lennox

Lewis was able to reach his peak weight when facing Vitali Klitschko in his final six-round contest because Klitschko was unable to continue due to a nasty cut. Lewis, a three-time world champion, announced his retirement after the war.

He’s also one of the world’s heaviest heavyweights, weighing 118 kg!

11. Vitali Klitschko 

Vitali Klitschko Sr. maintained an astounding degree of consistency over the last decade of his career at 245-250 pounds.

That demonstrates his dedication to his career. He weighed 144 kg and was knocked out in the 10th round of his fight with Chris Arreola after which he resigned as heavyweight champion.

12. George Foreman

After a 10-year sabbatical from the sport, Big George was a completely different person. This variant weighed in at 99-101 kg.

In 1987, he weighed 121 kg in his first bout against Steve Zouski. Michael Moorer’s defeat and Axel Schulz’s championship defense proved he was in better shape.
