UFC featherweight champion Conor McGregor is currently gearing up for his UFC 202 welterweight rematch with Nate Diaz this Saturday.

Ahead of the fight, McGregor has been very open about the fact that he is focusing on his cardio for the fight so as to not gas out in the rematch like he did in the first round of the pair’s first fight.

In the video above, you can see McGregor killing a treadmill workout as part of his ‘This is the Mac Life’ video series.
