My wife received her watch a couple of weeks ago. In that time, beyond giving me hell because mine hasn't arrived yet, she has been using the watch to track her fitness activities such as indoor walking, elliptical, strength training, indoor cycling, outdoor walking, etc. The other day she asked me what she needs to do to see her heart rate while she is exercising. I told her that once the activity tracking has started for whatever category she has chosen, she can swipe left or right along the bottom half of the display to change the metric that is displayed including heart rate, calories, etc. She told me this morning that there was no way to view the heart rate while exercising, and I told her that there is (and re-explained how to swipe to display the metric she wants to see). Turns out that we were both right (or wrong, depending on your perspective). For elliptical, cycling, and other (as I recall), the heart rate can be shown during the exercise. For anything related to walking or running (indoor or outdoor), however, the heart rate can not be shown. Is this consistent with what others are finding? Anyone have a guess as to why heart rate can not be shown for anything related to walking or running but can for the other exercise tracking options?
