Evan Seinfeld has been screaming on stage for decades.
He fronts Biohazard, the New York hardcore band that helped invent the sound.
Then he went and did something even louder. He built a fitness crew for metalheads.
I sat down with him right after leg day, which I crushed to Biohazard (his band).
Here’s what he told me.
“I was 60 pounds overweight on stage”
Evan didn’t always look like this.
He remembers doing the same songs, on the same stage, carrying about 60 extra pounds.
“It was hard,” he said.
And here’s the weird part: he didn’t even know how hard it was.
It was just his body.
The funny thing is, he was always working out. He just didn’t know how to eat.
He’s open about this, so I’ll be too: he had a lot of food issues. He was a chubby kid.
He was anorexic at 14.
He’s dealt with body dysmorphia, and he says he still wrestles with it sometimes.
His fix? “Get in shape now.”
He says he still catches himself in the mirror and thinks, “Not a fat kid anymore, are you?”
He’s 74.6 kilos now (about 164 pounds). He’s not a giant.
He’s lean and strong, and he says he built that with his own hands.
“I wasn’t born like this. I did this. This is my work.”
Keep reading. The workout he does is not what you think.
What his day really looks like
Evan lives between Tulum, Bali, and Italy.
His days are built around training.
Work gets scheduled around his workouts, not the other way around.
- Morning: Gym for about an hour, plus 15 minutes of abs and stretching. “The Gym is my temple.”
- Right after: Food. Always.
- 2–3 days a week: Muay Thai, one hour, private lessons. He says he sweats more there than in the sauna.
- Afternoon: A light snack, like coconut yogurt and fruit, so he’s not stuffed for yoga.
- Evening: Yoga at home with his girlfriend. A private teacher, 20 years of experience, and it costs less than one class in an American city.
- Night: Sauna at 9.
And every single day, no matter what: 100 push-ups.
He does his push-ups while he talks to people.
He does them in airports.
He lays down a yoga towel, takes off his jacket and shoes, and goes. “I don’t have to drink a sugary Starbucks and walk around buying things I don’t need.”
The eating rule.
Evan is vegetarian (for the animals). No red meat, no chicken, nothing.
His breakfast is almost always rice and eggs.
Same thing, every day. “Eat like a dog” is a rule in his program.
Eat the same simple stuff and stop overthinking it.
He counts his macros.
When your dream body is Brad Pitt in Fight Club, he says, you have to get under 10% body fat, and nobody gets there eating a bunch of bread.
His guilty pleasure is cheese.
He grew up in Brooklyn, so he loves pizza.
But you won’t see him eat the crust 🍕
The trick that turns workouts into a superpower
Here’s the part I loved.
Evan works out to full albums.
He picks one record and trains to it all week. Then he switches the next week.
Recent picks: Black Sabbath’s Mob Rules, Metallica’s Kill ’Em All, and Quicksand’s Slip.
Why does it work?
When you move on the beat, he says, the music takes you back to being an angry teenager.
You feel 21 again. He goes into a trance.
And when his headphones die? “All bets are off.”
(He told me he once begged the front desk for a charger because he’d already taken his pre-workout. Relatable!)
His own tour playlists go from Celtic Frost to Madball, and about a third is old Sabbath and old Metallica.
He also thinks most gyms get this wrong.
They play Bruno Mars to please everyone.
And most workout plans try to please everyone too.
Evan wants to please just one group: his crew.
Full Metal Fitness: a gym for people who aren’t “gym people”
So Evan built his own.
Full Metal Fitness is an online fitness crew for metal and hardcore fans. Guys in their 40s and 50s are getting ripped, dropping 50 pounds, and finding friends in the process.
Here’s what you get when you join:
- A custom workout plan
- A diet plan
- A video call with Evan to start (where you are, your age, your injuries, how you eat)
- A weekly check-in call
- A playlist
- An accountability partner on day one
That last one is the secret sauce.
Your partner is another metalhead, usually around your age, usually from a different country.
