McGregor has put on muscle during his recovery and looks a lot bulkier

UFC DEBUT – 2013

McGregor looked flawless in his UFC debut, quickly knocking out Marcus Brimage in Stockholm to announce himself to the world of MMA.

The 24-year-old has caught the attention of fight fans not only for his impressive display and charismatic personality, but also for his size as a featherweight.

One look at the 5-foot-9 youngster would tell you he struggled to gain 145 pounds, but that didn’t stop him from performing at the weight.

McGregor moved from Cage Warriors to UFC featherweight division and scored first knockout in 2013

Dustin Poirier’s first fight – 2014

In 2014, McGregor was starting to become a superstar in the sport and saw the UFC host an event in his hometown of Dublin.

After beating Diego Brandao by knockout in the first round, he fought against one of the biggest fish in featherweight – Dustin Poirier.

He quickly sent it too and proved it was legit.

During this time, McGregor’s hairstyle changed often, but his body remained the same despite a few additional tattoos. He continued to look like one of the biggest featherweights you’ve ever seen and a weight increase seemed inevitable, but he had things to do first.

Chad Mendes, Jose Aldo and UFC gold – 2015

After easily knocking out disappointing opponent Denis Siver, McGregor faced serious opposition in his next two bouts.

He first won the interim featherweight title by stopping Chad Mendes in the second round of their fight before unifying the division with a dramatic one-punch knockout win over fighting legend Jose Aldo.

After realizing his primary dream of becoming champion, McGregor ended his featherweight run as each weight cut became more difficult than the last.

But those weight cuts were getting harder and harder and her days at 145 pounds were numbered.

Even McGregor weigh-ins are box office attractions

“Notorious” suffered a monumental loss when he jumped 25 pounds to face Nate Diaz at welterweight just days before in March at UFC 196 when Rafael Dos Anjos pulled out with an injury. He lost but, after a full camp, McGregor fought Diaz again at 170 pounds and avenged the loss a few months later in August.

After that, he made his lightweight debut in November and looked exemplary while making history against champion Eddie Alvarez, becoming the first-ever UFC champion to hold two belts simultaneously.

Many suspected that 155 pounds was McGregor’s true home and it’s hard to argue after watching his performance and seeing how good he looked on the scale.

Floyd Mayweather – 2017

A mega-money crossover fight with Floyd Mayweather was the only time McGregor competed in August 2017 and he reached the slightly lighter scale (154 pounds) than his career-best win 11 months earlier.

Although he appears to be in great shape, a boxing debut against arguably the greatest fighter of all time was too much for ‘Notorious’ who suffered a tenth-round TKO loss.

Khabib Nurmagomedov – 2018

After a two-year absence from his first sport, McGregor returned for a grudge match against his biggest rival, Khabib Nurmagomedov.

The accumulation was bitter and unpleasant. McGregor was out of his game in terms of trash talk and it all translated into the fight.

Although he looked ready at 155 pounds, he was outclassed by “The Eagle” who has since established himself as the greatest lightweight fighter of all time.

Dustin Poirier Gets Revenge – 2021

Despite looking and feeling so good at welterweight, McGregor returned to lightweight to settle another rivalry, this time with Poirier, whom he had beaten at the peak of his powers.

The pair fought twice in 2021 and although McGregor’s mood seriously differed with each bout, his physique remained spot on but his performance left a lot to be desired.

After suffering a TKO loss to Poirier at UFC 257 in January, he suffered a catastrophic leg injury at UFC 264 a few months later. The one that has kept him away ever since.

Bigger than it’s ever been – 2022

During his time away from the sport, McGregor bulked up seriously, and at one point in his rehabilitation, he hit 190 pounds of pure muscle.

It seems like he likes to carry extra weight, because when he returns to action, it will be at welterweight.

He has now returned to action for the first time since UFC 264 and looked in terrifyingly huge form as he took on his partner at the Crumlin Boxing Gym.
