Key takeaways

Regular physical activity helps improve blood sugar levels and reduces HbA1c over time
Exercise works best when planned with your diabetes care team—doctor, sports specialist, and trainer
Physical activity is a complement to insulin therapy, not a replacement
Continuous glucose monitoring can help you see how your body responds to exercise in real time

How Exercise Affects Blood Sugar

A study of 90 people with type 2 diabetes found that those who were physically active showed stronger improvements in blood sugar control compared to sedentary participants. Over 3 to 6 months, active participants saw better reductions in blood glucose levels and HbA1c—a marker of average blood sugar over weeks. Body weight and cholesterol also improved, though more gradually.

While this research focused on type 2 diabetes, the principles apply to type 1 as well: movement helps your body use insulin more effectively and improves overall metabolic health.

Exercise Works Best With a Plan

The research emphasizes an important point: exercise should not be a solo effort. The most effective approach involves teamwork between your endocrinologist, a sports medicine doctor, and a fitness professional or personal trainer. This team can design a movement program tailored to your needs and help you manage blood sugar safely during and after activity.

Physical activity should be viewed as an additional therapy alongside your insulin regimen—it enhances your overall diabetes management but does not replace medication.

Tracking Your Response With Technology

Continuous glucose monitoring (CGM) has made it easier to see how your body responds to exercise in real time. A recent study of people using do-it-yourself CGM found that real-time glucose data helped them spot patterns—like reduced blood sugar swings overnight and after meals—that they might have missed otherwise.

For many people, seeing this feedback on a smartwatch or phone gave them confidence in their diabetes management and helped reduce worry about unpredictable blood sugar changes during activity.

What This Means for You

If you have type 1 diabetes and want to boost your exercise routine, the evidence supports moving in partnership with your care team. Together, you can create a realistic plan, monitor your response, and adjust insulin as needed. Regular physical activity, combined with proper monitoring and professional guidance, can improve your blood sugar control and overall health.
