How can I do a breathing excercise without a preformed technique in the watch? I want to choose my own duration, so a start and stop button just like in the other sports options.
I wish there was a way to track breathing and HR data along with stress using custom breathing exercise, but I doubt it's possible, at least I failed to find the way for that. I think that Garmin may implement it but probably not on VA4...
In fact, I've just submitted request to add that functionality, you can give a try as well, who knows maybe some day it will happen: www.garmin.com/.../
