Resting is around 40-45 for me, dipping to high 30s when sleeping. I've always had a fast recovery to resting too, despite always being moderately overweight. At school the PE teacher didn't believe my figures when we did a test involving measuring resting heart rate, two lengths of the pool as fast as possible, then heart rate every minute until back to resting, as I recovered faster than those who were good racing swimmers. He thought my partner for the test was counting it incorrectly. So it's a bit weird, back then I was endurance fit to do long bike rides or long swims, but couldn't do anything particularly fast, and running was right out, but really good dynamic range and responsiveness on my heart (I assume there's some actual medical term for that).
I find it hard to go over 190 for the last few years; typical peak effort on a ride is now about 185 (I'm mid-50s), whereas a decade ago when I was doing a lot of Audax riding I'd hit 195 on steep climbs - though this was not sustainable for more than very short periods. When I did a VO2 max test as part of a drug metabolism study about 12 years ago, they stopped the test when I was at 210 and they ran out of bags to collect my exhaled breath. The postgrad uni students doing the testing looked quite worried and kept asking if I was OK...
