Now, there's a reason for the bizarre clip - the 6 foot 8-inch fighter, dubbed the 'Scariest Man on the Planet', is set to fight Sajad Gharibi, aka the Iranian Hulk, in London next year.
With the hype train well underway, Ford decided to respond to his opponent, who recently posted a video showing how he was getting ready for the boxing match.
Gharibi demonstrated his bizarre workout regime, which saw him punch concrete walls, rip apart melons, bend metal and slam tyres with a sledgehammer.
Captioning his post, the 29-year-old said: "YES THIS IS PERSONAL... Iranian Hulk never stops. See you April 2nd @martynfordofficial."
In a separate clip, the Iranian Hulk also showed himself punching through a gigantic bone.
Ford's response video is no doubt going to get Gharibi's blood boiling, as he appeared to mock the bodybuilder by bopping along to Eye of the Tiger.
A shirtless Ford then brought his hands up to the camera to reveal a cucumber of all things, which he pretended to strenuously bend before snapping it in two.
The UK actor and bodybuilder captioned the post: "I figured... I would take my training up a notch, and show this Hulk guy I'm not playing... so here we have it, the CUCUMBER show of strength."
As well as a series of clown emojis, he wrote: "@boxstaruk asked me to leak some training footage ... so here it is."
People on Instagram certainly saw the funny side, with one taking to the comments section to joke: "This is a powerful show of force."
"The Hulk is not going to handle such power!!!" said a second, while a third chimed in: "Need to throw a few half ass'd wall punches in mate, just for creativity of course."
The 39-year-old shared a more serious response video last week of him training with a sparring partner, who just unloads a barrage of punches to the MMA fighter's stomach.
He wrote alongside the video: "I absolutely love this S**T... we don't punch walls, we smash STEEL @boxfitcoaching We making a F**king machine... I promise you that."
Getting punched repeatedly in the stomach is a common training practice in boxing as it teaches the fighter how to effectively lessen the brunt of the blow as well as ensure they don't become winded.
It also helps them build resistance to brutal punches and it looks like Martyn can certainly take a beating.
Ultimately, he didn't seem impressed by all the things Gharibi is able to do out of the ring because, at the end of the day, it's how you fight that matters.
He said on social media: "While he's bending spanners, punching walls, cutting bones and chewing crayons ... I will put myself through the most vigorous fight camp EVER ... I will PROVE to a lot of people what I'm about that night."
Considering these two individuals are absolutely massive in their own right, there's no doubt this fight will be one for the history books.
The match will take place at The O2 in London and you can find out more about the event here.
