Mel Gibson flashes biceps as he trains with Peaky Blinders star Patrick O'Brien

The New Yorker decided to squeeze in a workout before his Experience With Mel Gibson on Sunday night at the Doubletree Hilton Hotel.

Fans paid upwards of £100 (€117) a ticket to attend the exclusive event, and some even forked out £300 (€352) to get a picture with the actor.

But before that, Mel popped into Everyday Athlete Gym where he met the owner, Irish actor Patrick O’Brien, and trainer Tommy Young.

The 66-year-old seemed to have worked up a sweat, grinning for a photo in a damp vest and baseball cap.

Everyday Athlete Gym shared the photo on their Instagram page, writing: “It was great to have the one and only ‘Mel Gibson’ come and train @everydayathletegym today. Alba gu Bra! #melgibson #madmax #martinriggs #braveheart”

The last time Mel stepped foot in Scotland was when was attending the premiere of his 1995 film Braveheart, which was filmed in the Scottish Highlands and Ireland.

He previously revealed that the film’s crew moved production to Ireland as Scottish people were not “friendly enough.”

“We started off in Scotland and we were thinking, ‘How are we going to do this? It’s not horse-friendly. It’s not people-friendly,” he said in an interview with Today FM.

The actor added that President of Ireland Michael D. Higgins, who was Minister for Arts at the time, really helped them out.

“He opened the gates up over here for us and really greased the wheels and helped us get it done.”

And while Mel enjoyed his time on the Emerald Isle, he admitted that his busy schedule made his memory a bit foggy.

“I was getting like 4 hours a night’s sleep and working 7 days a week [so] I don’t remember a whole lot. [I have] vague memories of painting myself blue and just turning up,” he laughed.
