10 Red Flags You Shouldn’t Ignore
Let me tell you something that might sound strange coming from an online personal trainer. Not everyone needs one. And not every personal trainer deserves your money.
There. I’ve said it.
The fitness industry has a relatively low barrier to entry. Almost anyone can create an Instagram profile, post a few photographs of their abs, put “Online Fitness Coach” in their bio, and start selling training programs.
Some of those people are excellent coaches. Others are excellent photographers. And some are simply excellent salespeople.
The problem is that, from the outside, they can look remarkably similar. You are over 40 and if considering hiring an online personal trainer, the decision deserves some thought. You’re investing your money, your time, and quite possibly a fair amount of trust in someone you’ve never met.
Behind the curtain and me personally being dissapointed in the past, here are things to help you distinguish a good coach from someone who’s simply good at marketing?
“Lose 10 kilograms in 12 weeks!”
1. They Promise Specific Results Before They Know Anything About You
“Build the body of your dreams in 90 days!” “Guaranteed transformation!” You’ve probably seen these promises a thousand times. Now ask yourself something.
How can anyone guarantee your results without knowing your age, weight, training history, medical circumstances, eating habits, available time, or even what you’re trying to achieve?
They can’t.
Of course, an experienced coach can make reasonable estimates after assessing your situation. We understand how bodies generally respond to training and nutrition. But an estimate is not a guarantee.
A man who has never trained before, carries considerable excess body fat, and has plenty of time to exercise is starting from a very different position than someone who has been lifting weights for twenty years and wants to lose the last two kilograms of fat.
Their progress will not look the same.
A good coach should explain what’s realistic for you, not promise you the same results as everyone else.
2. They Sell You a Program Before Asking About Your Life
Imagine visiting a tailor. You walk through the door, and before anyone measures you, the tailor hands you a suit and says, “This will fit perfectly.” You’d probably walk straight back out. Yet that’s effectively what happens with some online fitness coaching.
You pay, answer three basic questions, and receive a workout program that looks suspiciously similar to something you could download for free.
There’s nothing inherently wrong with standardized training programs. They can work very well, especially for beginners. But there’s a difference between buying a general program and paying for personalized coaching. If someone advertises individual coaching, I would expect them to ask about your experience, goals, physical limitations, schedule, equipment, and preferences.
And not just ask. Actually use the answers.
Because a program that requires five gym sessions per week isn’t particularly useful if you can realistically manage two.
3. Their Own Body Is Their Only Qualification
This one might annoy a few people.
Having an impressive physique doesn’t automatically make someone a good personal trainer. It demonstrates that they’ve achieved something with their own body. That’s certainly worth recognizing. But it doesn’t tell you whether they can teach, communicate, assess someone else’s abilities, or design an appropriate program for a person with completely different circumstances.
A naturally lean 25-year-old who has spent six years bodybuilding may understand his own training very well. Does that automatically qualify him to coach a sedentary 55-year-old with a demanding career, limited mobility, and twenty years of unsuccessful dieting? Not necessarily.
And the reverse is also true.
A trainer doesn’t need to look like a professional bodybuilder to be knowledgeable and effective. I believe a coach should practice what they preach. But their appearance should be one piece of evidence, not the entire argument.
Ask about their education, practical experience, and the kinds of clients they work with. And listen to how they explain things. Someone who truly understands a subject should be able to discuss it without hiding behind complicated terminology.
4. Every Client Gets the Same Diet
Chicken. Rice. Broccoli. Repeat. Maybe some oats in the morning, a protein shake after training, and a handful of almonds if you’re feeling adventurous.
Congratulations. You’ve discovered approximately half the fitness industry’s nutritional imagination.
I’m exaggerating, obviously. But not by much.
Nutrition coaching should account for your preferences, habits, lifestyle, and goals. It should also respect the fact that food is more than fuel. You eat with your family. You go to restaurants. You celebrate birthdays. You travel. You enjoy particular foods because they taste good, remind you of something, or simply make you happy.
