For a few nights, my lowest nighttime HR has been much lower than usual at 60. Might it be that my body is already adapting favorably to cardio training? I sure did not expect changes so fast. Maybe these are outlier measurements. We will see how it goes.

I now have a new pair of minimalist shoes specifically for Orangetheory fitness where they are narrow enough to use with the foot straps of their water rowers. My HOKAs were too wide. I do not plan on walking outside in the new shoes because I know that my feet are not ready for minimalism: they need that super supportive structure of the HOKAs.
