I wanted to post this image because it’s a great visual representation of muscle glycogen getting replenished during the night, shortly after exercise.
You can see 3 distinct drops on this trace. Each rise in the trace is from drinking juice to get back up.
This is why I frequently mention the importance of post-exercise carb replenishment. When you use it, your body will replace it. So getting sufficient carbs after you finish your exercise is extremely important. The drops demonstrate how the body is pulling glucose out of the blood to replace the used muscle glycogen.
Picture the seagulls from Nemo, squawking “Mine! Mine! Mine!” as the muscles desperately grab what they can to replenish.
