The Workout Habit That Can Become Harm
If your day begins with a HIIT class and ends with the saintly glow of “I’ve been good,” you’re not alone. Regular movement can lighten stress, settle anxiety, and generally make the world feel a little less like a group chat on deadline. But for a small group of gym-goers, exercise addiction isn’t a punchline or a humblebrag — it’s a real behavioural pattern that can quietly bulldoze daily life.
Researchers in Budapest have suggested that for around 0.3 to 0.5% of gym-goers, working out and the quest for ultimate wellness can tip into unhealthy obsession. And a separate study from Anglia Ruskin University found the risk rises sharply for people with a history of eating disorders — with researchers reporting you’re nearly four times more likely to experience exercise addiction if you’ve previously had anorexia or bulimia.
It’s an uncomfortable twist, because exercise is supposed to be the good bit. The socially approved coping mechanism. The one that gets likes, not concerned phone calls.
Why “Healthy” Can Be a Convenient Disguise
Wellness culture has a curious magic trick: it can make rigid rules look like discipline. Eight hours’ sleep becomes a badge of honour. “Clean eating” becomes a personality. And a workout missed can feel, for some, less like a rest day and more like a moral failure.
That’s what makes compulsive exercise hard to spot — especially during or after recovery from disordered eating. To friends and family, it can look like someone has “sorted themselves out.” Under the surface, the engine can be the same: fear, control, anxiety — just with different gym kit.
As Eating Disorders Awareness Week begins (March 2–8), we spoke to experts about wellness, disordered exercise, and the additional risks for those with a history of eating disorders.
Can Eating Disorders Be Replaced by Exercise Addiction?
Kerrie Jones, a psychotherapist specialising in eating disorders and clinical director of treatment centre Orri, says eating disorders and exercise addiction often share the same roots — and the same function.
“Eating disorders, like exercise addiction, arise when we have lived through an experience – or lots of different experiences – that have taught us that we’re not safe in our day-to-day lives,” she says.
“Obsessing about food, weight or exercise is a behavioural mechanism that has developed as a means of keeping us feeling safe and in control when otherwise we’d feel overwhelmed with fear and anxiety.”
Jones explains that these behaviours can narrow a person’s focus to what feels measurable and manageable — calories, reps, weight, shape — while masking the deeper fear underneath.
“We call these ‘maladaptive’ coping mechanisms, as they develop through seemingly good intentions, but to the detriment of our longer-term physical and mental health.
“Sometimes, when people reach a point in their recovery where they are stable and functioning, they may move from an obsessive relationship to food, to an obsessive relationship to exercise.”
And because exercise is widely applauded — and often actively encouraged — the behaviour can stick around far longer than people realise.
“It’s a much more socially accepted and idolised means of maintaining obsessive behavioural patterns,” says Jones, which means it can linger for years before someone seeks help.
What Drives Exercise Addiction Psychologically?
There’s rarely one neat cause. It’s more often an overlap of biology, social pressure, past experiences, and psychology — with a particular role for trauma and learned patterns of control.
“There’s no one reason or cause why someone might develop an eating disorder or exercise addiction, however, it’s often a combination of social, genetic and psychological factors,” says Jones. “Commonly, we find a negative life experience or traumatic experience at the root.”
Chartered psychologist and Healthspan ambassador Dr Meg Aroll says more research is needed specifically on exercise addiction, but we already know a lot about how behavioural addictions operate — particularly the loop of compulsive thoughts and repeated behaviours.
“We know that it’s important to change patterns of ruminative and compulsive thoughts in people with behavioural addictions, which is why treatments such as cognitive behavioural therapy are likely to be of help.”
In plain terms: it’s not about willpower. It’s about patterns — and treating what’s driving them.
Signs to Watch For: When Training Turns Compulsive
There’s no single template for exercise addiction. People don’t present in one uniform way, and “looking fit” tells you precisely nothing about what’s happening mentally.
But there are common warning signs, especially when exercise becomes less about wellbeing and more about relief, guilt, or control.
Jones says a person might:
- Feel guilt and shame about missing exercise routines
- Keep secrecy around how much they’re exercising
- Continue to workout when ill, exhausted or injured
- Prioritise exercise repeatedly over family, friends, work, and recovery
That last point matters. Training that regularly trumps relationships, rest, or basic health isn’t “dedication.” It’s a red flag waving in fluorescent gym lighting.
Does Social Media Make It Worse?
