MARK Labbett flaunted his vigorous work-out regime on Instagram.
The beloved chaser, nicknamed The Beast for his surname and towering stature, was praised by his glam presenter girlfriend Hayley on social media for his hard work.
Hayley Palmer, a presenter for GB News, took to her stories to gush over Mark's dedication to his fitness, Mark then shared the clip of him working out to his 45.9K followers.
In the video, Mark could be seen racking up some serious steps on a stair machine, whilst in the gym.

Alongside the clips, Hayley praised: "I'm so proud of @markthebeatlabbett. He started to come to the gym with me in the mornings and he is doing so well.
"He is down to 124 kilos/ 19.5 stone. We're planning to tone and improving conditioning."
In a James Bond themed photoshoot with The Sun back in November, Oxford maths graduate confessed that he feels fortunate to have Hayley, exclaiming: “I mean, look at her.
“I keep finding myself going, ‘Hang on, we’re actually going out?’.
“I don’t want to make her blush, but 15 years ago I was a maths teacher, I was 29st.
“I’m a very, very lucky man. I’ve got the job I was born to do and, in Hayley, someone to share it all with.”
In the interview, Mark also shared his love for the gym.
He said: “My lungs appreciate it.
“I’ve lost eight inches off my chest.
“Hayley is getting me to the gym. I love weights.”
I’m a fitness pro & everyone makes the same mistake when trying to lose weight
Mark sparked concern last week after stating that he keeps an eye on presenter, Bradley Walsh
The quiz genius admitted that he and his fellow Chasers like to "keep an eye" on Bradley - so he doesn't overdo it, due to his work ethic.
Mark had previously talked about the gruelling The Chase filming schedule they all endure, which can often be recording up to 200 episodes per year.
