I started taking 3g of pharmaceutical grade fish oil about 1 year ago with 5000IUs vitamin D and 120mcg of K2 MK-7. I don’t “feel” anything but my Garmin is clear that my RHR and VO2max have greatly improved, and yet that’s on 5-6h sleep per night. I’m also definitely less sick.

Now question remains, which of those is responsible for this?

[chiefalchemist]

Or not? Perhap it's the placebo effect?

Note: Not knocking it. I exercise. I take vitamins. Etc. But the more I read, the more I wonder about the mind's role in physical and mental health.

Belief is a power we're not even close to understanding.

could be simply you continuing to work out consistently for a year

Here’s the thing, I don’t work out much, if at all other than cleaning the house and mowing the lawn. Not much has changed on the lifestyle side, overall.

I recently started doing the stepper and noticed the improvement compared to occasional physical activity that I inconsistently do from time to time (e.g. sports outside with the kids).

Edit: typos

How much could you improve your vo2max with that setup and sport?

[jackmott42]

To be clear the question is how much you can improve the Garmin's estimation of your Vo2 max, which is a different thing.