Social media can be supportive — community can be a lifeline — but it can also validate compulsive habits. A life organised entirely around workouts can look, online, like “motivation,” when the reality might be anxiety management dressed up as routine.
“For people who are predisposed to eating disorders or behavioural addictions, wellness culture can appear to support and condone this type of maladaptive behaviour,” says Aroll.
“However, on its own, wellness and social media culture is not to blame – someone with such conditions will have a complex combination of factors in their life leading to their symptoms, which should be investigated fully and treated professionally.”
Jones adds that if you know you have an addictive personality, it’s worth curating your feed with intent — and unfollowing content that escalates guilt, restriction, body obsession, or punishment narratives.
What To Do If You’re Worried About Someone
The hardest part is saying something — and the most important part is saying it well. Jones recommends addressing it directly, but with care around timing, tone, and what you focus on.
“It’s important to broach the topic with them directly as their physical and mental health may be severely at risk,” says Jones. “Pick a time to talk when emotions aren’t running high, and where possible, try and avoid talking about exercise specifically or the more symptomatic aspects of exercise addiction or their eating disorder.
“Instead, focus your questions and concerns on how they’re feeling, underneath their day-to-day activities.
“Keep in mind that there are specialists out there who can help and the charity Beat has numerous resources on how to have a difficult conversation with someone.”
In other words: aim beneath the behaviour, toward the emotion.
Do We Need a Broader Conversation About “Healthy”?
Here’s the tricky bit. Health professionals rightly champion exercise for physical and mental health. But for people recovering from eating disorders — or with a vulnerability to compulsive behaviours — messaging can land differently. “More is better” can become a permission slip for harm.
“I think there needs to be a broader conversation about what it means to be ‘healthy’ and to live a ‘healthy lifestyle’,” says Jones. “What works for some, may not work for others, particularly if they’ve suffered with an eating disorder in the past and would have trouble maintaining a normal relationship to exercise and food.”
Jones says clinicians assessing physical health need to consider personal history and the intention behind the behaviour.
“If possible, we need to investigate the intention associated with exercise and unpick the feelings that arise before, during and after exercising.”
That’s the real measuring stick. Not calories burned, not streaks kept alive, not the smug serenity of a kale smoothie. If movement helps you live more freely, it’s doing its job. If it’s tightening the cage — especially in recovery — it’s time to call it what it may be: exercise addiction, and something that deserves proper support, not applause.

Exercise is good for you. Brilliant, in fact, by nearly every objective measure. For this reason, the world is full of fit people telling less fit people to do more exercise – but this rarely works. Why?
There’s a quote I love from my chat with experienced trainer, author and all-round sensible chap Ben Carpenter.
“Fitness professionals are hardcore exercise enthusiasts who often don’t know how to empathise with people who are not also hardcore exercise enthusiasts.”
This causes a massive divide between those who exercise and those who don’t.
Those who exercise regularly (group A) often built this habit as a child. Exercising regularly is their default, they are good at it, it feels fantastic, and (as with anyone who has ever hit a dopamine goldmine) they are keen to encourage others to do it too.
But for those who don’t exercise regularly (group B), it doesn’t feel good or natural at first – quite the opposite, actually. This is especially true when a member of group A recommends they start with a high-octane exercise class or hardcore workout programme.
No one is in the wrong – we are all just playing the cards we have been dealt. But there is a solution: start where you are, not where you want to be.
To do this, it is important to realise there is no one-size-fits-all fitness plan. The same workouts will affect people differently depending on individual factors such as genetics, environment and training experience.
This means, when a fitness figure or influencer tells you, “You can look like me by doing exactly as I do,” you would do well to question it.
Instead, it’s best to find a fitness routine that meets you where you’re at. (I think this plan from coach Darren Ellis offers a good framework for getting started, alongside a few options to scale it to your specific needs.)
If you currently don’t do any exercise, adding any new healthy behaviours into your regular daily routine will likely see an uptick in your fitness fortunes. For example, an extra portion of fruit and veg, a walk or a short mobility session.
If you’re a seasoned runner or gym-goer wanting further fitness progress, you need to upgrade the intensity of your existing workouts. For example, quickening your paces during interval sessions or adding a few extra kilos to the barbell for your next set of squats.
In both situations, picking appropriate workouts for you and progressing them in line with your fitness levels is the key to long-term success.
It’s also worth noting that exercise doesn’t always feel good at first, especially if you bite off more than you can chew.
I remember listening to elite coach Chris Hinshaw describe a running session he did with a former professional powerlifter who wanted to learn how to sprint. Powerlifters are juggernaut figures who excel at lifting heavy barbells, but they are often less adept at moving their own bodies.
