A few years later, Martyn launched a YouTube channel where he demonstrated resistance training exercises and workout routines. Thanks to his charisma and aesthetic physique, he quickly gained subscribers.
Fast forward to today, and Bradley Martyn is a massive celebrity in the fitness industry with over 3 million YouTube subscribers and more than 4 million Instagram followers. And he’s most well known for his bold antics and athletic feats of strength.

Bradley Martyn FAQ
Now you know Bradley Martyn’s height, weight, and body measurements. But you might want to know a little more about this bodybuilder. So here are some quick answers to other common queries.
How old is Bradley Martyn?
Bradley Martyn was born on May 22, 1989, in the San Fransisco Bay area of California. That means he turned 35 in 2024.
You may also be interested to know that Bradley Martyn was around 25 years old when his physique reached its current size, and his popularity began to grow.
How did Bradley Martyn get so big?
Bradley Martyn began resistance training when he was relatively young at just 15 years old. Therefore, he has had nearly two decades to build up his muscle size and strength.
In addition, Bradley has excellent genetics for overall muscle size and aesthetics. We can see this by looking at photos of him when he had only been training for a few years.
However, at some point in his early 20s, Martyn gained a significant amount of size in a relatively short amount of time. This fact points to the possibility that he used performance-enhancing drugs to take his physique to the next level.
What is Bradley Martyn’s max bench?
In a 2019 video, Bradley Martyn bench-pressed 405 lbs for 5 reps. So his estimated bench press one rep max (1RM) is 455 lbs.
Assuming he weighed around 250 lbs, that max bench is 1.62 times his body weight. And this lift puts him at an elite strength level compared to other men his size and age.
Is Bradley Martyn on steroids?
Like most fitness influencers, Bradley Martyn doesn’t discuss whether he uses performance-enhancing drugs because that could take away from his following and product sales. However, he has made Instagram posts claiming to be a “lifetime natural,” possibly jokingly.
Regardless, we can predict Bradley Martyn’s steroid use based on his overall physical development and any noticeable side effects.
Martyn’s skin appears reddish and flushed, with small bumps around his chest and neck. Also, his hairline began receding at a young age, although this could be hereditary.
As for his physique, Martyn has a tremendous amount of mass and typically has a body fat percentage somewhere around 7-8%. Even when bulking up, he rarely exceeds 10% body fat.
Finally, Martyn has elite-level strength compared to other men in his weight class. His videos often show him performing inhuman feats of strength with crazy athleticism for someone his size. But does that prove he’s not natty?
For a more quantifiable approach, Bradley Martyn’s fat-free mass index (FFMI) score is 28.5. The average man has an FFMI of 19.5, and 25 is considered the natural limit. So an FFMI above 28 is most assuredly indicative of steroid use.
While Bradley Martyn may have been natural early in his career, I think he has been on steroids since sometime in his early 20s.
What’s up with Bradley Martyn’s hair?
You’ve probably noticed that Bradley Martyn wears a hat in pretty much every photo and video. So it’s only natural to wonder what he’s hiding under that lid!
It turns out the reason Bradley Martyn always wears a hat is that he’s extremely self-conscious about his receding hairline. And this is something he’s been struggling with since he first noticed his hair thinning at around 23 years old.
In the video below, Martyn opens up about his insecurity while getting a haircut at his gym. This was a big step in Bradley’s hair journey, he continues wearing a hat in most of his pictures and videos.
More recently, Bradley Martyn has undergone hair regrowth procedures to restore his hairline. One video shows Martyn getting platelet-rich plasma (PRP) injections, although this may not be the only method he used.
It’s also speculated that Martyn underwent a hair transplant, given the significant regrowth. And that the PRP was a decoy to distract from the transplant while making money selling a drug protocol.
