Greg Nuckols wrote an article two weeks ago about various ways of testing a person’s recovery with the aim being to regulate training intensity based off of how recovered one is. I believe you have also written about this topic in the past.
My question is, what types of tests can I, or anyone else, do to determine the amount of glycogen in my muscles to determine how many grams of carbohydrates I should eat? I notice when I look very flat (one or two days without a significant amount of carbs), when I should eat more carbs or bloated (like after thanksgiving) when I should cut back a bit for the next day or two. However, I can’t really tell where my glycogen stores are at unless I am at the two extremes that I just mentioned. Any ideas besides looking in the mirror?
