Apple watch 6 and calorie burning

Does anyone else find that their calorie burning count and exercise minutes is seriously under calculated? Is there a fix foe this? After a 45 minute CrossFit class, it shows only 10 minutes of exercise and 230 calories burned? Wth? My previous Apple watch, a series 4, seemed to over calculate calories. Sometimes I would burn 3200 calories in a day. Now I cannot even get to 700 with a CrossFit class!

See the "Make sure that you earn Move and Exercise credit" section in:

You should also make sure your watch is calibrated:

According to What is the difference in "active cal… - Apple Community

Total calories include - basal calories + calories burned when doing a workout. Active calories are those that are burned during some activity like swimming running or anything else where your body is moving, Basal are those that your body burns during a day without any activity.


Based on what I have read in the replies to Workouts Not Recorded by Exercise Ring - Apple Community, unless you use "Other" or "Yoga" you have to accomplish at least one of the following for a "minute of exercise" to be counted as an "exercise minute":

  1. Heart rate higher than 130
  2. Average pace lower than 18'10" per mile
  3. Speed higher than 9.5 mph


I have also heard that according to Apple Support, for the activity ring to register your workout (for outdoor walk on exercise ring) you need to maintain a speed of approximately 3.3 mph or faster and increase your heart rate to approximately 75% of your High Heart Rate (from the iPhone Watch > Heart app). This definition of a "brisk walk" is to encourage you to put more effort into the walk, (For an Outdoor Cycle its is 9.8 MPH (or 16 KPH) and 75% of your High Heart Rate.) If you slow down or pause, the watch will stop giving you exercise credit, It will still measure your steps and calories burnt but will not give you any credit towards the exercise ring or workout app. A brisk walk speed is different for everybody as the watch takes into account your age, sex, weight, and heart rate which is why it is important to calibrate the watch and have the correct details set up in the Health app,
