The 10 Biggest Mass Monster Bodybuilders of the 1990s

Olympia champs and Sandow hopefuls line our list of the biggest of the big.

Written by Roger Lockridge
Last updated on April 3rd, 2025

Many bodybuilding fans remember the 1990s as the sport’s peak due to the next-level shape and conditioning of the athletes archetyped as “Mass Monsters.”

The ‘90s saw a shift in the sport. Athletes packed on more and more mass, oftentimes reaching 300 pounds on stage. Their unreal size helped a generation of athletes find new levels of success on stage, with many still talked about in modern day. Below is a list of 10 bodybuilders who epitomized the Mass Monster era.

10 Biggest 1990s Mass Monster Bodybuilders

  • Dorian Yates
  • Lou Ferrigno
  • Paul Dillett
  • Nasser El Sonbaty
  • Greg Kovacs
  • Ronnie Coleman
  • Gunter Schlierkamp
  • Markus Ruhl
  • Jean-Pierre Fux
  • Dennis James

Dorian Yates

Dorian Yates was an imposing presence in the bodybuilding scene at the start of the decade. He elevated his status at the 1991 Mr. Olympia by going toe-to-toe against the legendary Lee Haney. Though Haney was crowned champion and retired as an eight-time Mr. Olympia, the bodybuilding world was on notice — the next dynasty was forged in England.

Yates returned to the Olympia in 1992 to win the title, signaling the kickoff of a new era. Competing at around 260 pounds, “The Shadow” made clear that competing on stage against him required being big and shredded. 

Few athletes came close to dethroning Yates. Injuries compelled Yates’ retirement in 1998, but his presence in the sport impacted the course of bodybuilding.

Lou Ferrigno

Lou Ferrigno was considered a bodybuilding icon in the ‘90s thanks to his roles in the films Pumping Iron and The Incredible Hulk and his two Mr. Universe titles in the 1970s. However, the sport’s ultimate prize, the Mr. Olympia, eluded him. Ferrigno returned to the stage to put a bow on his bodybuilding career. 

Standing 6-foot-4 inches and weighing over 270 pounds, Ferrigno was among the biggest bodybuilders during his ‘70s heyday. He felt he had to be bigger to stand a chance against the new era of ‘90s talent.

Ferrigno bulked to something fierce, tipping the scales at 290 pounds for his hulking comeback at the 1992 Mr. Olympia in Helsinki, Finland. He finished in 12th place; Yates claimed the title.

Ferrigno entered the 1993 Mr. Olympia contest even bigger than the year prior, weighing approximately 300 pounds. He finished 10th overall. Yates won again.

Ferrigno’s career ended at the 1994 Masters Olympia when he banked on his size to earn him victory. The leaner and better-conditioned Robby Robinson pulled the upset, relegating Ferrigno to second place in his final contest.

Paul Dillett

Paul Dillett entered the IFBB in 1992 He quickly became a force after finishing in the top six at the 1993 Mr. Olympia. Dillett’s size and vascularity stood out on stage. He often got as big as 320 pounds in the off-season — unheard of at the time. 

Despite his size, Dillett was not considered the best poser, the reason many experts felt prevented him from reaching the top of the podium. That criticism turned to concern in 1994 when he “froze” at that year’s Arnold Classic due to dehydration; he had to be carried off stage.

Dillett saw some success during his career, including a win at the 1999 Night of Champions (now New York Pro). He finished as high as fourth at the Olympia in 1994. Dillett retired officially in 2012 and owns the World Beauty and Fitness Fashion (WBFF) organization as of 2024.

Nasser El Sonbaty

Before Mamdouh “Big Ramy” Elssbiay was a force in the sport through the 2010s and early 2020s, Nasser El Sonbaty was considered the greatest bodybuilder from Egypt.

El Sonbaty had the size and shape that warranted a loyal fanbase since his pro debut in 1990. He found success in 1993 via a bronze medal at Grand Prix France and Grand Prix Germany contests. 

https://www.youtube.com/watch?v=bsyF5tcrnoo

El Sonbaty’s Olympia debut in 1994 resulted in a seventh-place finish. His first pro show win came at the 1995 Houston Pro Invitational. Soon after, speculation that he could match Yates’ size and conditioning circulated.

