Physical self-care is usually described as a collection of healthy habits: rest, movement, sleep, nutrition, and preventive care.
What that framing often misses is that movement is not a single intervention. Walking to the train, stretching for ten minutes, and following a structured exercise program all involve movement, but they do not necessarily produce the same physiological dose or cardiovascular benefit.
That difference is not merely a matter of terminology. It is a measurement problem. Understanding it is the first step toward making physical self-care mean something more precise than “be more active.”
The evidence is not the problem
In 2026, Ekelund and colleagues published an individual participant data meta-analysis in The Lancet using device-measured activity data from more than 135,000 adults across the United Kingdom, United States, Norway, and Sweden.
The researchers estimated the potential population-level effect of small, realistic changes in daily activity. Under a population-wide modelling scenario, adding five minutes per day of moderate-to-vigorous physical activity was associated with potentially averting up to 10% of deaths. Reducing sedentary time by 30 minutes per day was associated with a smaller but still meaningful potential benefit.
These findings should not be interpreted as an individualized prediction that five minutes of activity will reduce any one person’s risk by a specific percentage. They demonstrate something broader: physical activity operates along a dose-response curve, and small changes accumulated across a population can matter.
“Move more” may be directionally correct, but it remains incomplete. Amount, intensity, frequency, and consistency determine the dose being delivered.
The evidence is not the bottleneck. The system for translating it into meaningful individual guidance is.
National Wellness Month got the instinct right
National Wellness Month has helped place self-care—including movement—into mainstream conversation each August. It reinforces the idea that caring for physical health deserves deliberate attention alongside sleep, hydration, nutrition, stress management, and recovery.
That cultural shift matters. Movement should not sit outside the definition of self-care as something separate, technical, or reserved for athletes.
But a gap persists between awareness and clinical specificity. Encouraging someone to prioritize movement does not answer how much activity they need, what intensity is appropriate, how different activities should be combined, or whether their current routine is changing over time.
Asking people to move more is not the same as managing how much movement they are actually accumulating.
National Wellness Month identified the right instinct: movement belongs in the self-care conversation. The measurement and follow-through needed to translate that awareness into a meaningful exercise dose remain underdeveloped.
Cardiac rehabilitation: the proof of concept and its limits
If National Wellness Month represents awareness, cardiac rehabilitation represents the proof of concept—what structured, dosed exercise looks like when it is properly assessed, supervised, and progressed.
Exercise-based cardiac rehabilitation can improve functional capacity and quality of life and reduce cardiovascular mortality among appropriate patients with coronary heart disease. Its effectiveness comes from more than access to a treadmill or exercise class. Programs typically include baseline assessment, individualized exercise prescription, monitoring, progression, education, and follow-up.
It also reaches only a fraction of the people who could benefit from structured exercise support. A 2014 review of cardiac rehabilitation in Canada estimated that approximately 34% of eligible patients participated.
More fundamentally, eligibility is generally triggered after a cardiovascular diagnosis or event. The model was not designed to provide preventive exercise support to the much larger population living with inactivity, elevated cardiovascular risk, diabetes, obesity, or declining fitness before a major event occurs.
This is not a failure of cardiac rehabilitation. It is a structural feature of how healthcare has funded and delivered exercise: as a specialized service after disease becomes clinically visible, rather than as preventive infrastructure available earlier.
The nuance: exercise dose is more than a number
Fitness apps and wearables have made activity highly visible through steps, minutes, heart-rate zones, and workout summaries. But visibility is not the same as an individualized exercise prescription.
The key concept is exercise dose: the combination of frequency, intensity, time, type, and progression used to produce a desired physiological effect.
MET-minutes are one useful way to quantify part of that dose. A metabolic equivalent, or MET, estimates the energy demand of an activity. Multiplying that value by the number of minutes performed creates a common measure that allows different activities to contribute to the same weekly total. For example, 30 minutes of an activity estimated at five METs contributes approximately 150 MET-minutes.
But MET-minutes do not, by themselves, make a prescription individualized.
Consider two 47-year-olds who each accumulate approximately 600 MET-minutes in a week. One is regularly active, has no known cardiovascular risk factors, and completes the activity comfortably. The other has type 2 diabetes, has been sedentary for several years, and experiences limited walking tolerance.
The same recorded weekly volume may represent two very different clinical situations. Their appropriate starting intensity, activity type, progression, symptom monitoring, and need for clinical assessment may differ substantially.
A common measurement unit makes exercise more visible. Clinical context determines what the number means.
