It's called bradycardia, and I have it too, I'm in the 40s when I wake up also. As long as you don't have symptoms such as shortness of breath, dizziness, etc., and as you say you're athletic, it's normal. Athletes can even be in the 30s without problems though this is supposed to be exceptionally rare.

(I'm a bit of an oddity because I got mine from strength training alone, not cardio, which isn't supposed to happen. But I am naturally slightly bradycardic - even when I was 245 lbs, I had 58 bpm w/ zero exercise.)

Yes, I check it fairly regularly before I get out of bed in the morning.

I do have a physical booked for Tuesday because my doctor wants to do a full assessment after my weight loss.

Thank you for the replies.

50's is perfectly normal for someone who works out regularly.

Achieving mid 40's typically requires people to work out regularly with some intensity. "Fitness enthusiast" may well achieve this level, without necessarily pushing yourself to 'professional athlete' levels.

My guess is that your RHR is "lower than average, but still within the normal range for someone of your fitness". Remembering of course that 50% of the population are "below average".

But if you are concerned about it, you may want to speak to your doctor - he would have a better idea of acceptable ranges. Mid 40's can indicate a problem, or it can just be a sign of a good level of fitness.

When are you measuring your resting heart rate? Are you doing it first thing in the morning before you do any movement whatsoever?

It is not uncommon for one to have a low resting heart rate once they become active (mine is in the low 50s). The reason, exercise makes your heart stronger so that with each beat it is able to pump more blood with more force through the vein in a relatively short period of time. As long as you are not experiencing any other symptoms, you should be fine. You may just want to run this by your doctor the next time you see him/her!

Ok to ask for other's experience but i think a medical professional would be best equipped to answer your question

Before starting cardio 8 months ago, my resting heart rate was around 70-80 bpm. Within 3 months of consistent cardio it dropped to 60 bmp and stayed around there until the last 2 months. 2 months ago it was at 50 bpm. Now it's in the mid 40's. Is there any reason to be concerned? My blood pressure is also really low. It's always been on the low normal side but I checked it a month or so ago and it was in the range of professional athletes and kids, I'm of course... neither of those.
