Heart rate during workout

I have noticed in past couple of days that my watch 5 hasn’t been showing heart rate for quite sometime during walk and running workouts. It remains grey for more than 5 minutes, on and off for sometime and then it starts showing continuously. However, upon checking the heart rate graph on fitness app on phone post workout, the graph picks up only where it actually becomes visible on the watch during workout, that is well after five minutes of the start. Even as minimum and maximum rate is registered, I am sure this messes up average heart rate as well as subsequent calculations such as VO2Max.

I have already tried resetting the watch. And as I said, the heart rate does show consistently but only after a long time lag. However, other workouts such as Pilates or strength training regularly show heart rate unhindered right from the start!

Apple Watch Series 5, watchOS 8

I tried all kind of things, but none was solving the problem in a consistent way. Some runs it was OK, during other run the same problem happened again:

replaced the iwatch 4 by an iwatch 6
I also adjusted the band tighter
I activated the heartbeat app, waited until I saw the heartbeat appearing before I started the workout app
running without iphone, running with iphone

nothing seems to help!

Tightening the band slightly worked for me for running workouts.

The article you sent the link to was related to heart rate recording. My problem is different. It does record it but doesn’t show the ongoing heart rate for about first 5-8 minutes of a walking or running workout. After that it’s constantly showing the rate. It started to happen in last one week only. Picture enclosed:

Hi. Yes, your issue was understood from the outset. The article covers this issue and suggests that one possible solution is to adjust the band to fit more snuggly on the wrist. Could you confirm that you have tried a more snug fit? This could then be eliminated as a source of the issue.

Yes. I use original steel band for running and adjust it a couple of times if lose. It fits very well.