So, Hinshaw gave his client a beginner sprinting drill he knew the athlete could excel at. “The first bite of the apple has to taste good,” Hinshaw later explained. Spurred on by his early success, the motivated athlete continued to work on his sprinting.
Perhaps hypocritically, given the intro, I am now going to tell you that exercise does ultimately end up feeling inexplicably good. My recent interview with 47-year-old Irishman David Keohan reinforced this belief.
“In my 20s I was into art and music and drinking and smoking,” he told me. “I was obese and unhealthy, mentally and physically. Then you get to your 30s and your body says, ‘Hold on a second, we need to start doing something about this, kid’.”
So, he went and bought a pair of trainers, fending off questioning glances from the man behind the till. Within six months he had run his first marathon. In the next few years he became a world champion at lifting kettlebells. Then, during Covid lockdowns, he started lifting huge boulders in his garden and stumbled across the lost Irish culture of stone lifting (this is one of my favourite recent interviews).
“I got bitten by the bug of feeling good,” Keohan continues. “Before, I never knew what feeling good felt like, if that makes any sense? But once you start to feel good, it’s amazing, and you realise how bad you felt for the last 10 years.”
Now, you don’t have to lift 170kg stones in your back garden to get in shape. This is an extreme example. But it does pay to do something slightly challenging (for you) on a fairly regular basis – whether that’s a short walk or a gnarly workout.
Because eventually, I’m afraid to say, exercise does have a tendency of making you feel rather good.

This is a tough question to answer because it depends on what kind of exercise bikes you’re into. But based on the popular exercise bikes and the bikes that resemble Peloton the most during testing, it would have to be NordicTrack, BowFlex and Echelon.
“,”quickTake”:””,”canCollapse”:”true”,”collapseOnPageLoad”:”false”,”canTruncate”:”true”,”truncateOnPageLoad”:”false”},{“question”:”What should I look for when buying an indoor exercise bike?”,”answer”:”
You’ll want to consider cost, size, display screen and whether you want to pay for a monthly subscription. If your main goal is to simulate the experience of riding a Peloton, you’ll want to get a bike that offers similarities, like the NordicTrack S24.
“,”quickTake”:””,”canCollapse”:”true”,”collapseOnPageLoad”:”false”,”canTruncate”:”true”,”truncateOnPageLoad”:”false”},{“question”:”Which muscles does indoor cycling work?”,”answer”:”
Indoor cycling is a full-body workout. It targets your core, upper body, back, glutes, quadriceps, hamstrings and lower legs. Some bikes also include weights so you can more specifically target muscle groups in your arms.
“,”quickTake”:””,”canCollapse”:”true”,”collapseOnPageLoad”:”false”,”canTruncate”:”true”,”truncateOnPageLoad”:”false”},{“question”:”Is a built-in or BYO screen better?”,”answer”:”
The most eye-catching aspect of the Peloton exercise bike is its 21.5-inch HD touchscreen. For a Peloton alternative, you want the exercise bike to have a screen or tablet compatibility. Some exercise bikes like NordicTrack and Echelon come with the large touchscreens, but other brands like BowFlex require you to use a tablet to access classes. The smaller screen may not draw you in as much, but it’s a personal preference whether you want the touchscreen.
“,”quickTake”:””,”canCollapse”:”true”,”collapseOnPageLoad”:”false”,”canTruncate”:”true”,”truncateOnPageLoad”:”false”},{“question”:”Is a subscription necessary?”,”answer”:”
Peloton charges $44 a month for its All-Access membership. As you can tell by the Peloton alternatives list, other brands offer similar memberships through their app subscriptions. You can use any of these bikes independently, but if you want to get the most out of a bike, you may want to consider signing up for a membership as well. The other plus is most of these exercise bikes connect to third-party apps, so there are different ways to use them.
“,”quickTake”:””,”canCollapse”:”true”,”collapseOnPageLoad”:”false”,”canTruncate”:”true”,”truncateOnPageLoad”:”false”},{“question”:”What’s better, Echelon or Peloton? “,”answer”:”
This depends on the type of experience you’re looking for. An Echelon is a slightly more affordable option ($300 cheaper), and it’s easy to follow like a Peloton. But a Peloton has a rotating screen, and its instructors tend to be more high-energy than Echelon’s. If the classes matter the most to you, an Echelon membership is slightly cheaper than Peloton’s, so you may want to spend the extra money on the classes and bike if it’s in your budget.

