Could someone explain how the watch is capable of telling if my exercise session is aerobic vs anaerobic ?
What is the watch looking at exactly ?
For example, for a 45 minutes rowing machine session where I brought my heart at an average 140, the watch has given me a score of 4.6 in aerobic, and... zero in anaerobic. With a HR of 140 during the session, I would have thought I would get some anaerobic benefit too ?
Thank you.

I am guessing it looks at how much time you spend under or over your lactate threshold heart rate. This threshold is probably over 140 bpm.
When you open the training effect info of an activity, top right button "help" /Anaerobic to read the info you need. Garmin suggest intervals from 10 to 120 sec pushing hard. Read it, maybe that can help…
You can find the help button (question mark) on the web page for Google Connect where you can review your activities.
