Active minutes

[joemcw]

I can't reconcile my 100 active minutes, total for the day, with my 2 hour yoga practice which indicated 509 cals burned and heart rate measured at 15 mins peak, 53 mins cardio and 47 mins fat burn. Doesn't yoga practice alone add up to more than 100 active mins?

Hello @joemcw and welcome to our Fitbit Community. Note that I don't believe that only your Yoga exercise have gave you active minutes. If you are very active throughout the day its possible though. Your tracker detect subtle differences in exertion that may explain why two seemingly identical activities result in different active minute totals. Essentially active minutes are a measurement of time spent doing activity that is more intense than regular walking. Trackers with a heart rate monitor detect active minutes most accurately, since heart rate data allows us to better estimate caloric burn and, in turn, exercise intensity.

Hope this helps and see ya around.

Thank you for your reply to my query regarding Active Minutes and how they are counted.
Most people do not understand the intensity of my yoga practice.
I do the practice almost every day for a period of 2 hours.
My Surge device indicates a sustained heart rate average of 104-112 beats per minute. Typically the heart rate for my body is one hour in fat burn, 45-55 minutes in cardio and 5-12 minutes in peak. In addition I have a calorie burn ranging from 4-7 per minute, average.
If you understand physiology, that is pretty intense.
With this new understanding, please review my initial question and redo your reply.
Thank you,
Joe McWilliams

Hi there @joemcw and thank you for the details. I was reviewing your post along with my reply and I want to offer you an apology for it. It sounds kinda rude but it was not my intention. I was referring that active minutes it will not be equivalent to your total time of the exercise. I do understand you, yoga can be pretty intense. 

In this case note that active minute are earned according to the most intense time you do an exercise. On your post you mentioned that reach 15 minutes peak so this time is the one that it counts for active minutes. 

Your tracker will calculate active minutes using metabolic equivalents called METs. METs help measure the energy expenditure of various exercises in a comparable way among persons of different weights, METs are widely used as indicators for exercise intensity.

MET of 1 indicates a body at rest. Fitbit trackers estimate your MET value in any given minute by calculating the intensity of your activity. You earn active minutes for activities at or above about 3 METs. Minutes are only awarded after 10 minutes of continuous moderate-to-intense activity.

See you around and let me know if you have more questions.
