zero active minutes for cycling?!

[juhendo]

Some of my bike rides get zero active minutes when heart rate is 100 and speed is >20km/h. I have a heavy pack on with a heavy bike. Feels pretty hard!?

It's great to see you around the Community @juhendo ! As you may know, all Fitbit trackers calculate active minutes using metabolic equivalents (METs). METs help measure the energy expenditure of various activities. Because they do so in a comparable way among persons of different weights, METs are widely used as indicators for exercise intensity. For example, a 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.  To stay in line with the Center for Disease Control's (CDC’s) “10 minutes at a time is fine” concept, minutes are only awarded after 10 minutes of continuous moderate-to-intense activity. You can view the CDC’s recommendations on the CDC website.

If an activity gives you active minutes one day and fewer active minutes the next day, remember that the intensity of exercise is key. Often what seems like the exact same amount of effort over the same distance in fact differs slightly enough to change your active minutes total.

By default, you are given a starting goal of 30 active minutes a day based on the CDC recommendation of 20-30 minutes of daily moderate-to-intense activity. You can always change your active minutes goal to meet your personal needs.

Trackers with heart-rate sensing do a better job of recognizing active minutes for non-step-based activities, such as weight lifting, strenuous yoga, and rowing. If your tracker doesn't have heart-rate sensing, your active minutes will be lower for non-step based activities.

Happy stepping!
