Did anyone else happen to see last nights's episode of "Trust Me, I'm a Doctor" on quite late - on BBC2 so easily missed!
They were reviewing wearable fitness monitors - most looked like fitbits to me! Seems the heart rate monitor readings (based mostly on wrist pulse) are pretty unreliable. And the step counters aren't a whole lot better!
I assume my Garmin Chest strap works on vibrations, since when I wear a flappy shirt or don't do it up tight enough I get Very Odd readings indeed!

Daz LoveI had read that the HR on fitbits can be out. I do use one and really just you as a gimmick. I don't get the impression they were designed for already active people! 10k steps a day, the amount I do playing golf and running each week is c17k per day on average!!
I always thoug the chest strap HR from Garmin (which I also use) picked up actual heartbeat it's not done on vibrations. I can tell you that when working hard eg interval training the HR between Garmin and Fitbit is out by a fair bit. When resting there is little difference.
From what I have read the HR straps are as accurate as you can get. Yes, if it slips you get a misread as is not in the right place!
