Perimenopause and the routine that no longer fits
The habits that worked at 35 stop working at 45. That's not failure. That's biology.
Around 40, a quiet thing happens. The morning workout that used to leave you energized starts leaving you depleted. The two glasses of wine that used to be fine now ruin Tuesday. The 90-minute focus block that produced your best work no longer holds. You blame yourself, because nothing official has changed.
Something has changed. Perimenopause, the years-long ramp into menopause, shifts hormones, sleep architecture, recovery time, and stress tolerance — sometimes a decade before any obvious symptom appears. The old routine isn't broken. The body underneath it is different.
The honest move is to grieve the old version, then redesign. Strength training matters more, not less. Sleep tolerance for late nights drops. Caffeine windows narrow. Recovery between hard sessions stretches from one day to two or three. None of this is decline — it's recalibration.
Most perimenopausal women describe the same realization: 'I can do less than I used to, but the less is more honest.' The new routine is shorter, gentler, more deliberate. It's also harder to skip, because the cost of skipping shows up faster.
If your routine has stopped fitting and you're in your forties, the routine isn't the problem and neither are you. The body is asking for a different shape. Build it. Forgive the old one. Move on.