I’ve spent years working professionally with food, including running my own restaurant. I know how much pleasure a good meal can bring. And I see absolutely no reason why improving your body composition should require abandoning that pleasure. If a coach insists that you must eat from a tiny list of approved foods, I’d ask why. If they can’t explain the nutritional reasoning, or can’t accommodate ordinary preferences, I would be concerned.
A good nutrition strategy should work in your actual life. Not in an imaginary world where you never attend a dinner party.
5. They Treat Exhaustion and Pain as Proof of Progress
“No pain, no gain.” I wish this phrase would finally retire. Training needs to be challenging enough to produce adaptations. That’s true. But being completely exhausted after every session isn’t evidence of an effective program. Neither is being so sore that you struggle to sit down for three days.
Muscle soreness can occur when you introduce unfamiliar exercises or increase training demands. It isn’t a reliable measure of how much muscle you’ve built.
And pain, particularly sharp or persistent pain, shouldn’t be dismissed as weakness. This becomes especially relevant when you’re over 40 and perhaps returning to exercise after years of inactivity. You need an appropriate starting point and a sensible progression. Not someone trying to demonstrate how tough their workouts are.
I care far more about what you can sustain than what you can survive.
6. They Have a Supplement for Every Problem
- Not losing weight? Buy this fat burner.
- Not building muscle fast enough? Try this special formula.
- Feeling tired? Here’s another powder.
Before you know it, you’re spending more on supplements than on groceries.
Some supplements have legitimate uses. Creatine, for example, has substantial research supporting its role in certain strength and high-intensity exercise contexts. But most people don’t need a cupboard full of expensive products to become stronger, lose fat, or improve their general fitness. They need appropriate training, adequate nutrition, recovery, and consistency.
Be particularly cautious if your coach seems more interested in selling supplements than understanding why your progress has stalled. And if their advice comes with a discount code for everything they recommend, it’s reasonable to ask whether they’re receiving a commission. That doesn’t automatically make the recommendation wrong. But you deserve to know.
7. They Can’t Explain Why You’re Doing an Exercise
“Because it’s in the program.”
That’s not a particularly satisfying answer, is it? You don’t need a university lecture every time you ask about a squat or a rowing exercise. But your trainer should understand why a movement has been selected, what it’s intended to achieve, and how it fits into your overall program.
They should also be able to offer alternatives when necessary. If an exercise causes discomfort, isn’t suitable for your current abilities, or requires equipment you don’t have, there may be another way to train the same movement pattern or muscle group. Good coaching isn’t about defending every exercise as though it were sacred. It’s about choosing appropriate tools for the job. And sometimes changing those tools.
8. They Disappear After You’ve Paid
Before you pay, they’re incredibly attentive. They answer every message within minutes. They ask about your goals, tell you how excited they are to work together, and assure you that you’ll receive personal attention.
Then the payment goes through.
Silence. Three days later, you receive a training plan and a message saying, “Let me know if you have questions.”
Now, let’s be reasonable.
An online coach isn’t necessarily available 24 hours a day, seven days a week. They have other clients, responsibilities, and a life of their own. I certainly do. But communication expectations should be clear before you start.
- How often will your coach review your progress?
- How can you contact them?
- When should you expect a response?
- What happens if you’re struggling with an exercise or need an adjustment?
Different coaching services offer different levels of support. That’s perfectly acceptable. What’s not acceptable is selling intensive personal coaching and then delivering almost no personal attention.
9. Their Testimonials Look Too Good to Be True
Before-and-after photographs can be useful. So can client testimonials. But they need context. A photograph doesn’t tell you how long the transformation took, what the person did, whether the lighting changed, or whether the results are representative.
And a testimonial doesn’t automatically prove that the coach’s methods caused the outcome. If every client supposedly loses enormous amounts of fat, builds visible muscle, doubles their energy, and completely transforms their life in twelve weeks, I’d become suspicious.
