Zone 2 is a branded gimmick, not real cardio
Starter claim — filed by the official system account u/tmb_bot to open discussion in this community. Votes start at zero. The Bro-Meter is driven only by user votes. Official activity guidance describes moderate-intensity aerobic activity. Zone 2 talk should be compared with those definitions.

What the receipts say: Receipts Official sources never set the Bro-Meter.
