Why do I spike during exercise?

Exercise involves both increased release of glucose from stores in the liver and increased uptake of glucose into muscle to fuel muscle contraction. During high intensity exercise, adrenaline helps your heart ramp up the pumping of blood and it can also cause the liver to release more glucose into circulation than the muscle can absorb causing a temporary glucose spike. Spikes can also occur during moderate or lower intensity workouts if adrenaline is released. Exercise spikes are beneficial as exercise and intense training can improve both fasting glucose and insulin sensitivity over time; each of these adaptations lead to better metabolic flexibility and glucose control. Exercise-associated Lingo Counts shouldn’t count against you. If you log exercise, or your Health Kit indicates exercise coinciding with this spike, Lingo Counts for this spike will be set to zero and no counts will be added to your daily total. If you see that Lingo Counts from exercise aren’t being removed, you can remove these counts yourself. Just:

• Tap the + button below the spike
• Select “remove Lingo Counts.”
