Yeah, I think I'm probably over thinking things. It was just a suprise to sit in the office and notice a 55 bpm and then I checked the historic data. If I recall correctly I used to be at 80 - 90 before. On the upside I don't think I've ever been this fit before.
If your resting heart rate is dropping from what it used to be it is usually a good sign.
Another good measurement is looking how quickly your heart recovers after exercise, typically a faster drop is indicative of being fitter.
As another said though, I have seen some guys with really high resting heart rates who are exceptionally fit, and some with low who are not.
Being sick can also change this, normally if my resting heart rate is higher than normal, around 10bpm higher, I know im getting sick or have over trained and take it easy. Oddly enough, when I was really really sick a few years ago, my liver and kidneys were packing up and I got covid at the same time, my heart rate was scary low, it wouldnt go above like 75 and sitting was in the low 40's. I felt like I was on a go slow.
