Three years ago, I used 3 Garmin watches for a small research project. (vivoactive 4, vivosmart 4 and forunner 30). They were worn simultaneously for one week by 4 people. I want to know how to extract this data as easily and simply as possible. I can do it manually by logging into each profile and then copying the activity, stress, sleep, etc. data. Is there a simpler way to do this, perhaps through Strava or another program?
