Hi all!
I recently purchased a Garmin Fenix 6x Pro, and couldn't be happier.
I do however have a burning question - how do I track a High Intensity Interval Training? I saw a couple of suggestions that I should use the Cardio workout for this, but it doesn't seem right as the calorie count is way off.
So far I have been using a Polar H10 with the Polar Beat app and I have a pretty descent baseline of the usual calorie count. I had used the same HR monitor and app with gym equipment in the past and the calorie counts have been consistent (between the calculated from the app and the equipment when both are connected to the same HR).
So, when I got the watch I did my usual workout with the OHR only for the watch and the usual HR monitor with Beat app combo. The app showed the usual amount, but the watch was about 17% below. The next day I connected the H10 to the watch via ANT+ and at the same time to my phone and the Polar Beat app via Bluetooth. As expected, the watch had perfect reception and the HR was the same between the watch and the phone.
And here is where it gets interesting - while I was keeping the intervals at about 2 minutes (1m effort and 1m cool down) both calorie counts were about the same (+/- 3). However, the moment I started doing intervals shorter than 1 minute (30s effort and about 30s cool down), the watch started dropping hard. In the end the difference was about 13%. I attribute the 4% difference from the first try due to the different measurement devices, so this doesn't bother me.
But I wonder where the difference comes from - is it the different algorithms? Or maybe I should track using a different activity profile?
Any help will be appreciated!
