Everyone’s got wearables now, but most people don’t know what they’re actually looking at.
VO₂ max is a solid marker for aerobic health and longevity.
�But if you’re already reasonably well trained, it often moves slowly. That doesn’t automatically mean you’re not getting fitter.
Instead of staring at one number every week, look at the stuff that matters day to day:
✅ Are your run times improving?�✅ Are you handling more weekly volume?�✅ Do you feel better while you’re running? (less heavy, less cooked, better recovery)
If your VO₂ max only nudges up a tiny bit over 12 months, don’t panic.�If you’re running faster, running more, and feeling better doing it, you’re fitter.
