There are two things in a Conor McGregor weigh-in that may surprise you. Firstly, is his choice of haircut and secondly, and more importantly, the exact weight he has chosen to fight at.He is renowned for his incredible weight cutting and his ability to move up and down weight classes in order to fight certain fighters.His lowest recorded weigh-in came in at 145-146lbs on six different occasions when he fought Marcus Brimage, Max Holloway, Diego Brandao, Dustin Poirier, Chad Mendes and Jose Aldo. This weight lasted over a two-and-a-half-year period.Following this gruelling stage, he jumped up two weight categories to 168lbs in the short space of three months in order to begin his infamous feud with Nate Diaz in their very first fight at UFC 196.In their returning fight, following the Irishman's loss, he remained at the same weight to contest Diaz again whilst looking for revenge. This was a fight he would go on to win.In the very same year, McGregor fought Eddie Alvarez at UFC 205, where he would drop to 154.5lbs, but still looked in phenomenal shape.

Until the beginning of 2020, he would remain around a similar weight and body stature until he met with Donald Cerrone, where he would be seen weighing in at a career-high of 170lbs.

In his final two fights to conclude his beef with Poirier, Notorious weighed 155 and 156lbs, respectively.

It is common knowledge that the process of weight cutting has its serious repercussions and that fighters should be very careful and always under the supervision of medical professionals.

His coach has even reportedly admitted that the UFC star’s weight was “extreme” and “unhealthy” and has shared their happiness that he no longer cuts down to 145lbs to make a weight category.

His ability to change weight drastically to the manner he is able to made him become the first fighter to hold titles in two different weight classes simultaneously.
