"Conor improves on a daily basis. The Conor of today is better than the Conor of yesterday," his coach Owen Roddy exclusively told Sky Sports. "He gets better every day, every week
"The camp is not too different. It hasn't really changed. In Conor's MMA fights the plan is to keep it standing, and knock the opponent out. So that hasn't changed. We're limited with the weapons we can use, but we're trying to lead the opponent into Conor's shot."
"We're training five-and-a-half or six days a week," said Julian Dalby, the sports scientist who oversees the 'McGregor F.A.S.T Extreme performance training plan'.
"It stands for Fighter Anaerobic System of Training. It combines high-intensity aerobic training with continuous, endurance training so it's ideally suited to MMA but also lends itself to boxing.
"The fitness required for boxing is not radically different to MMA. It isn't a 100m sprint compared to middle-distance running. There are more strikes thrown in boxing than MMA so it's a more continuous power output. MMA requires higher anaerobic peak outputs for takedowns.
"Typically Conor does skills-based training early in the day, then conditioning training later so he doesn't have to hold back. Traditionally an athlete might do both together so they hold back.
"At this weight, there is a slight trade-off with his maximum power but an increase in his VO2 Max (his ability to perform consistently)."
"On an average day, he eats nine times," said McGregor's nutritionist George Lockhart. "It's insane how amazing his body is looking. We give him 4,000 calories a day because he expends so much energy.
"I go grocery shopping three times a day, to make sure each meal is as fresh as possible. Everything Conor eats is extremely fresh and clean.
"We give the body what it needs, when it needs it. If Conor has a highly anaerobic day we give him more carbs. There are certain times he needs more fat or more carbs, and we give it to him. Everything we do is geared towards performance.
"Conor stays in shape all year around. He's super disciplined and does everything that he's told."
"There's no cheat meals. If you're driving a Lamborghini you only put top-rated fuel into that car."
The weight cut
"We do a slow, steady drop so he doesn't lose any muscle," said George Lockhart. "With boxing we don't want a big weight cut because size doesn't have too much of an impact. In MMA, with the wrestling and grappling, size plays a bigger role so our weight cut is bigger."
