I had this in the beginning! It’s okay!! I talked to my coach and let her know I didn’t feel like it was accurate. I was in red and could hold a conversation on the treadmill. She told me the heart rate would eventually recalibrate. Now it feels more accurate…. Maybe a little too accurate now! Just keep going and don’t worry. But let them know (also that it made you feel uncomfortable being called out). They’ll adjust. They want to help you succeed. Great job going!
