Heart rate not getting above 150.

Ok so I am 45 years of age and I am in pretty good shape.

My main go to cardio is skipping with weighted crossrope skipping ropes. So my issue is I'm trying to the point where my lungs are literally giving out but my heart rate is may be getting into the 150 range for a minute at most of my workout. Now there is a chance that my heart is in much better shape than my lungs but that would be very random. So my question is is anyone else middle-aged having any issues with their phoenix f6 recording their heart rate at higher levels or or is it a problem with my lungs not keeping up with my heart??

I am essentially training like an absolute demon anyone that has tried skipping or no what kind of cardio it is and how hard I try it's just constantly saying I am maintaining my fitness and I'm getting into 150 plus bom for no more than a minute of a 35 minute workout.

But appreciate any advice people can give, thank you.

I've been having the same issue on all activities, save Cardio, since August 2022. In my case the issue started with my HR never rising past 100 or so on the Treadmill activity. I have not found any solution and have had this issue replicated across 3 devices. I ended up being gifted an HRM strap which I am now using instead but I hate that the only thing I could do was potentially buy an expensive, additional piece of equipment.

I've written about my problem and all the steps taken in detail here: https://forums.garmin.com/outdoor-recreation/outdoor-recreation/f/fenix-6-series/314591/heart-rate-completely-inaccurate-during-workout--fenix-6x-pro-solar

Thank you for replying it's good to know I'm not the only one it's only been the past couple of months as always work great before so I don't know if it's been an update issue or what but it is very frustrating.

try to put the watch band 1 hole shorter on your arm to get better fit. It might help. But it won't be 100%. As SourCherry wrote the ultimate solution is to use a chest bases HRM.

I've owned my Fenix 6 since the summer of 2020 and have seen numerous threads like this regarding "it used to work before firmware update xxx". Seeing that early on, I've locked down my firmware to something like 9.0 and turned off the auto-update feature. That doesn't help you fix your current problem, but just an idea for if they ever release a firmware fix then you could lock yours down and avoid these kinds of issues in the future.

In my case everything I needed worked at that time, so I figured why risk a firmware update induced failure if it wasn't fixing anything I actually cared about.

Thanks for the tip.

I didn't even know you could do that, thank you.

This "it was working in version X, but stopped working in X+1" usually helps to find the cause of the problem, when you as a developer who changed it get this information. So it probably is useful for Garmin, assuming they care...

If you're gripping and flexing the wrist and getting poor results my advice would be to get a chest strap.