Not because impressive results are impossible. But because real people are different. Some progress quickly. Some slowly. Some encounter setbacks. Some discover that their original goals weren’t particularly realistic. That’s normal.
I would much rather read a believable account of someone’s actual experience than a collection of miraculous transformations. And yes, it’s perfectly reasonable to ask whether testimonials come from real clients. Trust should be earned, not manufactured.
One thing you should also know about me – I never post photos of my clients. Yes, we use progress photos to measure progress and evaluate, but they remain in our private space in the app.
10. They Make You Feel That You Need Them Forever
This is perhaps the biggest philosophical difference between coaches. Some build their entire business around keeping clients dependent on them. Every decision requires approval. Every meal needs checking. Every workout must be prescribed.
And the client gradually becomes convinced that they can’t possibly maintain their fitness without professional supervision. I don’t like that approach. Of course, there are people who genuinely benefit from long-term coaching. They enjoy the structure, appreciate the accountability, or simply prefer having someone manage their training.
Nothing wrong with that. But I believe coaching should also be educational. You should gradually understand why you’re training a particular way, how your nutrition works, what your progress means, and how to make sensible decisions independently.
You should become more capable, not less. My ambition isn’t to become someone you can never live without. It’s to become the last trainer you need to hire. There’s a difference.
Does That Mean an Expensive Coach Is Better?
No. Price tells you what someone charges. It doesn’t tell you how good they are. A less expensive coach might be highly knowledgeable, attentive, and perfectly suited to your needs. A premium coach might offer extensive individual support and genuine expertise.
Or they might simply have a better sales funnel. The important question is what you’re actually receiving. If you’re comparing different coaching options, I’ve written a separate article about how much online personal training costs in 2027.
It explains the differences between fitness apps, structured programs, personalized coaching, and premium mentorship.
Five Questions I’d Ask Before Hiring Any Online Trainer
After all these warnings, you might wonder how you’re supposed to choose anyone. I’d keep it simple. Ask the trainer:
- Have you worked with people like me before? Someone with your age, experience, goals, and circumstances.
- How will you decide what training and nutrition I need? Listen for an actual assessment process, not a rehearsed sales pitch.
- What happens if the plan isn’t working? A good coach should have a way to evaluate and adjust it.
- How much personal contact will I receive? Make sure you understand what support is included.
- What should I realistically expect after three months? Be wary of guarantees, but expect an honest discussion of possible progress.
And there’s one more question I’d ask myself. Do I actually like talking to this person? It might sound unscientific, but it matters. You’re potentially going to discuss your body, your habits, your insecurities, your frustrations, and perhaps things you’ve never felt comfortable discussing with anyone else.
You need someone you can trust. Someone who listens without making you feel judged. Someone who can tell you when you’re making a mistake without making you feel like an idiot. And someone who understands that your life doesn’t revolve around training program somebody else created for you.
A Final Thought From Someone Who Does This for a Living
I’m an online personal trainer and nutrition coach. I’m also a man in my fifties who has spent plenty of time dealing with his own body image, fitness struggles, and unrealistic expectations. I know what it’s like to want to change your body and not quite know how. And I know how tempting it can be to believe someone who promises a quick solution.
Changing your body, particularly after 40, doesn’t require a miracle. It requires a sensible plan, patience, consistency, and sometimes a little help from someone who knows what they’re doing.
When considering online personal training, take your time choosing the person you’ll work with. Ask uncomfortable questions. Don’t be impressed by expensive marketing. And don’t feel pressured to sign up simply because someone tells you that today is your last chance.
If you’d like to find out how I work, you’re welcome to book a free consultation.
We’ll discuss where you are, what you’d like to achieve, and what might be standing in your way. You can ask me any of the questions in this article. Including the uncomfortable ones. And if we’re not a good fit, I’ll tell you. Sometimes the most professional thing a coach can do is recommend that you work with someone else.
