Conor McGregor declares himself Batman as training session leaves him exhausted

Conor McGregor is Batman.

Don't ask why. Just accept that he is, move on with your life and enjoy the sight of 'The Notorious' leaving absolutely everything in the gym in the build-up to his lucrative super-fight with Floyd Mayweather next month. McGregor has understandably abandoned grappling for a few weeks to concentrate solely on stand-up but he has remained faithful to his exhausting strength and conditioning programme. The Irishman kicked his fitness focus up a gear with his camp for the Nate Diaz rematch and it saw him over the line then so if it's not broke, why fix it? McGregor is currently in Las Vegas and juggling his time between the UFC's new Performance Institute and his own boxing gym. https://twitter.com/TheNotoriousMMA/status/890442533729296384 And it's easy to tell that the 29-year-old is certainly not slacking off in training, as he leaves the gym exhausted several times a day. On Thursday morning, McGregor posted footage of himself enduring a gruelling session on a rowing machine while his team watched on, before he sped off into the desert night. https://twitter.com/TheNotoriousMMA/status/890527215514824705 McGregor believes that his boxing debut, against arguably the greatest pugilist of all time, will actually be an easier test of his conditioning than any of his mixed martial arts contests to date. "You’re talking about a 200lbs man there [in the Octagon]," McGregor said on the recent promotional world tour. "You’re talking about grappling exchanges. You’re talking about elbows, knees, kicks. You’re talking about a hell of a different contest. "A little boxing fight where there’s a referee to save the day every time there’s a tie-up and a clinch? Twelve three minutes is nothing. I don’t mean to be disrespectful, but this game is very easy. It’s a very easy game compared to my game."
