Based on your estimation, the device estimates the kcal consumption and
adjusts your exercise plan and history accordingly.
NOTE: Follow your personal feeling during the exercise when estimating your
exercise effort.
You can view the following information in the summary:
● starting time and date of the exercise
● percentage of completion
● duration of the exercise
● estimated amount of calories burned
TIP: You can use the estimation feature in sports where you cannot record
your HR or use your HR belt, for example swimming.
