There was a time when fitness myths travelled slowly.
They passed between gym partners, floated around locker rooms, or hid in the back pages of muscle magazines. Now, they travel at the speed of a scroll — dressed up in viral hooks, affiliate links and 30-second promises.
And if there’s one man who has seen every fad come and go, it’s Arnold Schwarzenegger.
The bodybuilding icon, who moved to America in 1968 at 21 years old, built his reputation the hard way. A four-time Mr. Universe champion and seven-time Mr. Olympia champion, he later became an Emmy-award winning actor and a two-term governor of California.
Shortcuts were never part of the plan.
So when Schwarzenegger sees new TikTok trends promising dramatic results with minimal effort, he isn’t impressed.
In a recent edition of his Arnold’s Pump Club newsletter, he pointed to a survey conducted by Zing Coach, a personal trainer app, which found that 56% of 18-to-27-year-olds admit to using TikTok for fitness advice — and one in three don’t verify what they’re watching.
For Schwarzenegger, that’s a red flag.
He urges people to switch on what he calls their “shyster radio” and question what they’re being sold. “The content isn’t designed to help you. It’s designed to be interesting,” he says.
And he highlighted four trends in particular that he believes people should avoid.
Dry Scooping Pre-Workout
Pre-workout supplements are designed to be mixed with water before training. But a growing social media trend sees users pouring the powder straight into their mouths, claiming it makes it “hit faster”.
Schwarzenegger doesn’t deny something hits faster — just not in the way people hope.
“What actually hits faster is respiratory distress and a dangerously elevated heart rate from absorbing a massive dose of concentrated caffeine all at once.”
Instead of a performance boost, he warns the practice can spike heart rate and land people in the emergency room.
‘Nature’s Ozempic’
Another viral claim revolves around berberine, a plant compound found in goldenseal and barberry. On TikTok, it’s been labelled “Nature’s Ozempic”, with influencers suggesting it mirrors the effects of weight-loss medication.
Schwarzenegger isn’t buying it.
“One expert put it simply: there is zero similarity between berberine and Ozempic. But the influencers pushing it got millions of views, and a lot of them got paid by supplement companies. Funny how that works.”
Research shows users lost about four pounds on average over a few months — hardly the dramatic transformation being implied.
Ab Challenges
Six-pack-in-30-days routines have been around longer than the internet itself. The format changes, but the promise remains the same: follow this exact daily ab routine and watch your stomach transform in weeks.
Schwarzenegger’s response is blunt.
“You could do a thousand crunches a day, and it won’t remove the fat covering your abs. That only happens through your overall diet and training.”
Spot reduction, he insists, simply doesn’t exist. Visible abs come down to lowering overall body fat through consistent training and controlled nutrition — not marathon crunch sessions.
The ‘Internal Shower’
If there’s one trend that seems to irritate him most, it’s the idea of detoxing your body with specific food combinations. The latest version? Chia seeds and lemon juice in water, marketed as an “internal shower”.
Schwarzenegger isn’t having it.
“Your liver and kidneys handle detoxification. They’ve been doing it since you were born.”
He adds: “Again with the toxins. Your liver and kidneys handle detoxification. They’ve been doing it since the day you were born. Chia seeds are fine! They have fibre that you need! They’re not a shower for your insides. That’s not a thing.”
No Hacks. Just Work.
At 78, Schwarzenegger’s message hasn’t changed. There are no magic tricks. No secret powders. No viral hacks.
Instead, he returns to fundamentals — structured training, progressive overload and consistent nutrition.
“Are you getting your protein? Are you eating vegetables? Are you training on a plan instead of something random every day? Are you progressing every week, whether it’s 5 more pounds or 1 more rep? That’s it. That’s the formula that built every great physique in history, including mine. Nobody wants to hear that because it’s not exciting,” he says. “But it works. Every single time.”
He doubles down further, adding: “Programmes built around intensity and progression work, but random workouts of the day don’t. Supersetting opposing body parts makes you stronger. The hard reps, the ones where you want to quit, those are the reps that make you grow. And there isn’t a magic diet. Just a brutal equation of whether you eat less than you burn.”
And if all that sounds boring… that’s because it is. But that doesn’t mean it isn’t effective.
“I’ll say it again because this is the investment with the greatest return: The best advice in fitness is boring,” Arnie says. “Eat enough protein. Eat your vegetables and get enough fibre. Follow a real programme. Progress every week. Sleep. Be patient. No one is getting famous off that advice, but it’s the advice that actually works.”
In an era built on viral shortcuts, Schwarzenegger’s stance is refreshingly unfashionable.
Do the basics. Do them consistently. Ignore the noise. It might not trend. But it’ll keep you safe, fit, and healthy.
