I have Garmin F45. I'm about to try Zone 2 training but unfortunately my HR Zone is slightly miss from it's right range number, so I have to configure it myself. But when I tried to find the menu, I couldn't find it both in my phone or web, eventho it's said in the manual book that there's menu to configure your HR Zone.
Is anyone experienced the same? Please help me set up my HR Zone in Garmin Connect.
Thank you very much.