This is the gap that neither general wellness platforms nor traditional programs fully occupy: the space between recording activity and managing exercise as a measurable, adjustable clinical behaviour.
What closing the gap requires
Making physical activity clinically meaningful—not simply clinically recommended—requires four elements.
- A baseline functional assessment. Before an appropriate dose can be developed, a person’s current capacity, symptoms, health conditions, limitations, and recent activity need to be understood. Baseline capacity should be assessed rather than assumed from age or appearance.
- A defined exercise dose. Frequency, intensity, time, and type should be translated into an understandable plan. MET-minutes can provide a common measure of weekly volume, but the target and progression still need to reflect the person’s clinical circumstances and goals.
- Longitudinal tracking with adjustment. A dose that is appropriate at the beginning may not remain appropriate as fitness improves, symptoms change, or barriers emerge. Meaningful support requires repeated measurement and the ability to adjust the plan over time.
- Integration with clinical care when appropriate. Activity data that remains isolated inside a consumer app may be invisible to the rest of the care team. In physician-supported care, exercise information should be available in a form that can contribute to a clinical conversation without replacing clinical assessment.
None of these requirements are technologically impossible. They are operationally underdeveloped.
How My Heart Fitness makes movement more measurable
My Heart Fitness was designed to help close the gap between general movement advice and measurable exercise behaviour.
The platform helps translate patient-reported activities into MET-minutes so that walking, cycling, structured workouts, and other forms of exercise can contribute to a common weekly total. Rather than treating each activity as an isolated event, My Heart Fitness allows people to follow how their exercise accumulates and changes over time.
This creates a longitudinal exercise trajectory instead of a series of disconnected workout entries.
In physician-supported settings, My Heart Fitness can also summarize reported activity in patient and physician reports. This helps make exercise behaviour more visible between clinical encounters and provides a more specific starting point for conversations about consistency, intensity, progression, and barriers.
The information does not replace clinical assessment, exercise testing, or an individualized prescription from a qualified healthcare professional. Its role is to make the activity occurring in everyday life easier to measure, interpret, and follow.
The goal is not merely to tell someone that movement is self-care. It is to help them see what that movement adds up to.
Why this moment matters
Two converging forces are creating an unusual window for progress.
First, the rapid growth of GLP-1 and related medications has increased clinical attention on preserving muscle mass, cardiorespiratory fitness, strength, and physical function during weight loss. Medication may influence weight and metabolic risk, but it does not eliminate the need to build and maintain physical capacity.
Second, wearable and remote-monitoring technologies can now collect activity and physiological information throughout everyday life. Yet a 2026 review in the European Heart Journal noted that widespread clinical adoption remains limited by inconsistent measurements, poor integration with electronic health records, and the absence of standardized workflows that help clinicians interpret and act on the data.
The missing piece is not the evidence or the ability to collect another number. It is the clinical architecture that connects movement to a meaningful dose—and makes that dose visible, interpretable, and accountable over time.
That is the role My Heart Fitness is working to support: moving physical self-care from a general intention toward a measurable behaviour that people and their care teams can follow.
Frequently asked questions
What is physical self-care?
Physical self-care is the ongoing set of behaviours that support physical health and function, including movement, structured exercise, sleep, recovery, nutrition, and preventive care. It includes both everyday activity and planned exercise, although those activities are not physiologically identical.
What is the difference between physical activity and exercise?
Physical activity includes any bodily movement that uses energy, such as walking, gardening, household tasks, or taking the stairs. Exercise is a subset of physical activity that is planned, structured, and performed to improve or maintain a specific aspect of health or fitness.
What is exercise dose?
Exercise dose describes the frequency, intensity, duration, type, and progression of activity. MET-minutes can help quantify weekly exercise volume, but they are only one part of determining whether a plan is appropriate for a particular person.
Do everyday activities such as walking count as physical self-care?
Yes. Walking and other forms of everyday movement contribute to physical self-care and can provide meaningful health benefits. The amount of exercise they contribute depends on factors such as duration, pace, terrain, frequency, and consistency.
How much movement is enough for heart health?
General guidelines recommend that adults work toward 150 to 300 minutes of moderate-intensity aerobic activity per week, 75 to 150 minutes of vigorous activity, or an equivalent combination, together with muscle-strengthening activity. Someone who has been inactive, has symptoms, or has a medical condition may need a different starting point and should seek appropriate guidance.
How does My Heart Fitness measure exercise?
My Heart Fitness helps convert reported activities into MET-minutes, allowing different activities to contribute to a common weekly total. It then helps display activity over time so people can see their consistency and overall exercise trajectory rather than viewing each workout in isolation.
