Does an evening session still show up the next morning? Three weeks, two sessions a week, and a look at the fasting value.
What I did
Upper body, lower body, back — around an hour, finishing by half past seven. On the other days no training. I compared the fasting readings on mornings after a session with those after a rest day.
What I saw
The mornings after a session were around 16 mg/dl lower. The overnight curve also ran flatter.
What might explain it
Muscles take up glucose for hours after training, largely without insulin. That effect is well described. How much of my difference comes from it and how much from other factors, I cannot say.
What I keep from it
Evening sessions suit my schedule. That they seem to help the next morning makes it easier to keep going.
The stated magnitude is a personal observation from my sensor history. The complete reproducible raw-data record for the period, comparison days and evaluation is not yet available for this release. The number is therefore not treated as confirmed research, generally transferable or a recommendation.
A single observation with my own sensor. It shows what happened to me — not what applies generally. Sleep, stress and the previous day influence every reading.
Key points
- Three weeks, two sessions a week: fasting readings around 16 mg/dl lower.
- The overnight curve also ran flatter.
- Post-exercise glucose uptake by muscle is a documented mechanism.
- One person, three weeks — no proof of anything.
Single observation, not a study.
The values in this article come from my own sensor (FreeStyle Libre 3) and are a single-case observation (n = 1) – they show a pattern in me, not a rule for you. Every statement is labelled as established, plausible or open, and proximity in time never counts as proof of a cause. How I handle time windows, sensor lag, influencing factors and approval is collected on one page. Read the methodology
