I've taken a few days off here and there. What had happened I believe is that I was basically starving myself and my metabolism had slowed way down. I actually did hit the low 30s back in October when they put me under for my collarbone surgery, but who knows what the effects of the drugs were... My point is just that there are many things that go into that number and you cannot necessarily say that fitter gives you a lower HR number. And I actually rode more then than I am riding now...
Well, that may be true, but I guarantee that if you never road a bike, you would have a RHR in the 60s right now.
