How many calories did I burn while… ?

Unfortunately, any answer to this question can only be an estimate at best, and it is not wise to trust any number to be 100% accurate. In particular, you should absolutely not rely on exercise machines themselves (such as treadmills) or wearable fitness gadgets to give you correct information about calorie burn.

However, there are a few reference lists that can be used as a rough general estimate:

  1. Harvard Health
  2. Mayo Clinic
