Couldn't agree more on this. Just another technology trying to justify its reason for existing. I personally use an 'old fashioned' heartrate monitor(cost around $20) from time to time just track the peak decline as I age, but it's hardly a necessity. IMO Fitbit and similar tech can give a false sense of conditioning. Aerobics are vastly overrated anyway, high intensity interval training(HIIT) and resistance training are where it's at as far as total body conditioning and trackers are pretty useless there.
