Exercise appears in nearly every major guideline for type 2 diabetes. Yet it is still often delivered as general advice rather than managed as part of treatment: try to move more.
That gap is not about physicians failing to recognize the value of exercise or patients failing to understand it. It is an operational problem. A recommendation is easy to document. A measurable, individualized exercise plan is much harder to deliver, monitor, and adjust between clinical visits.
Understanding that difference is the first step toward closing the gap.
The evidence is not the problem
In 2011, Umpierre and colleagues published a systematic review and meta-analysis in JAMA examining randomized trials of exercise in people with type 2 diabetes. Structured aerobic, resistance, or combined exercise training was associated with meaningful reductions in HbA1c.
The dose mattered. Programs providing more than 150 minutes of structured exercise per week were associated with an average 0.89 percentage-point reduction in HbA1c, compared with 0.36 percentage points for programs providing 150 minutes or less. Physical activity advice was associated with improvement only when it was combined with dietary advice.
Advising someone to exercise is not the same intervention as defining, delivering, and monitoring an exercise dose.
The evidence is not the bottleneck. The system is.
The integrative solution—and why it still falls short
The American Diabetes Association’s 2016 position statement on physical activity and exercise, building on earlier joint guidance with the American College of Sports Medicine, was an important step forward.
It established specific, evidence-based targets: regular moderate-to-vigorous aerobic activity, resistance exercise on multiple days each week, and avoidance of prolonged gaps without activity. It also recognized that recommendations must account for complications, medication use, baseline fitness, and individual health status.
That guidance gave clinicians a defensible basis for discussing exercise with the same specificity used for other parts of diabetes care. But a gap persists between the guideline and the clinical workflow. A position statement can define a recommended dose. It cannot determine whether a particular patient completed it, whether the intensity was appropriate, or whether the plan should change as fitness, symptoms, glucose patterns, or medications change.
Asking the question is not the same as managing the answer.
The ADA guidance established the clinical vocabulary. The infrastructure to translate that vocabulary into a tracked and adjustable prescription remains underdeveloped.
The proof of concept—and its limits
If clinical guidance represents the aspiration, supervised exercise programs represent the proof of concept: what exercise therapy can look like when the dose is actively delivered and monitored.
Programs combining aerobic and resistance training can improve glycemic control, and greater volumes of supervised exercise have been associated with larger reductions in HbA1c. The value comes not only from access to exercise. It comes from progression, monitoring, feedback, and accountability.
But supervised programs are difficult to deliver as a routine component of care for a condition as common and long-lasting as type 2 diabetes. They require scheduled sessions, trained personnel, suitable facilities or virtual supervision, and sustained participation.
Most diabetes management occurs between visits, when the patient is making daily decisions without a structured feedback loop connecting activity to glucose control, cardiovascular risk, symptoms, or functional capacity.
This is not an isolated program failure. It is a structural feature of how healthcare has treated exercise: as a recommendation or time-limited program rather than a continuously managed behaviour.
The nuance most platforms miss
Step-tracking apps and generic fitness platforms have made movement more visible. But access to activity data is not the same as management of exercise dose.
The key concept is exercise dose: the combination of type, intensity, duration, timing, frequency, and progression needed to produce a physiological response for a particular person.
Consider two 58-year-olds with type 2 diabetes. One is a former runner with preserved functional capacity and no exercise-limiting complications. The other has been sedentary for a decade and has peripheral neuropathy and limited walking tolerance. A generic instruction to complete 150 minutes per week does not create the same intervention for both people.
The first person may need a program that builds on existing aerobic capacity and adds progressive resistance training. The second may require clinical assessment, a more gradual starting point, closer monitoring, and alternatives to prolonged weight-bearing activity. The target may eventually be similar, but the pathway, pace, and safety considerations are not.
This is the gap that neither generic wellness platforms nor a one-line clinical recommendation fully occupies: the space between telling someone to exercise and managing exercise as a measurable, adjustable clinical behaviour.
What closing the gap requires
Making exercise clinically meaningful for diabetes—not simply clinically recommended—requires four elements.
- A defined, individualized prescription. The plan should specify the type, intensity, duration, frequency, and progression of activity in relation to baseline fitness, complications, symptoms, and treatment goals.
- A way to verify the delivered dose. Without consistent tracking, clinicians cannot distinguish between a plan that was ineffective and a plan that was never completed. Activity data should show what occurred, at what intensity, and how consistently.
- A feedback loop connecting activity to outcomes. Exercise should be interpreted alongside measures such as glucose patterns, HbA1c, blood pressure, weight, symptoms, and functional capacity. The purpose is not to claim that every short-term change was caused by exercise, but to support better-informed adjustment.
- Integration with the rest of diabetes care. Exercise does not occur separately from medications, nutrition, sleep, complications, or cardiovascular risk. The care model should help patients and clinicians see those relationships rather than leaving the patient to integrate several disconnected streams of advice and data.
None of these requirements are technologically impossible. They are operationally underdeveloped.
How My Heart Fitness supports a more measurable approach
My Heart Fitness was created to help make exercise behaviour visible between clinical encounters. It translates reported activity into intensity-adjusted MET-minutes, tracks changes over time, and helps patients understand how their activity contributes to a weekly target.
In physician-supported care, My Heart Fitness reports can help clinicians see the exercise patients report completing between appointments. The information is intended to support—not replace—clinical assessment, individualized exercise guidance, medication management, or diabetes care.
This creates a more useful starting point for the clinical conversation. Instead of asking only whether a patient has been “more active,” the patient and clinician can discuss the amount, intensity, consistency, and trajectory of activity over time.
Why this moment matters
Two converging forces are creating an unusual window for progress.
First, increasingly effective glucose- and weight-lowering medications have made it even clearer that glucose control alone is not the full therapeutic goal. Strength, cardiorespiratory fitness, physical function, and cardiovascular risk still require attention.
Second, diabetes care has become more data-rich between visits. Glucose monitors, wearable devices, and digital platforms can collect information continuously, but activity data and clinical data still rarely meet within a single workflow that supports interpretation and adjustment.
The missing piece is not the evidence or the ability to collect more data. It is the clinical architecture that connects exercise behaviour to diabetes management—and makes that behaviour visible, interpretable, and accountable within the care system.
That is the role My Heart Fitness is working to support: turning exercise from a general recommendation into a measurable behaviour that patients and clinicians can follow over time.
Frequently asked questions
How does exercise help with type 2 diabetes?
Exercise increases glucose uptake by working muscles and improves insulin sensitivity during and after activity. Over time, structured aerobic and resistance training can improve HbA1c, blood pressure, fitness, strength, and other cardiovascular risk factors.
Why is advice to “move more” often not enough?
The advice does not specify the type, intensity, frequency, or progression of activity, and it usually does not create a way to verify what was completed. Without measurement and follow-up, the clinician cannot tell whether the dose was adequate or how it should change.
What does “exercise dose” mean?
Exercise dose is the combination of type, intensity, duration, frequency, timing, and progression used to produce a desired physiological effect. The appropriate dose depends on baseline fitness, complications, medications, symptoms, and treatment goals.
Does walking count as exercise for blood sugar control?
Yes. Walking can improve postmeal glucose control, especially when performed at a sufficient intensity or timed after meals. It is often most effective as one part of a broader plan that also includes resistance exercise and progression over time.
Can exercise replace diabetes medication?
Exercise is an important part of diabetes care, but it should not be treated as an automatic replacement for medication. Some people may require less medication as their health changes, but treatment adjustments should be made with the clinician managing their diabetes.