‘Exercise is usually viewed through the lens of physical appearance, the number on the scale and the size of your jeans,’ says Dr Ramon Velazquez, neuroscientist and scientific advisor at Mind Lab Pro. ‘But you cannot move your body without moving your brain. Exercise is not primarily a body intervention – it’s a brain intervention, and the changes you see in your waistline or muscles are side effects of what’s actually going on neurologically every time you move your body with intention.’
Indeed, while a huge body of research shows how crucial movement is for physical health – from protecting our hearts to reducing cancer risk – an increasing number of studies are highlighting the significant cognitive benefits of exercise, from boosting memory and reducing dementia risk to restoring neuroplasticity (the brain’s resilience in adapting to new information, behaviours and sensory input).
But what exactly should that look like in practice? And how should you structure your weekly routine to maximise the brain health benefits of exercise? Dr Velazquez has the answers below.
The workouts
Zone 2 cardio
‘Zone 2 cardio is the most underrated form of exercise. People usually dismiss it because they feel like they aren’t doing enough if they’re not drenched in sweat or gasping for air,’ says Dr Velazquez. ‘It’s a type of activity where you move at a pace that elevates your heart rate, but you can still have a conversation with the person next to you.’
Indeed, a recent review of more than 258,000 people found that even low- to moderate-intensity exercise performed for less than 30 minutes twice a week improved general cognition, memory and executive function (the mental processes involved in planning, focus and decision-making) in as little as one to three months. Dr Velazquez recommends light jogging, swimming and cycling. ‘From a neurological perspective, this type of exercise consistently increases blood flow to the brain over a prolonged period of time,’ he explains. ‘This is important because it helps deliver nutrients to the regions that are most vulnerable to ageing.’
Such exercise, adds Dr Velazquez, also supports the glymphatic system – the brain’s waste clearance system that removes proteins and cellular waste linked to neurodegenerative diseases such as Alzheimer’s.
Strength sessions
‘Strength training is also extremely important for longevity. Strong muscles produce and release hormones and signalling molecules that directly influence the brain,’ says Dr Velazquez. ‘Muscle mass starts declining from your mid-thirties via a process called sarcopenia, and as the muscle disappears, so does the neurological signalling it produces.’
Two to three weekly sessions is the minimum needed to make a difference, he adds. ‘The sessions don’t need to be long – 45 minutes of focused, compound movements is enough.’ Think: squats, deadlifts, rows and presses – ‘exercises that recruit large muscle groups and produce the strongest possible neurochemical response’.
VO2 max training
‘VO2 max – the maximum amount of oxygen your body can consume and use during intense exercise – is now one of the most powerful predictors of long-term survival ever identified in the research,’ says Dr Velazquez. ‘Most people assume that blood pressure and cholesterol are the numbers worth paying attention to when it comes to how long they are going to live, but VO2 max is more predictive than either of those – a low VO2 max is not just a fitness problem, it’s a mortality risk.’
To improve this metric, Dr Velazquez advises introducing high-intensity exercise – where you’re working at near-maximum capacity for short bursts – once or twice weekly, adding that ‘a simple and highly effective routine would be 4-6 intervals of one minute at hard effort followed by two minutes of recovery’.
‘It will be uncomfortable, but that’s the feeling you need to chase to make this exercise effective, and the physiological stress of those intervals drives adaptations that are cardiac, vascular and neurological.’
Example weekly workout routine
‘Zone 2 is the base of the pyramid, VO2 max training is the peak. You cannot build a high peak without a wide, solid base, which is why all three pillars work together,’ says Dr Velazquez, who gives an example of an effective weekly routine below.
Monday
30-45 mins strength, eg, squats, deadlifts, rows, presses.
Tuesday
Zone 2 workout, eg, light jog or swim.
‘The key is finding an enjoyable activity that raises your heart rate, but not to the point where you’re gasping for air.’
Wednesday
30-45 mins strength.
Thursday
Zone 2 workout.
Friday
30-45 mins strength + VO2 max training afterwards.
Saturday
Longer zone 2 workout (around 60 mins).
‘I would suggest working out in nature, since a natural environment and exercise are a perfect combination for lowering cortisol.’
Sunday
Rest day.
‘Rest is not the absence of progress, it’s a necessary part of keeping the progress going.’
‘The brain responds to every single session. It’s tracking the pattern, not the performance. And the earlier in life you establish that pattern, the more of your brain you get to keep.’
