Can you go too low? I just checked mine while browsing here and Garmin says it's 33bpm. 35bpm is pretty normal. I've cross referenced my Garmin watch with my hr rate strap and they seem to agree so I don't doubt the accuracy.

I'm not looking for medical advice, just wondering if any of you are in that ballpark and if it's any concern to you,

Wow. That’s crazy low. I’m checking with my elite level buddy, who has to monitor his heart rate with the new Apple Watch (an alarm goes off when it drops below a certain threshold - Dr’s orders). I am also checking with my GF’s neighbour’s brother, who represented Canada in the 2020 Tokyo Olympics. He has run a sub 2:10 marathon. I will report back.

One beat every 2-ish seconds? I would be afraid my heart would get distracted and forget the next one. On the other end, mine is in the 60's last I checked. I'm afraid I'm gonna wear it out. Either way, it can be lowered with training, but from what I've read, mostly genetics.

So much of this is genetics. Even when I'm in crap shape (like now) my resting rate is around 50-52 and when I've been in good shape it's gotten down to the low 40s. 33 does seem crazy low to me, but human variation is amazingly broad.

Do you get dizzy if you stand up quickly, particularly if you are dehydrated? Passing out after standing up quickly is something that seems to happen to those of us with super low resting heart rates.

Yep, not really dizzy though but more like a buzzy sensation. I always crouch low real quick when it happens until everything's right. Haven't ever passed out.

BP can cause this aswell. mGrowing up I have fairly low blood pressure 105/50-ish and I would and still can get a head rush/dizzy when I get up too fast, but my resting heart rate has always been high.

Same issue: Resting is in the low 30s as well. The walk 10 feet then buzz/white out sensation is not all that fun but it's consistent.
Read an article about this the other day but can't find it. The doc in the article said, "when it's below 40 we like to do something about it." But like most things, I'm sure it varies from person to person.

I've never heard of a RHR in the 30s, but I am not a Dr. or an actor. I'm a fit 54 years young and my RHR is 56-58 while sleeping and the low 60s during the day.

Maybe bring it up to your Dr. at your next physical and let them decide if it's something that needs to be checked, especially considering your light headedness when standing.

My resting heartrate is low 40's nowadays, but I definitely have seen high 30's during times of better fitness. And I've always had low blood pressure, so quickly standing up can be lots of fun at times!

I'm more concerned about some of the heart rates I've seen during this cyclocross season than my resting heart rate. I've hit 198 a few times for several minutes during races, and that just kind of freaks me out now that I'm 38. When I first started racing at 29 I didn't care. Now I'm like... ehhhh, this is uncomfortable and screams danger.

I work(ed) with a guy whose HR was in the 30's. He is not even an aerobic athlete. He seems pretty healthy, tho. And I'm told he is uncommonly strong. He just retired 18 months ago.
He might have trouble if his HR went above 100. :LOL:

Can it be too low? Yes. I remember reading about a certain pro roadie who had to sleep with a heart rate monitor, it would alarm if it dropped too low so he could get up and elevate his heart rate. Problem was he was so doped up that his blood was too thick to pump right.

Are you doping like that?

I will occasionally see my heart rate in the high 30's. Garmin's method of determining your RHR is averaging your heart rate while you sleep, so it is always higher than what I might occasionally see when at actual rest. My watch just flashed 46 as I looked, but my RHR last night was 45, but also dropped as low as 44 after I finished my bike commute.

Without any other symptoms, I wouldn't worry about it being too low though.

don't worry about it until you use something more accurate than a garmin to determine next steps

the lower the rate the worse the accuracy in measuring it

My wife's RHR has been 32-36 for decades, the low end when very fit. This has bothered some doctors when they first meet her, but causes no problems and she is healthy as a horse. She's one of the most genetically gifted endurance athletes I've met (also a hard worker).

I've never heard her mention the dizzyness issue; mind you, she is very short so her head and other appendages aren't far from her heart. :)

I've had the dizzyness issue, but from low BP. My RHR has been as low as 48, but now (fat) about 58.

I've seen as low as 40 beats per minute, when I'm getting after it for months like I should. I had chest pains after catching covid that wouldn't go away, thought I might have had pneumonia, went to a walk in clinic for a chest x-ray just to rule it out, got an ekg, and was told to go to the emergency room because of "abnormlities".

After three hours and all sorts of imaging, I got a bill of pleuritis. The whole time I was hooked up to the machines I kept setting off alarms because my heart would drop to 40 beats per minute. I'm guessing their equipment was pretty accurate. They weren't worried because I told them I had ridden my bikes for thousands of miles that year, so 40 must be fine for people in the right kind of shape.

I get the fuzzy light headed near blackout thing sometimes if I stand up quickly, but that's usually after crouching for a while when you block off most of your veinous reurn and then open it up suddenly. Baroreceptors think your blood pressure is spiking when it isn't and they drop your blood pressure. I get that whole thing quite often, but not without crouching.

My blood pressure actually runs high. I'm around 145/80 most times, but I drive a truck all day, and nobody on the road knows how to drive..........
