I'll add to the anecdotes here: I lost 90 lbs and got fit over the past five years, and my Fitbit played an important role in that. Initially, it was helpful for me to be aware of my overall physical activity. Weight loss is mostly diet, but I didn't have a clue about my average steps or my heart rate during exercise. I got to watch my resting heart rate drop from the 70s down to the 40s as I picked up cycling, hiking, and regular walks. When I began weightlifting and other more strenuous training, I then understood my heart rate zones and could track my progress. Gaining a deeper understanding of my body and seeing progress over time was very motivating. Definitely a big positive for me.
