I have noticed that since getting the sense that my weight workouts do not appear to be working appropriately. I am burning clearly less calories and it is very difficult to get my heart rate into the fat burning stage or cardio stage during weights. This was not the case with my versa special edition. I have watched comparison videos between fitbit sense and various heart rate monitors and it appears that the fitbit has issues with lag when doing things like weights, when heart rate will go up fast and in bursts. It showed that the heart rate struggles with lag during climb but not during decline in heart rate. Whats going on is this something that can be updated with the next update.
