Hi! I did a workout today, a treadmill-based workout that I do at least once or twice a week. I examined the data afterwards and despite my heart rate following an almost identical pattern to what I did last time I completed this workout, my watch recorded around 100-130 fewer calories. This workout usually gives me a calorie burn of 330-350 calories and today’s was 198- a lot lower. Can anyone shed any light or has anyone observed something similar?
