That means ditching the jagerbombs, bulking up muscle and putting himself on a super strict diet before heading into the cage. Eek!
MMA sees its fighters take on a number of combat sports including judo, jiu jitsu, Muay Thai and kickboxing - and some of its UFC stars have gone on to become global sensations. Everyone has seen Conor McGregor and Ronda Rousey popping up in the press in the last few months, right?
Speaking to MTV recently, Aaron revealed his plans to take part in his first MMA fight and it sounds like he's got the full support of his Geordie Shore co-stars. The reality star said: "I'm not going to lie, I think the other Geordies are more excited than I am. Gaz is wanting to walk out with us! I'm like, 'It's not the UFC Gary, it's just a venue in Liverpool!' Now the fight's booked in, the plan is to stick to a strict diet and put on as much muscle as possible. It's pretty strict."
That's not exactly easy to do when your job is to go out and party every night for up to six weeks at a time. Admitting his latest stint in the Geordie Shore house (where he joined old and new castmates to film the show's five year special) put a setback in his plans, Aaron added: "I'm not gonna lie, because we've just filmed Geordie Shore I have been drinking but not since we've been out of the house and I don't plan on drinking any time soon because I want to get in fighting shape."
He's certainly been trying!
Fans of Aaron will now that he has been training hard and has even ventured to Thailand to brush up on his fighting skills, but that hasn't stopped him from admitting he is a little "nervous" as well as excited about his MMA debut.
If all goes well, Aaron has revealed he would like to pursue the sport professionally - not until Geordie Shore is all over, that is. Phew!
He is set to make his return to our screens next week when Geordie Shore's twelfth series airs on MTV. The cast have teased things get pretty explosive this time round (doesn't it always?) and from the get go, Aaron is cheekily trying to wind up Scotty T.
How you ask? He's making a beeline for Chloe. Yup, he and Gaz decided to prove that Scott is bothered about Chloe deep down, after she confessed her feelings for him, and to do so, Aaron turns on the charm.
The show will also see the return of Marnie Simpson (now she is a single lady again) and Marnie has teased she and Aaron pick up their on/off romance once more...
We can't wait to see our faves back in action!
Geordie Shore returns Tuesday 15 March at 10pm on MTV.
