I've been reading the posts about the apple watch is way off with calories burned and I'm finding this true as well. I've compared 3 different watch brands with chest straps and in the lab and the watch seems to be at least 40-50% lower that what I'm doing.
Also when I completed a 25 HIIT training workout the heart rate wouldn't record because of fast arm movements with ropes sledge hammers, KB swings etc.
thanks,

Hi
When comparing data between apps, keep in mind that Apple Watch reports active energy / calories, whereas many other fitness apps report total energy (resting + active calories).
To help improve the accuracy of calorie estimations (and other activity-related estimations) made by Apple Watch, you can calibrate your watch. Calibration teaches your watch how your arm movements relate to your stride lengths at different speeds when you are walking and/or running. It does this - during outdoor walks and/or outdoor runs - by comparing data from the accelerometer with GPS (Location Services) data from your iPhone.
It may help to reset your calibration data and start afresh:
On your iPhone, in the Watch app, go to: My Watch (tab) > Privacy > Motion & Fitness > tap on Reset Calibration Data.
To calibrate your watch, follow the instructions in the support article below, including:
Activity estimations made by Apple Watch also depend on your personal information. To check that this has been entered accurately and to update it over time:
- On your iPhone, in the Watch app, go to: My Watch > Health > Edit (upper-right).
The heart rate sensor (data from which may be used when estimating calories) is likely to give better results for workouts that involve rhythmic (eg running) rather than irregular movements (eg HIIT). If you find that you are unable to achieve consistent readings during HIIT workouts, you may wish to consider pairing an external heart rate monitor / Bluetooth chest strap to your watch.
