Defective heart rate monitor??
This is the heart rate reading I get from my watch during my morning workout. The watch is 3 weeks old - is it defective or is this how some readings turn out??
Thanks for the reply, but I already tried tightening the watch. I can see why the gaps in detection would point to the watch not being tight enough, but would that cause it to read a varying rate of 44-133 beats per minute during a 60 second interval in the middle of an hour workout as it shows at the 7:40 mark?
