It happened. The crossover nobody—or maybe everyone—was waiting for.
When the video dropped of David Goggins putting Israel Adesanya through a workout that looked more like a sanctioned torture session, the internet did what it does best. It melted down. You had the hardcore Goggins fans screaming about "taking souls," while the MMA purists were busy face-palming, worried that Izzy was going to blow out a knee or fry his central nervous system before his next walkout.
But if you actually look at what happened in that gym, it wasn't really about the calories burned.
Honestly, it wasn't even about the cardio. It was a weird, intense psychological experiment between two men who have already conquered their respective worlds but are currently standing at very different crossroads.
Why David Goggins and Israel Adesanya Linked Up Now
Let's look at the timing. It's everything.
Israel Adesanya, "The Last Stylebender," isn't just another fighter. He's a guy who defended the middleweight belt so many times he basically ran out of people to beat. Then came the stumble. Losing the title, the weird loss to Sean Strickland, and then a defeat to Nassourdine Imavov. For the first time in his career, the "main character" energy felt a little bit... dampened.
When an elite athlete feels like they've lost their edge, they don't go to a life coach. They go to a monster.

And Goggins? He’s the ultimate monster. The retired Navy SEAL has carved out a niche as the guy you call when you want to see if you still have "it." He’s not a technical striking coach. He’s not going to help Izzy check a leg kick. He is there to find the part of your brain that wants to quit and yell at it until it shuts up.
The Workout That Broke the Internet (and Izzy)
The footage was raw. It wasn't one of those polished Nike commercials with high-contrast lighting and inspirational music. It was just a 50-year-old man who doesn't seem to produce lactic acid absolutely dogging one of the greatest fighters to ever live.
Here is the reality of what they did:
- A 5-mile "warm-up" run: They weren't jogging. They were hitting a roughly 7:40 pace. For a pro fighter, that’s manageable. For a 50-year-old with "Goggins knees," it's a statement.
- The AirBike from Hell: Goggins was seen barking "60" and "70" at Izzy. For those who haven't used an Echo bike or an Assault bike, those numbers refer to RPMs. Maintaining 70 RPMs when you’re already gassed feels like your lungs are being filled with hot sand.
- The Stairmaster Collapse: This was the clip that went viral. Adesanya literally fell off the machine. He was done. Physically, the tank was empty.
But Goggins didn't help him up with a "good job, champ." He stayed in his ear. "Get it back on! Get it back on!" It sounds harsh. Kinda is. But that's the whole point of the Goggins methodology. He wanted to catch Izzy at the exact moment of failure to see how he'd react.
The "Stay Hard" vs. Sports Science Debate
There’s a lot of noise from MMA coaches about this. And they have a point.
Training like David Goggins is, scientifically speaking, terrible for a fight camp. It’s high-impact, it’s catabolic, and it puts immense strain on the joints. If you're three weeks out from a five-round war in the Octagon, you should be tapering and focusing on fast-twitch explosive movements, not running 10 miles until you puke in a bin.

But Izzy isn't an amateur. He knows his body. This wasn't about physical conditioning; it was about mental callousing.
What Really Happened in That Room
If you listen to the audio from their post-workout chat, it gets surprisingly deep. Goggins wasn't just there to be a drill sergeant. He was talking about "the tightrope."
He explained to Adesanya that most people let their minds drift when things get hard. They think about the championship they already won or the money in the bank to justify quitting. Goggins’ goal was to shorten that "drift time."
"When your world ends, mine begins."
That’s a classic Goggins-ism, but it actually means something in the context of a fight. When a fighter is in the fourth round, bleeding, tired, and looking at the clock—that’s when the world ends. If you’ve spent your camp "visiting" that dark place with a guy like Goggins, you don't panic when you arrive there on Saturday night.
The Strickland Factor
There is a sub-plot here that makes this even tastier. Sean Strickland, the man who arguably started Izzy’s recent "slump," has his own history with Goggins. Strickland famously trolled Goggins online, calling his training "nonsense" and challenging him to a sparring match.

By training with Goggins, Adesanya is basically doing a "get-back." He’s adopting the very mindset that his rivals mocked.
Adesanya told Goggins, "I already told my coach... it's time. I know who I wanna fight." He’s gunning for a rematch with Strickland. He wants to prove that the version of him that lost wasn't the "real" him. He’s looking for that "rebirth" that Goggins supposedly gave Tony Ferguson—though, to be fair, Ferguson's post-Goggins results have been a mixed bag.
Is This Actually Good for Izzy’s Career?
Look, we have to be honest. Goggins is 1-0 against UFC champions' gas tanks, but he’s 0-2 in terms of actual Octagon results for the people he trains.
- Tony Ferguson: Went through "Hell Week" and then looked stiff and slow in his subsequent fights.
- Jon Jones: Goggins was in his camp for the Gane fight. Jones won in minutes, so Goggins' endurance training didn't even get tested.
The risk for Adesanya is the "Goggins Hangover." You can’t just redline your engine every day and expect it to purr when it's time to race. However, Izzy’s game has always been 90% mental. He’s a "vibe" fighter. If he feels like a monster because he survived David Goggins, he fights like a monster.
Actionable Takeaways from the Goggins-Adesanya Session
You don't have to be a UFC champion or a Navy SEAL to use what happened in that workout. If you're looking to level up your own discipline, here's the "non-pro" version of the Goggins/Adesanya playbook:
- Find your "drift" point: Next time you’re working out or even doing a boring task, notice when your brain starts making excuses. "I've done enough." "I'll do more tomorrow." That's the drift. Bring it back to the "breath" immediately.
- Vary your intensity, but keep the discipline: You don't need to puke in a bin. You do need to do something that sucks every day. If you hate the cold, take a 30-second cold shower. It’s about the "negotiation" with your inner bitch.
- Don't ignore the science: If you’re training for a specific goal (like a marathon or a tournament), don't let "mental toughness" override your recovery. Goggins is an outlier. Most humans need sleep and foam rolling.
- Watch the eyes: Goggins mentioned he "sees the eyes" in Adesanya. When you're pursuing a goal, check in with yourself. Are you just going through the motions, or are you actually "locked in"?
Ultimately, the David Goggins and Israel Adesanya collaboration is a reminder that even at the highest level of sport, the biggest battle is the one happening between your ears. Whether this leads to another gold belt around Izzy's waist remains to be seen, but one thing is for sure: he isn't going to be the one who quits first in the fifth round.
The Last Stylebender might just be getting his mojo back, one Stairmaster session at a time.
