I recently added rowing machine to my cardio but very confused by how much calories it burns based on my Apple Watch estimate 😅. I know it’s not very accurate but still want to understand the reason behind it and if there is a better way to estimate it.

Two examples from recent two sessions:

1. One hour rowing, avg HR 144. 345 calories.
2. One hour walking on treadmill with incline, avg HR 112. 329 calories.

Obviously rowing was a lot harder with much higher HR. But how come the estimated calories are the same… When apple does the estimation they should use all these metrics, I would anticipate there should be a difference but maybe I’m missing something? Thank you for any tips you might have!