If your partner lives in Dublin and you live in America, he’s up six hours before you. And he’s waking your butt up.
There’s also a WhatsApp group with about 40 guys swapping pre-workout tips, concert stories, and “name your top five bands” challenges.
The price? One dollar a day. That’s less than most gym memberships.
The results are wild.
One guy lost 30 pounds and got a huge Full Metal Fitness tattoo.
Evan doesn’t even have one yet.
Another guy is about to take his shirt off in a mosh pit for the first time in 15 years, after losing 35 pounds.
Two members are dads of four and five kids, with full-time jobs, and they still get their workouts in.
Evan says the crew is the whole point. “Everybody knows how hard it is to start again on your own.”
The 50-second push-up test
Evan also made a free 60-minute workout on his site.
It has a warm-up, the workout, and a yoga cool-down.
The push-ups are done on the beat… which I thought was really cool!
Sounds easy. It’s not.
Each move is only 50 seconds.
But when they filmed it, Evan watched guys half his age “drop like flies” during the push-ups.
Even he almost couldn’t finish.
Evan says more people tell him it’s too hard than tell him they finished it. 😂
Doing hard things is the ultimate key to building self-confidence.
Why he doesn’t care about huge muscles
Evan isn’t training to be a bodybuilder.
He’s thinking about the last 30 years of his life.
“How are you going to age? Do you want to do it in a wheelchair, hunched over?”
He wants to move around with his kids and grandkids.
He wants to travel when he finally has the time and money. “When someone loses their health, they realize it’s the only thing.”
And he’s not done learning.
His goals: nail the dragon flag this year (the “soul crusher”), and get a muscle-up and a handstand by the end of 2027.
The monkey story that made him cry
This is the moment in the interview where Evan got emotional.
He loves watching monkeys.
He once rented a house in Costa Rica full of giant monkeys. And he noticed something…
When a monkey swings from one vine to the next, there’s a split second where it’s holding on to nothing.
To get where it’s going, the monkey has to let go.
“I’m getting emotional because it’s metaphoric for my life.”
For years, Evan lived in LA, getting angrier.
He says he was depressed and anxious, and he “didn’t know how to be depressed.
I know how to be angry.”
Then his son and his best friend sat him down like an intervention.
His son said he was “like Larry David on TRT.” Evan laughed.
Then he felt seen.
He moved to Mexico the day after the funeral of a close friend. “One of my friends’ lives ended and my life started over.”
What he tells guys who feel stuck
Evan has run a men’s community for five years and says he’s listened to about 5,000 men.
His advice is simple:
- Go to the gym.
- Do yoga.
- Do 10 minutes of breathwork every morning.
- Tear the building down. Don’t keep repainting the old one.
He says most men stay in a bad situation for life because they don’t believe in themselves enough to try something new.
And his favorite line from the whole interview?
“The worst one is ‘I could never do that.’ Who told you that? If you could never do that, you never will.”
Evan’s tour rules
His three non-negotiables on the road: the gym when he can, push-ups and a yoga flow before the show, and clean eating.
He stashes simple whole foods on the band rider, because most venues give bands “disgusting” food.
For recovery, he’s a sauna junkie. “If I don’t get in the sauna for a couple of days, I get like the Tin Man. I need oil.”
On rest days he takes a long, slow walk on the beach, no rushing.
The stage routine is the funniest part.
He drinks green tea with Throat Coat and honey.
He takes only a few sips of water on stage.
And he sticks two caffeine pouches under his lip. So if his top lip looks weird in the photos, now you know. 😅
The big takeaway
Evan’s whole message comes down to this: fitness is the cheapest therapy you can buy, and it works better with your people.
He told me to go to the gym every day and train until your heart is pounding. And remember, you’ve got one body.

Biohazard is also heading out on tour in 2027, starting in South America in February, then Asia and the South Pacific, and Europe’s festivals in August and September.
And yes, he plans to come to Portugal.
I’ll be there!
