Is a resting heart rate of 31 a problem ?

[Bestseller]

I wear a HRM to monitor my fitness and recovery. My resting heart rate is typically 50-55bpm, increasing to 60ish the day after a hard training session.

Today it's been less than 40 all day and now 31. Which is off the scale, apparently the fittest athletes are around 40!

Does it matter, or is it only an issue if it drops to 0?

Fwiw I've felt dreadful all day, not ill exactly but like all I want in the world is to lay down.

Won’t I am so sorry for your loss. It is never what we expect that comes for us.
Our family’s been shattered by this. We’re slowly rebuilding and trying to gather some sense of normality around us but it is very fragile.

Thank you to others for your kind thoughts and words.
I just hope OP has taken action.

did you ever find out anything, @Bestseller ?
