Why You Should NOT Trust Fitness & Health Influencers — or Most “Personal Trainers” — With Your Body

If you are over 40 and getting health or fitness advice from TikTok, Instagram, or Facebook, you are gambling with your body.
That is not hyperbole. That is reality.
What you are seeing online is not health education. It is entertainment monetized through misinformation — and it is actively injuring people.
The Uncomfortable Truth: Most Fitness Influencers Are Unqualified and Dangerous
Let’s start with facts.
Most Influencers:
Have no degree in exercise science, physiology, nutrition, or medicine
Have never studied anatomy, biomechanics, pathology, or pharmacology
Have no clinical training with injuries, aging, or chronic disease
Are paid to push supplements, programs, and products
Looking “in shape” does not qualify someone to advise you on:
joint health
spine safety
cardiovascular risk
metabolic disease
hormone function
injury prevention
aging physiology
Abs do not equal education.
The Data:
Health Misinformation Online Is Rampant
Multiple peer-reviewed analyses of social media health content show:
20–50% of health-related videos on short-form platforms contain false, misleading, or unsupported claims
The majority of misleading content is produced by non-credentialed influencers
Engagement is highest for the least accurate content
Why? Because algorithms reward confidence and controversy, not correctness.
The most reckless advice spreads the fastest.
This Isn’t Just “Bad Advice" It’s Causing Real Harm
1. Supplements Pushed by Influencers Are Sending People to the Emergency room
Large-scale medical data shows:
~23,000 emergency department visits per year in the U.S. are linked to dietary supplements
Thousands of these cases result in hospitalization
The most common causes:
“fat burners”
energy products
testosterone boosters
detoxes
These are the exact products influencers promote daily.
They rarely mention:
drug interactions
cardiovascular strain
blood pressure spikes
arrhythmias
Because warning you doesn’t sell products.
2. “Natural” Does NOT Mean Safe
There are hundreds of documented cases of serious liver injury — including liver failure — linked to:
concentrated herbal extracts
green tea extracts
multi-ingredient “metabolic” supplements
Your liver does not care if something is “plant-based.” It cares about dose, toxicity, and metabolism — concepts influencers do not understand.
3. People's Bodies Are Getting Destroyed by Influencer-driven Training
Influencer workouts are typically:
high impact
high volume
poorly progressed
spine-hostile
fatigue-driven
They ignore:
disc degeneration
osteoarthritis
tendon aging
recovery capacity
prior injuries
medication effects
The result?
chronic back pain
disc herniations
shoulder tears
knee degeneration
overuse injuries
people quitting exercise entirely
That’s not motivation. That’s malpractice without accountability.
Now Let’s Talk About “Personal Trainers” — This Is Where It Gets Worse
Personal training is largely unregulated.
There is no universal licensing, no standardized education requirement, and no clinical oversight.
Many so-called “personal trainers”:
complete online certifications in days or weeks
pass open-book or non-proctored exams
receive no hands-on clinical training
are taught how to sell sessions, not manage risk
Some certifications require less education than a CPR course.
And yet these individuals are working with:
people with disc herniations
clients with heart disease
older adults with osteoporosis
people on blood pressure or diabetes medications
This is not just irresponsible — it is dangerous.
The Most Dangerous Myth:
“If They’re Fit, They Must Know What They’re Doing”
This belief is destroying people.
Being fit means:
good genetics
personal tolerance
youth
time to train
favorable recovery
It does NOT mean:
understanding pathology
recognizing contraindications
knowing when not to train
understanding long-term joint preservation
managing pain and injury risk
Someone can be "buff" and still have no idea how to keep YOU safe.
Why You Should Trust Me
I am not an influencer. I am not a weekend-certified trainer.
I am a PhD in Exercise Physiology and a clinical exercise professional.
That means:
I understand how aging changes your physiology
I know what exercises harm spines, joints, and nerves
I know how medications affect exercise response
I know how to train around injuries — not through them
I know when exercise is helping vs harming
I am trained to reduce risk, not chase trends
My credibility comes from education, evidence, and accountability, not aesthetics or algorithms.
If You’re Over 40, This Is Non-Negotiable
Your body is not a test subject. Your health is not a marketing funnel.
If someone:
sells "cure-all" supplements
avoids credentials
speaks in absolutes
ignores risks
promises fast results
never says “this depends”
They are not looking out for you.
The Bottom Line
(Read This Twice)
Fitness influencers and underqualified trainers are:
spreading misinformation
normalizing unsafe practices
profiting from ignorance
causing preventable injuries
If you are serious about staying strong, pain-free, and functional for life, you need education, not hype.
That’s what I provide.
