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.
