During exercise, our glucose typically does increase, sometimes even up to 50 points. This is normal and okay! The magnitude of the spike in glucose depends largely on your current energy state (fasted vs fed). If you are fasted during your workout, your body will likely need to break down glycogen to provide energy to fuel the workout. In a fed state, your body will likely have enough energy from food to fuel the workout. 

The type and intensity of the workout can also play a role in your glucose response. Higher intensity and anaerobic exercise typically results in a larger glucose spike, as the body must create energy to meet the body's demands. Gradual decreases or steady glucose values are often observed when engaging in steady-state cardio or zone 2 training, as the body is equipped with enough energy to fuel the workout. 

We encourage you not to be alarmed if you see a spike from exercise! Although the spike in exercise may affect your overall glucose average, you should see a pattern of decreased glucose values the rest of the day after exercising (and even the next day!). Movement of all types, durations, and intensities can help improve insulin sensitivity, increase glycogen storage space, and reduce glucose production.
