when your doctor prescribes a workout: the case for exercise as medicine is getting stronger
if movement is medicine, we should treat it that way. we give every other prescription the same seriousness, structure, and investment.

exercise as medicine is starting to receive the recognition it deserves, but it needs to be taken more seriously than 'just go exercise.'

most doctors’ offices use a prescription pad to write medications. but increasingly, in clinics across canada and worldwide, healthcare providers are writing something else: a referral for exercise.
not to a gym, but to a qualified exercise professional—someone trained not just in fitness, but in health, physiology and behaviour change. the result isn’t a workout trend. it’s a public health strategy with growing evidence behind it.
new research confirms what many have long believed, but few systems fully support. when primary care providers formally refer patients to trained exercise professionals, it leads to measurable improvements in cardiorespiratory fitness. in turn, improved fitness reduces the risk of chronic disease, improves prognosis in those who are already sick, and helps people live longer, better lives.
exercise, it turns out, isn’t just a recommendation. it’s a treatment.
why cardiorespiratory fitness matters more than we realize
cardiorespiratory fitness—your body’s ability to take in and use oxygen efficiently during physical activity—is one of the most powerful predictors of long-term health. high levels are associated with reduced risk of stroke, heart failure, hypertension, and even all-cause mortality. improved cardiorespiratory fitness can enhance recovery, resilience and day-to-day function for patients already living with chronic disease.

however, fitness is rarely measured in clinical settings, and structured exercise is seldom prescribed. most patients are told to “move more” or “try to exercise” with little support beyond a brochure or a verbal nudge.
that approach, the data suggests, doesn’t go far enough.
exercise referral schemes—a formal process where primary care providers refer patients to certified exercise professionals for personalized, supervised programs—offer a more structured path forward. instead of vague encouragement, patients get a concrete plan. and instead of being left to figure it out alone, they get expert support.
evidence behind the prescription
a recent systematic review and meta-analysis analyzed 29 studies involving over 6,300 adult participants. the results were precise: exercise referral schemes improve cardiorespiratory fitness. programs that lasted at least 12 weeks and included direct supervision, rather than just physical activity counselling, showed the most substantial benefits.
the gains weren’t huge in scale, but they were significant. even small improvements in fitness can dramatically reduce the likelihood of future complications for a patient with cardiovascular risk factors or existing health conditions. for older adults, the improvements can translate into more independence, better balance, fewer falls and more energy for daily life.

more importantly, these changes were achieved without medication, invasive procedures, or expensive interventions. just time, guidance and movement.
beyond ‘just go exercise’
for decades, public health campaigns have stressed the importance of physical activity. however, failing to embed those messages within healthcare systems has left a critical gap. most patients, especially those dealing with chronic illness, low income, or mobility issues, face barriers that can’t be solved with motivational slogans.
that’s where exercise referral schemes can change the equation. by placing exercise professionals, like physiotherapists or dietitians, within the care pathway, patients can access targeted, science-based support designed around their needs and health status.
these professionals don’t just tell people what to do. they assess baseline capacity, tailor exercise prescriptions, monitor progress and modify plans based on feedback or symptoms. for patients dealing with pain, fatigue or fear of injury, this kind of attention makes the difference between giving up and getting better.
why qualified matters
the success of exercise referral schemes doesn’t come from just telling people to walk more. it comes from integrating certified exercise professionals into the care team. that distinction is key.

qualified professionals, such as those with degrees in kinesiology or recognized certifications, are trained to work with individuals with medical complexities. they understand how to adapt protocols, recognize warning signs and scale workouts in ways standard fitness instructors may not.
this professional oversight not only improves outcomes but also builds trust. patients are more likely to follow through when they feel the recommendation is medical, credible, and safe. they’re also likelier to stick with the program when it is tailored to their pace rather than a one-size-fits-all model.
12-week window of change
the review also highlights something profound but straightforward: duration matters.
programs that lasted 12 weeks or longer were more effective than shorter interventions. that three-month window appears to be a critical threshold, not just for physiological change but also for behaviour change. it is long enough to build endurance, confidence, and habit, long enough to feel results and long enough to make movement part of everyday life.
that insight could shape how healthcare systems design future programs. a few weeks of advice isn’t enough. over time, ongoing structure and support create the conditions for sustainable health improvements.

opportunity ahead
as chronic disease rates rise and healthcare systems strain under the burden, prevention and rehabilitation strategies must evolve. exercise referral schemes offer a practical, evidence-based approach that can be scaled into primary care, especially for aging populations.
the opportunity isn’t just clinical—it’s cultural. embedding exercise professionals into primary care settings normalizes movement as a part of health—not as an optional hobby but as a fundamental intervention alongside medication, therapy and dietary change.
it also reduces the stigma that exercise is only for the fit. when a doctor refers a patient to an exercise professional, it sends a different message: this is for you. this is part of your care. you are not alone in this.
from the clinic to the community
this approach bridges the gap between clinical advice and real-life action. it acknowledges that for many patients, knowing what to do isn’t the issue—learning how to do it, staying safe, progressing and staying motivated.
exercise referral schemes create that bridge. they bring fitness into the realm of public health, and they redefine what it means to treat and prevent disease.

the next step is integrating these systems into healthcare pathways, funding them adequately, and ensuring that qualified professionals are accessible, recognized and supported.
because if movement is medicine, we should treat it that way. we give every other prescription the same seriousness, structure and investment.
and maybe then, walking into a gym or studio won’t feel like a leap—but a natural extension of care, guided by someone who knows just how far you can go and how to help you get there.
