Just reading through these posts and I wonder if all of you realise that you should take your resting heart rate when you are lying down, completely inactive.

If you read your resting heart when you are sitting, it is not your resting heart rate, it is your sitting heart rate. Your body is working at keeping itself balanced and upright.

Some people wear their HR monitors when they are sleeping and read the lowest setting form the whole night when they wake. Mine doesn't do that, so I just lay completely still on the floor in the living room and got one of my sons to watch my HR. I've redone it several times and got the same reading each time, or a beat above.

Have fun finding your resting, resting HRs
