Why is my total calories burned reading so low on Apple Watch?

I have noticed that around every other day my total calories burned is very low. I workout everyday and my move goal will be completed but I feel like it’s not accurately tracking my daily movement. Some days will be normal and then others are low. Now sure how to fix this. I have tried updating and restarting my phone and my watch with no luck.