The inevitable matchup occurred at the 1997 Mr. Olympia. While Yates won his sixth and final Sandow, many fans felt El Sonbaty and his nearly 300 pounds of shredded mass was the better package.

The Egyptian sensation went on to win the 1999 Arnold Classic but never saw the same level of success thereafter. His final pro show was in 2005. He passed away in 2013 at age 48.

Greg Kovacs

Canadian fans who saw Dillett may have thought bodybuilders couldn’t get any bigger, but they did not see Greg Kovacs coming. In an era of mass monsters, Kovacs was considered bodybuilding’s Mount Everest.

The Ontario native stood 6-foot-4 inches and claimed to compete at 330 pounds (he reached over 400 pounds in his off-season.) Kovacs’ sheer size earned him enough attention to garner magazine covers.

Kovacs earned pro status at the 1996 Canadian National Championships, but couldn’t translate his size into on-stage success. He never cracked a top-10 finish in any pro show, but his mammoth physique and heavy gym lifts earned him a cult following. Kovacs died in November 2013, three weeks shy of his 45th birthday.

Ronnie Coleman

Many fans consider Ronnie Coleman the greatest bodybuilder of all time. Coleman began his legendary run in the early ’90s.

Even though Coleman was not the biggest athlete onstage early in his career, he had incredible density and cartoonishly large arms. At 5-foot-11 inches, Coleman regularly competed in the 260-pound range during the middle of the decade.

An important part of Coleman’s legacy came when he beefed up from 1997 to 1998. The improvements moved Coleman from ninth at the 1997 Mr. Olympia to the top of the podium in 1998. The added bulk, in part, is credited to Coleman’s new coach, Chad Nicholls, who helped “The King” climb to the top of the bodybuilding world and inevitably become the sport’s biggest star.

Coleman was his biggest in 2004, stepping on the Olympia stage reportedly weighing 296 pounds. Soon after that Olympia, Coleman competed overseas weighing over 300 pounds. His on-stage size and strength in the gym garnered legendary status that fans still talk about nearly two decades after he retired from competition.

Gunter Schlierkamp

Even though Gunter Schlierkamp was not as successful on stage as some of the previously mentioned mass monsters, his charismatic personality and unreal size made him a mainstay in the muscle magazines of the era. The German beast weighed over 300 pounds in the off-season and epitomized the era’s aesthetic.

Schlierkamp’s popularity was rewarded when he pulled off the first “upset of the century” in 2002, defeating Ronnie Coleman in that year’s Show of Strength contest following Coleman’s win at the 2002 Mr. Olympia. That win elevated Schlierkamp as the top contender for the 2003 Mr. Olympia title. However, a vengeful Coleman entered the 2003 Olympia with his largest package up til then to keep the Sandow trophy. Schlierkamp finished Olympia in fifth place.

Markus Ruhl

A quick look at Markus Ruhl makes one thing clear: This was not a symmetrically artful physique. Ruhl was the pinnacle mass and grew to over 300 pounds at his biggest.

Ruhl competed in the range of 270 pounds. His enormous traps, shoulders, chest, and arms made him a fan favorite on stage and magazine covers.

Ruhl won pro shows due to his definition and conditioning, including the 2000 Toronto Pro and 2002 Night of Champions. His best finish on the Olympia stage was fifth in 2004. He retired from the sport in 2010.

Jean-Pierre Fux

At 6 feet tall and competing at approximately 275 pounds, Jean-Pierre Fux was a huge athlete en route to superstardom. He turned pro at the 1994 World Championships and would reportedly eclipse 300 pounds in his off-seasons. His seventh-place finish at the 1997 Olympia was a sign of a bright future in the sport.

That all changed in 2002 when Fux suffered a quad injury while performing a 675-pound squat for a FLEX Magazine photo shoot. Fux’s competitive career ended as a result. He remains one of the biggest “what-ifs” of the era.

Dennis James

Dennis “DJ” James emerged at the end of the decade for his size and shape, which was considered one of the world’s best by the time he earned pro status in 1998. This was validated by various photo shoots that featured him posing while training in a gym.

Unfortunately, James never reached the pinnacle of the sport but was in the mix at several Olympias while competing in the 255-265 pound range. He finished 10th in his final Mr. Olympia contest in 2011. He emerged from retirement once to enter the Masters Olympia in 2012 and finished in the top three.
