Long Long time a go, I use my garmin device with Windows based app where every workout must load by cabel. It was Firstbeat app..
In that app was both training effect (anaero & aero).
And in same workout diagram was HR curve was own curve for TE where yuo can see that point in workout where the highest value was reached (it was not all time at yhe end of workout).
Why this curve is not in garminconnect?
