    can anyone tell me if the series 2 watch shows pulse rates quickly.
    So I am at the gym with Workout on via the app Heartwwatch.
    I raise AW and it shows my pulse rate at 80bpm after a set of chest presses.
    That is wrong. That is what it was some minutes ago. It should be about 110.
    I wait and eventually the bpm inceases a bit.
    I know this because i did use a polar monitor with chest strap before AW.
    Knowing what my heart is doing quickly is important to me because I am 80.
    I want to know bpm quickly. Does AW do this ?
    If not I must go back to Polar.

    i know normally it does a heart rate check every 5 mins
    i don't know if you're in a work out if it checks it faster or not
    polar is checking it all the time so its not a equal comparison

    I am pretty sure that it continually checks your heart rate when in a work out mode. I run in the am & walk the dog at night & I use the respective work out options, so when I raise my wrist I get a live read of my HR. I also lifted my my watch on my wrist a tad to see the green lights were on the first two work outs I did, enabling constant reads.

    Indeed it does check your heart rate when you're in workout mode regularly.

    I have the same issue. I set it to a workout mode (just general, as I'm doing weight and cardio training...and that's not an option (NOTE TO APPLE: This SHOULD be an option!)), and it's ALWAYS way behind on my heart rate. I have to pause and wait, sometimes almost a minute, until it reads right finally.

    I purchased a few hear rate monitoring apps...and they do the same thing, this is "working as designed"?

    Optical can't accurately read constricted tissue like when lifting weights. While HR is not directly correlated to anaerobic workouts (no meaningful info unless you have a medical condition), if you want a more accurate and timely reading you will need to pair a BT HR strap.

    Thanks all. I found my old Polar with chest strap. Next trip to gym I will wear both Polar and AW, and see how they compare.
    I was hoping to get away from strap but maybe not so.
    With both on I am going to look like a wierdo.

    When weight training I only wear my :apple:Watch (since HR is irrelevant) but when doing cardio machine, running or biking I also wear my Garmin 620. While it may seem like you look weird to others in reality others are paying you as little attention as you are playing them.

    Wait... if you're at the gym, how can other people see your chest strap?

    Unless your gym allows people to go shirtless?

    You can also pair the Polar with the watch and use the Polar readouts for the display under Workouts. That's what I do when working out.
