Current holder of the Kickzone Semi-pro Under 93 kg light heavyweight belt, 27-year-old Holborn trains twice a day, six times a week during six intensive weeks on the run up to a fight.
This despite his last contest lasting only 38 seconds!
Liam said: "I caught the boy in a guillotine choke. He was a boxer who had moved up from middleweight - his hand speed was unreal. I tried a few kicks to the head but his footwork was too good.
"But I got him in a clinch and a standing guillotine by tightening my legs and my arms around him.
"It may be an old phrase but 'train hard, fight easy' is so true. All the bloody noses and training is worth it, even if six weeks' training ends in a 38 second fight!"
Liam certainly trains hard. And that is when he isn't in his six week preparation for a fight.
His typical timetable is thus: Mondays see him do basic weights at 6am in Berwick's FX Gym followed by sparring at night; Tuesday sees a 'light' run and 200 press ups and sit ups in the morning with hill sprints, heavy bagwork and combinations.
Wednesdays include another light run and then Liam visits his gym in Edinburgh for sparring and wrestling work.
Two hundred sit ups and push ups start off Liam's Thursday, and then a trip to his club, Alba Dornadair, who hold training in Edinburgh. He and other clubmates are put through punishing exercises by ex-paratrooper Willie Scott. Submission wrestling is also practiced, along with judo and Jiu Jitsu.
Fridays once again see weights at 6am, followed by circuit training and sparring at a high intensity.
Saturday is a day of rest before Sunday sees more sparring and an intense aquatics session in Eyemouth swimming pool with centre manager and east coast track club coach, Henry Gray, which Liam describes as 'hellish'.
And then it all starts again at 6am on Monday. The training might sound extreme, but Liam believes the regime - especially the aquatics - has helped his progress in cage fighting.
"I fought in February and actually felt better in the second round than in the first. That was all to do with Henry's training - my stamina has gone through the roof.
"Willie Scott has been involved in cage fighting for 25 years and he takes you for the last few weeks before a fight. It is torture the half hour we do with him before sparring and he uses SAS techniques such as push ups held for a minute.
"I have seen guys come along for the first time because they are interested and have been crippled by the training."
Liam started cage fighting, or mixed martial arts as it is known by competitors, four years ago after learning kickboxing while working in Lincoln.
He also took part in Thai Boxing with the Bath Dragons before he returned to Berwick and was introduced to mixed martial arts by Duns' John Wilson, of Borders Martial Arts.
He then moved on to work with his current instructor, Willie Scott, of Mixed Martial Arts club Alba Dornadair, Gaelic for Scots fighter.
Since his first fight in June 2007 which Liam lost to a submission - cage fighting's version of 'throwing the towel in' - the Berwicker has gone on to win four straight fights, all within two minutes and via submissions.
"During my first fight, I was caught in a choke.
"I was in a position I wasn't getting out of so I submitted before I passed out. Some of the moves to achieve a submission include arm locks and spine locks, which are evil."
Liam eventually aims to move onto professional fighting, where the money is slightly better, but the competition is a lot fiercer.
But fear before a fight, which can easily result in serious pain or possibly injury, is used by Liam as motivation.
He said: "I am looking to fight my next few semi-pro then go pro - the opponents are more dedicated, although you don't get paid much more. I want a few more semi-pro because I am still learning.
"Everyone has fear - it is what you do with that fear; whether you shall be a coward or a hero.
"Before a fight I focus on how much training I have done to prepare for the fight.
"It is certainly a case of mind over matter."
Liam's next fight is scheduled for October, although he has not yet been 'matched up' with an opponent.
Lack of future opponents is probably no surprise - judging by Liam's training methods and fight record thus far, it is unlikely potential competitors will be queuing outside the cage door to take him on.
