ACC urges clinicians to treat exercise as core cardiovascular therapy
A new scientific statement from the American College of Cardiology places exercise inside the treatment plan for cardiovascular disease, not on the margins of wellness advice. Published in the Journal of the American College of Cardiology, the guidance argues that regular physical activity and improved cardiorespiratory fitness can increase exercise capacity, reduce hospitalizations, and improve quality of life.
The timing of that message matters because low fitness carries prognostic weight on par with long-recognized risks such as smoking, high blood pressure, high cholesterol, and diabetes. In practical terms, cardiorespiratory fitness reflects the body’s ability to deliver oxygen to working muscle during sustained activity, and poor performance on that measure often tracks with higher future cardiovascular risk.
Exercise should be prescribed alongside other cardiovascular treatments, not after them.
Small increases in activity can still move the risk curve
The statement pushes back against the idea that heart protection depends on extreme athletic goals. People who are inactive do not need to reach marathon-level training to gain benefit, and the threshold for meaningful change may be lower than many patients assume. Data cited in the guidance link roughly 5,000 to 7,000 daily steps with clinically important improvements and substantial reductions in cardiovascular and all-cause mortality for many adults.
That finding has bedside value because it changes the first conversation. A sedentary patient who hears only about 10,000 steps may disengage before starting; a patient who hears that a lower, achievable target can still matter may be more likely to move, repeat the behavior, and build tolerance over time.
The physiology is straightforward. Repeated movement improves oxygen delivery, conditions skeletal muscle, and raises overall functional reserve. In cardiovascular care, that can translate into better exercise tolerance, fewer symptom-limited days, and a stronger platform for rehabilitation and disease management.
Why fitness belongs beside blood pressure and cholesterol
Jonathan Myers, PhD, chair of the statement’s writing committee and a health research scientist with the Palo Alto VA Healthcare system, described exercise as a fundamental part of cardiovascular care rather than a lifestyle option. He said clinicians routinely prescribe medications for blood pressure, cholesterol, and diabetes while often failing to prescribe one of the most effective interventions available: physical activity.
Myers also framed the public-health message in plain terms: people do not have to run marathons or join a gym to benefit. Even modest increases in daily activity can produce meaningful improvements in health, and the most realistic plan is the one a patient can actually sustain.
Personalized prescriptions fit the patient better than fixed targets
The ACC statement emphasizes individualized exercise planning. Age, cardiovascular condition, symptoms, functional capacity, treatment goals, and preferences all shape the right prescription. A person recovering from heart disease does not need the same plan as a stable adult trying to prevent it, and a one-size-fits-all approach ignores the real variation seen in clinic.
This individualized model is especially important in patients with symptoms or known cardiovascular disease, where activity must be matched to tolerance and safety. In asymptomatic or clinically stable people, routine exercise testing is not necessary before starting activity. Testing can still be useful when clinicians need to define exercise capacity or construct a more precise prescription.
The logic here is clinical rather than cosmetic. Exercise only helps when it is usable. Plans that ignore symptoms, fatigue, disability, or patient preference tend to fade quickly, while plans built around what a person can safely repeat are more likely to endure.
Aerobic work and resistance training serve different purposes
The statement also makes room for both aerobic and resistance exercise. Walking, cycling, and similar aerobic activities can improve cardiorespiratory fitness. Resistance training adds a different layer of benefit by preserving or building muscular strength.
For most adults, the two should work together. Aerobic exercise supports endurance and oxygen handling, while resistance training helps maintain physical function, which matters for independence, rehabilitation, and the capacity to stay active over time. In cardiovascular medicine, that combination may support treatment goals that reach beyond the heart muscle itself and into everyday function.
Technology may help patients stay engaged
Wearable devices and virtual or home-based rehabilitation programs may strengthen adherence, especially when used with structured programs such as cardiac rehabilitation. These tools can help patients monitor activity, track progress, and stay connected to a plan when traditional center-based options are difficult to attend.
Their value is not in novelty. It is in continuity. Cardiac rehabilitation works best when patients can stay engaged, and technology may provide another route to participation when logistics, transportation, or scheduling create barriers.
Long-term adherence remains a critical question in routine care, and digital support does not erase the need for coaching, follow-up, and realistic goal setting. Still, the statement recognizes that modern exercise prescription can extend beyond a paper handout.
Why exercise remains underused despite strong evidence
Myers pointed to several reasons exercise remains under-prescribed in cardiovascular care, including limited clinician training in exercise counseling. That gap leaves a gap in practice: a therapy with clear cardiovascular benefits often receives less formal attention than drug therapy, even though the two can work side by side.
The result is a missed opportunity at the bedside. A patient may leave with instructions for medication adherence, diet changes, and follow-up testing, but without a structured plan for movement that could improve fitness and lower risk. The ACC statement is an attempt to close that gap by giving clinicians a framework for exercise prescription rather than vague encouragement.
The evidence base backing that shift is already substantial. Regular physical activity improves cardiovascular health, lowers chronic disease risk, and supports longer life. The remaining task in many clinics is not proving that exercise works, but translating that knowledge into a prescription that is specific, safe, and achievable.
Clinical practice now needs more than encouragement
The practical message is clear: movement should be treated as part of cardiovascular treatment planning from the start. Modest activity goals may be enough to begin, and the best plan is the one tailored to symptoms, capability, and personal goals.
For clinicians, that means moving exercise from advice to prescription. For patients, it means the entry point can be small, realistic, and still meaningful.
The statement does not solve every implementation problem, and adherence will continue to depend on access, follow-up, and patient readiness. The harder part is making exercise prescription routine in everyday cardiovascular care, where medications have long held center stage and movement has too often been left as an afterthought.
