    Is anybody having problems with losing your heart rate some time during exercise? About half way through every run or other high intensity workout, I lose my heart rate, and it does eventually come back. I was wondering if it is caused by sweat.

    Sounds like a working hypothesis. Perhaps you can test it by pausing your workout, wiping your wrist, reauthenticating when you put it back on your wrist, and letting us know.

    Maybe then, it the hair on my arm, or maybe I need to drop down a band size? I will first wipe my a off to see if that's it. Thanks.

    If you think it might be the hair on your arm, try wearing the watch with the body on the inside of the wrist where there is typically less hair.

    That's a good tip! Before I saw this tip, I actually shaved the hair off the spot where the watch sits. It worked, never lost the HB once 😁

    I believe the Apple Watch is only supposed to be worn on the top of the wrist.

    No issues here. Could be the watch is too loose. I tighten it during workouts - kind of hurts, as my wrist expands during exercise, but it grabs a solid pulse.

    Yea, since I started running a week ago, I have lost weight and am on the last hole on the large band. Might have to put the small one on.

    I've used it several times with no issues. Today I did an extra intense workout and noticed it was having trouble with reading the HR. When it came back it was in the 50s and 60s for a couple of minutes before finally going back to an appropriate rate. I don't have really any hair on my arms but I was really sweaty. My watch was as snug as it could be.

    Yea, that's kind of disconcerting. Fingers crossed, since I shaved the part of my arm where the watch sits, it hasn't skipped a beat (no pun intended)

    I have a follow up to my initial report, and can now join the group of concerned owners. Today, during my P90X workout, the heart rate struggled to get a heart rate, and showed my rate in the 60s when I was clearly well into the 150s and beyond. It was during Cardio X. Seems when I moved my watch back further on my arm, and further from the end of my wrist, the heart rate jumped back. I do have arm hair - not too hairy, but normal dude hair. That concerns me. I'm certainly not going to shave that part of my arm. I'm wondering if it's sweat-related, or hair-related. Anyone else venture a guess?

    In my case it had to be sweat as I have almost no arm hair at all.

    As an update, I've used the watch for several heavy lifting and yoga sessions (30-45 minutes) without issue.

    From what I've heard from people with fit it's, is that theirs does the same thing now and then.

    I don't have an Apple Watch yet, but I have this problem frequently with my Mio watch, which uses similar technology. Have to really tighten the band, but I still get rapid negative spikes (from 120 to 80 for example). From what I read, the Apple Watch has similar problems but a lot less frequently. Looking forward to trying it out soon!

    I have the same problem. I am a lady (very little arm hair). I do aerobic activity and circuit training in the gym a lot. I noticed a huge decrease in my heart rate on the apple watch when I start to sweat a lot. I wipe under the watch face to see if that helps. It usually brings the heart rate back to normal. However, I'm sure it has by that time thrown my calorie count off.
