Conor McGregor’s training videos leading up to his fight against Floyd Mayweather have been … unconventional, to say the least. Boxing analysts have mocked his lack of speed and his footwork, while fellow fighters have gravitated towards one of his moves.

McGregor’s noodle arms aren’t a new thing. The fighter has done this in the past, but more people are noticing with the spotlight being brighter on him than ever before. In turn, his fellow fighters are taking a page out of this training book and turning it into “The Conor McGregor Challenge.”

Even Muay Thai fighters are getting in on it:

This martial artist thinks he has it all figured out … NUNCHUCKS!

The caption to this one is the only example of anyone praising McGregor’s weird method.

The secret behind Conor mcgregor training movement….nunchucks attack ! but seriously, this movement is great for warmup, coordination and mainly to practice your looseness.

Is McGregor’s technique a secret weapon other fighters don’t understand? We’ll have to wait to see who has the last laugh after the fight.
