Rising from humble beginnings, McGregor’s journey to fame and influence in MMA has captivated fans worldwide, and it all started with his exploration of different weight classes.

Featherweight Division: McGregor’s Early Dominance

In the early days of his career, McGregor made his presence felt in the featherweight division, weighing in at 145 pounds. This weight class became his playground for showcasing his unparalleled talent and skill in the octagon.

With a unique blend of precision striking, relentless pressure, and unshakeable self-belief, McGregor quickly established himself as a force to be reckoned with.

Lightweight Division: The Double Champ Ambition

With his dominance established in the featherweight division, McGregor set his sights on a new challenge – becoming a double champ by conquering the lightweight division. An opportunity to test his skills against larger opponents and solidify his status as a legend beckoned him.

In his lightweight debut, McGregor faced Eddie Alvarez in November 2016.

The Jump to Welterweight: Seeking New Challenges

Never one to shy away from stepping outside his comfort zone, McGregor made the daring decision to compete in the welterweight division, which allows fighters weighing up to 170 pounds. This move opened up a new realm of possibilities and presented him with exciting challenges against bigger opponents.

In his welterweight debut, McGregor faced Nate Diaz in March 2016. Although the fight resulted in a submission loss for McGregor, it showcased his resilience and proved that he could hold his own against larger foes. McGregor’s willingness to take on such formidable opponents in higher weight classes demonstrated his relentless pursuit of greatness.
