The current status
The idea behind it
I want to make two things visible: first, that continuous training over months does more than any single perfect week, and second, how that shows up concretely in my numbers. For this I combine two pillars:
- Endurance, regular cycling on the Peloton (including live rides and personal records).
- Strength, the gym during the week as a supplement, because more muscle mass supports insulin sensitivity long-term.
This is accompanied by my CGM (FreeStyle Libre 3), which shows me the time in range: for me the most honest everyday metric.
The plan for the series
Instead of an endless report, the documentation appears as a series in editions. Each edition is short and focused. This page here stays the overview and is updated monthly.
All editions
The starting balance: five months in the saddle
Where I stand since February: the training routine, my 30-minute Peloton record (285), the most active day so far (almost 48 km from walking and cycling) – and why I am now adding strength training. → Read the edition
The first full month with metrics
For the first time with concrete numbers: average time in range, weight trend and how the combination of cycling and strength feels.
In short, regular check-ins I answer questions about training, values and how I feel. The monthly editions grow out of that. All values are my real records (Peloton app, Apple Health, FreeStyle Libre 3). Where I estimate something or am not sure, I say so.
This series is a lot about training. For people on insulin or sulfonylureas, exercise is not a harmless tool: it can lower blood sugar sharply – even hours later and at night – and trigger hypoglycaemia. I live without medication; anyone who takes some discusses training volume and possible adjustments with their care team.
The metrics I track
- Training: kilometres, time, watts/output, personal records (bike); sessions and focus areas (strength).
- Time in range (TIR): the share of CGM values in the target range: my most important everyday metric.
- Weight & body composition: the trend over the months (see also Losing weight & body composition).
- HbA1c: the long-term lab value, as soon as new checks are available (see HbA1c explained).
Key takeaways
- Long-term documentation (n=1) since February 2026, honest, not a controlled study, no promise of cure.
- Two pillars: endurance (Peloton) + strength (gym).
- Most important metric: time in range from the CGM; plus training, weight, HbA1c.
- Appears as a series in monthly editions – this page stays the overview.
- Goal: to hold type 2 diabetes in remission without medication.
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
