HR Based Interval Training = Out of range alert spam

HR Based Interval Training is a bad experience and doesn't work properly because of the annoying out of target range alerts.

And this is with Garmin's suggested daily workouts.

Example: a threshold interval (+- 167bpm) followed by a rest interval (+-129bpm). After the transition, obviously the heart will take some time do slow down. But rhe watch will start spamming "OUT OF TARGET HR" alerts right away!

There should be a delay or a predictive algorithm to avoid this.

Ps. The same happens with speed/pace based intervals because of the GPS delay, but the time frame is smaller.

HR isn’t a great choice for intervals. It responds much too slowly.

HR works well for longer tempo-type sessions and easy runs - anything that is mostly steady-state for longer periods of time.

Pace or power are better choices for short intervals (or just straight time if you’re on a track where you can compare your splits against your expected times).

For long intervals, like 10min, it would be fine to use HR. They only have to make it wait for a some time to adjust the HR before giving alerts like "too high" or "too low".
