“Try not to tear a f***ing pec off the bone,” laughs Tristan Barnes as he slides onto the bench. Seconds later, that ill-fated joke came true.
The 23-year-old bodybuilder — a coach and online content creator from Manchester — was midway through what he called a “regular gym session with the boys” when a routine lift went catastrophically wrong.
Moments after joking about the very thing, he felt his chest explode in pain.
“Ah! F***,” he yells. “I just tore my pec! I’m not even f***ing joking.”
In a YouTube video explaining exactly what happened and how it has impacted his training, Tristan said: “It wasn’t during prep. It wasn’t an ego lift. It wasn’t some high-stakes program or maxing out week. It was just a regular gym session with the boys. And we were having a laugh, training, filming a bit, and moving through a normal day.”
He also revealed that he’d only recently decided to reintroduce bench pressing into his workouts for fun. “The week before, we decided to bring bench pressing back in,” he told viewers. “I hadn’t benched properly in a while. Dumbbells and machines had been my go-to for months, but we thought it’d be fun. Nothing serious.”
The warm-up went fine, as he describes: “I started warming up. Felt pretty good. 100kg moved smoothly, and there were no issues. Then I jumped to 140.”
That’s when the red flags started appearing. “Things started feeling a bit off. It didn’t feel bad enough to stop, but it didn’t feel great. Then mid-session, I was actually holding my chest. I didn’t think much of it at the time, but now that was my body telling me something was about to go wrong,” he reveals.
He went ahead with the set anyway — and everything fell apart on the third rep.
“A loud pop and an instant loss of strength. Mid-rep, right in the center of my pec. Luckily, Sam was there to take the bar off me,” Tristan recalls. “The second it happened, I just froze. All I can remember was this sharp stabbing pain across my chest, and I couldn’t move. I didn’t need anyone to tell me what it was. I just knew.”
The footage — later shared online — shows him swearing and clutching his chest as his arm gives way, the weight clattering to the floor.
But that was just the start of a months-long ordeal.
After the injury, he went to hospital. “Chest was tight, couldn’t move properly, and I knew there was something seriously wrong” he says. “I walked into A&E and they told me it would be an 8-hour wait.”
So he went home. But that night, everything turned purple, as he tells viewers: “I looked in the mirror and my entire pec had turned purple — like a deep, bruised mess.”
A scan confirmed the worst: a full rupture, with his pec “11cm away from where it was meant to be.”
Surgery followed two weeks later – but the injury had already started to take its toll, mentally. “Waiting with a detached pec, not being able to train, not being able to recover — that broke me mentally,” Tristan says.
He tried to get back to normal, but then he was dealt another blow.
“Two weeks after the surgery, I had a Vanquish event and everything seemed fine,” he recalls. “I was coaching, catching up with people, filming, and training with my client Joe. But straight after our session, I felt off, like my body couldn’t regulate its temperature. One second, I was sweating buckets. The next, I was shivering cold.”
The next day, things got even worse. “I started having intense stomach cramps. It felt like my core wouldn’t relax. Stomach was churning, like something inside was off. Then that night, I woke up in a wet patch. Not sweat, but pus. My surgery site had started leaking.”
It turned out the wound had become infected, as he says: “I even had tissue hanging from the wound.”
He spent a week in hospital fighting infection and was told he’d come within minutes of sepsis. “Eventually, the surgeon came in and told me the worst. The stitches had gotten infected, traveled down the initial surgery site, and that they were going to have to go back in. He said that he might have to undo the entire original pec reattachment.”
Barnes underwent a second surgery but woke up to good news. “He said that the tissue had healed better than expected,” he says. “And honestly, I believe it’s down to the BPC-157 and the TB-500 and growth hormone that I was using after the first surgery. They all sped up the recovery and it bought me a second chance.”
Still, recovery has been brutal. “Right now, I’m two weeks post-second surgery, and the stitches have been removed. Movement is minimal, and I’ve lost around 15 to 20 kg of muscle. My body feels completely foreign.”
He’s been open about how much the ordeal has affected him mentally. “Mentally, it’s the worst I’ve ever been. I’ve built my identity around building muscle, progressing, and being strong. And now I can’t even open up a door with my left arm.”
But instead of disappearing, he turned the setback into content — and a message. “So, I made the decision to document everything. I posted as much as I could and spoke about it every single day. I poured my focus into my online coaching clients. And weirdly enough, it started paying off. I actually made £1,800 from TikTok videos alone.”
Eight weeks after the injury, he wrote on TikTok: “8 weeks since tearing my pec. 2 surgeries. A brutal infection. 20kg of muscle lost. Confidence shattered.”
Now, though, he’s rebuilding — both physically and mentally.
He says that embracing more of a social media presence has been “the only light in what’s honestly been the darkest tunnel I’ve ever been through before”.
“So yeah, I get it. To some people, it might seem like the pec tear is all I talk about. But if you were in my position, what would you do? This is how I cope,” he explains. “This injury doesn’t define me. What defines me is how I respond. I’ve been knocked down. I’ve had two surgeries. I’ve watched my size, my strength, my intensity get stripped away.
“But I am not done. I’m still here, and this is just the beginning of the rebuild.”
And for anyone else struggling — whether through injury or anything else — Barnes’ final message is simple:
“If you’re watching this and you’re dealing with something tough — an injury, a setback, or just feeling stuck — know that you’re not alone. There will always be a way back. So, stick around. The comeback starts now.”
Tristan has since continued to create content for social media, now boasting an impressive 75,000 followers on TikTok, where he shares his candid advice for fitness lovers.
