My first post--please be gentle : ) Brief background--I am using the 42 MM SS AW BSB as a watch and as a replacement for my fitbit flex. So the fitness/activity aspects are important to me. 1. I don't really feel like I understand what I am doing when I am setting my goal in the Activity App. I have set it for 500 calories. But what does that really mean? I have no reference point for that. Is that good? Will I lose weight? Every day I am hitting nearly double that. What about setting step goals? Distance goals? Flights of stairs goals? Why is setting a calorie burn goal useful? Am I over thinking this? How do you know what would be a good goal to set for yourself? Is there any credible information on this or do you just guess what the number should be? 2. The day before my AW arrived, I bought the TICKR heart rate monitor chest strap. I used it on a run with the chest strap connected via BT to my iPhone 6 Plus not the AW. Outdoor run was selected in the Workout App on AW. On this run AW said total cals (rest + active) were 539 with 157 Avg BPM. The TICKR gave total cals at 663 with 149 Avg BPM. Today, I did Crossfit and our workout was all cardio. I used the TICKR connected via BT to the AW. I liked how I had quick access to my HR. Even though I have done similar workouts this week with just the AW--no chest strap--my total calories today seemed significantly higher (200) than when I have done similar workouts with just the AW and the Workout App set to Other. My question is---is the chest strap overkill? I keep reading these pieces online about how accurate the HR monitor is on the AW, but my feeling is I am getting more accuracy with the chest strap. Any thoughts on this? Obviously, I would rather not wear a chest strap. And the TICKR App does know my age, gender, and weight.
