"We're on the second phase of [shoulder rehabilitation], we've worked on mobility for the past 3-4 months.
"Now the past couple of months is trying to strengthen the shoulder."
Andrews' personal story is straight out of a Rocky film.
Raised in Lower Hutt, he grew up in a home environment of drugs and alcohol abuse and was bullied in his school years, finishing without gaining any qualifications.
Moving to Australia in 2003, he discovered MMA at the Lion's Den Academy in Sydney and two years later had his first professional fight.
He spent eight years training and competing while still working fulltime.
During that time he was turned down twice for appearing on the UFC's Ultimate Fighter reality television show which known for discovering unknown fighters and making them stars.
Finally being accepted to appear on the 17th edition of the show, Andrews was not regarded as a top prospect, but won three straight fights to make the semifinals, despite an injured shoulder and cracked ribs, before being defeated by eventual runnerup Uriah Hall.
Andrews still received a UFC contract and won his first two fights before the defeat to Hester.
"It's been a long road, it hasn't been easy. The people close to me, they know the work's that been put in," he said.
Therefore, coming back to his homeland and signing posters with his own picture, Andrews is sure not to let the increased exposure go to his head.
"It's nice to go home, it's just really humbling, man.
"The fame, it just shows more of a progression, I don't think my status is better than anyone else.
"It just means what I'm doing is working."
What he accomplished just came from self belief, which was going to be the advice he offered the fighters attending his seminar at Fight Fit Gym yesterday evening. "I'm going to see all the faces that used to be me.
"It's very hard to tell someone 'you can do it', if you haven't essentially done it [yourself]. To have someone stand in front of you that has struggled and he's done it, that makes a difference.
"Belief the words don't seem like much, but they register in my head."
