What are safe blood sugars to have during exercise?

Understanding the relationship between exercise and blood sugar levels can be a complicated thing. That’s why we’re here to help! It’s so important to frequently monitor your blood sugar throughout each workout session to see how each exercise affects your body!

Different exercises are known to either increase or decrease someone’s blood sugar, and depending on someone’s blood sugar and medication profile, their GlucoseZone program will vary. "The Zone" is a range of blood sugar levels between 100 and 154 mg/dl. Getting, or keeping, your blood sugar levels in this range can help you to achieve an A1c of 7.0 or below. To learn more about blood sugar and exercise.

The key aspect of the GlucoseZone program is the blood glucose measurement at the start of the exercise session. Depending on someone’s blood sugar it may or may not be safe to exercise and it may or may not be safe to perform certain exercise. The app will guide someone based on their starting glucose level when they enter the app and during if the activity is longer than 30 minutes.

• Below 100 mg/dl : Caution!  It may be unsafe to exercise, consume a healthy, fast acting carb such as an apple or juice box.
• 100 – 250 mg/dl: Green Light!  For most people living with diabetes, this is a safe range for starting exercise.
• Above 250 mg/dl : Caution!  It may be unsafe to exercise, consider making an adjustment prior to exercise to slightly bring down that number to a safer range.
• Above 300 mg/dl: Red Light!  Your number is too high to exercise, consider postponing exercise until your glucose levels are within a safe range.
• #glucosezone: 100-154 mg/dl - of course everybody is different and so are their A1Cs. However, here at the GlucoseZone we consider 100-154 to be a target range due to the fact that a blood sugar of 154 translates to an A1C of 7.0. For individuals living with pre and type 2 diabetes, the lower your A1C the better your chances of reducing and reversing your diabetes!
