I have a personal trainer 3x a week, and do some TRX, weights, balance and core strength, and a few other exercises. I would like to get my heart rate during this time, but, seems to be almost impossible to get the watch to allow me to get measurements either continually, or as needed (by pressing the screen or similar). I've tried getting a few apps to help with this, but, none of them seem to do any better than the native app. I can deliberately use the glance to go to the heart icon...then wait...until I get some kind of a reading (which then changes about 10 seconds after it appears, so, doesn't seem like it was being tracked), but, seems I shouldn't have to do that. What I need, is for some way to start it continually reading, so when I raise my wrist to look, I get my current heart rate. This just doesn't seem to much to ask, but, certainly seems to be too much to actually work. What is the best way to make this work right? Do I need to use the native apps, or download one that works better? I'd also like to have it appear on the watch face, so I also have the time, and not JUST the heart rate. Thanks!
