Is there a device that is waterproof and also tracks heart rate all day?
I am curious if there is a device - Fitbit, Garmin, or one of the many others.. that will track my heart rate and calories burned all day, even if I am sitting still, as well as be waterproof for swimming laps? There are so many options I don't know how to sift through them all without taking up hours... Thanks for your…
