Extremely low and inaccurate caloric expenditure calculated by Garmin forerunner 35

Garmin forerunner 35 does not accurately calculate caloric expenditure during activity. I’ll spend 47 minutes in fairly high intensity Circuit training, yet the device will calculate my caloric expenditure for that activity as 135. This is been a consistent problem regardless of activity type since I purchased the watch. Any advice on how to get an accurate measurement?

My garmin has said I've burned 350 calories on my past three eight mile runs... I feel like this is inaccurate.

I think this has something to do with your weight, height and heartrate. I assume you measure your rate on your wrist. This can't be measured exactly. When your Forerunner thinks, that your heart rate is high (or low), the calories are calculated wrong.

Maybe, a heart rate monitor for your chest helps with this problem. But I can't guarantee anything.
