Exercise is a powerful tool for managing blood sugar, especially for people with diabetes. But with so many options: —walking, weightlifting, or high-intensity workouts—choosing the right one can feel overwhelming. This blog breaks down how different exercises affect your blood sugar, offering clear guidance based on scientific research to help you pick the best fit for keeping your levels in check.
Main type of exercise
- Aerobic Exercises: Think walking, running, cycling, or swimming. These get your heart pumping and can lower blood sugar during and after activity by improving insulin sensitivity. A study in Diabetes Care found moderate-intensity aerobic exercise helps reduce blood sugar in type 2 diabetes.
- Resistance Exercises: These include weightlifting and bodyweight moves, building muscle mass which uses more glucose. Research in the British Journal of Sports Medicine shows resistance training can lower HbA1c levels, improving long-term blood sugar control.
- High-Intensity Interval Training (HIIT): Short bursts of intense exercise followed by rest, like sprinting then walking. A review in Sports Medicine suggests HIIT can improve glucose control, potentially more efficiently than steady aerobic workouts.
Intensity and Duration
The American Diabetes Association (ADA) recommends a mix of both aerobic and resistance exercises for best results. Aim for at least 150 minutes of moderate aerobic exercise weekly, spread over at least three days, with no more than two days without activity. Add resistance training at least twice a week, focusing on major muscle groups.
If you can only pick one, choose based on what you enjoy and can stick to. Walking is a great aerobic option, especially for beginners, with studies showing it improves blood sugar control. HIIT might work if you’re short on time, but it’s intense and may not suit everyone, so check with your doctor first. Using a continuous glucose monitoring (CGM) device such as Ottai CGM can help track blood sugar changes during exercise in real time, making it easier to adjust activity or medication.
Step Up and Shine
Whether you’re just starting to manage your blood sugar or looking for new ways to keep it steady, picking the right exercise is a huge step forward. With tools like the Ottai CGM, you can see in real-time how every walk, lift, or HIIT session impacts your levels, giving you the confidence to take charge of your health. Keep at it, find your groove—every move you make is cheering on a stronger, healthier you!
