Activity trackers are talked about everywhere; go out running and half the people you pass will be closely examining their wrists/smartphones to see how may steps they've taken, how far they've gone and - this is the dangerous one - how many calories they're worked. I know this. I'm one of those.
They've been written about in the
New York Times and the B
ritish Times because everyone's been jumping on the activity tracking bandwagon, and there are no end of reviews of the
'best' activity trackers on the market, with new ones being launched all the time. Take your pick.
I don't use them for calorie counting because I agree with today's Times that that can become a dangerous habit, and pretty useless if you count carbs, not calories, and I definitely don't sleep with mine. I use my Fitbit One to tell me how active I've been, and to motivate me to do more, and it works.
I currently use two (I know) - the
Argus activity tracker which is only available on iOS and the
Fitbit One and I find both useful and enjoyable. Because I want to be fitter and more active. They tell me the same things in different ways and both have added benefits. And yes from the point of view of motivation in my opinion they work, but they'll only do so if you want to be fit in the first place.
Here’s the run down on Fitbit One and Argus, I particularly like the Fitbit One because you can clip it to a piece of clothing and don't have to wear it on your wrist.
