When I take my watch off I usually turn the heart rate function off to save battery. Sometimes I forget to turn it back on when I put the watch back on. It really bugs me when I start a workout, only to realize some ways through that I had forgotten this. From what I can tell, the only way to get a heart rate reading on my workout would now be to stop the workout, turn the function on, then start again. I'd really like to see the ability to turn off/on heart rate while a workout is going because I don't want to split my workouts when it's really one.
