I just exercised for 43 minutes and my watch only says 2 minutes. Why?

To earn 1 minute of exercise credit(green ring);

Travel a full minute at a brisk walking pace(3.3 mph approx) or above.

Raise your heart rate to approx 75% of your maximum.

When you're at around or above this heart rate and speed for the entire

minute you'll receive 1 exercise minute credit.

If you pause or slow down during this minute then you won't get any

exercise credit for that minute.
