Fitness trackers: are they any good for tracking calories? are they worth the money?

>are they any good for tracking calories?
No, they're not.
Reasons why: heart rate and 'steps' are not enough information to *accurately* determine calories burned. Such devices use a formula based on a number of assumptions based on statistical averages of a large population of people with levels of fitness varying from sedentary to moderately physically fit. This yields a range of calories burned for various levels of activity. Devices like these, like stationary bikes and treadmills at a gym, will tend towards the high end of these ranges to keep you motivated. As such you cannot use them in any meaningful way.

Only devices that directly measure work output, like a rowing machine ergometer, or the various torque-and-rotation measuring devices for bicycles (PowerTap hubs, SRM and Quarq cranksets, various makes of power-measuring pedal sets) can be considered anything close to accurate, because they provide you with kilojoules generated, which can be converted to kilocalories, which within 5-10% can be used as an estimate of kilocalories burned to generate that work-energy.

So-called 'fitness bands' only serve as fake motivation. They also provide a way for the manufacturer to gather personal data on you, your habits, and your whereabouts, which they sell to advertisers, who use it to target ads directly at you. May also be sold to healthcare companies, insurance companies, and be subpoenaed by law enforcement, since it contains GPS location data.

Summary:
* They're inaccurate junk, a waste of money
* They invade your privacy
* You're better off just using tables and calculators online to determine estimates of calories burned

I don't know how paranoid you'd have to be to think a watch is invading your privacy. The watch is synced directly to your phone. By applying your own logic I shouldn't have a phone on me either.

>I shouldn't have a phone on me either.
Not a smartphone anyway

>The watch is synced directly to your phone.
..which has GPS
..which is connected to the company servers via the app you have to load on your phone
..which transmits all the data the band collects, plus your GPS location data
..which is all collected and sold by the company

Try reading through every single word of the 'privacy agreement' you consented to when you started using this thing, and when you loaded the app necessary for it to function at all, and you'll see that you've been giving away data to this company from the moment you put it on, and there's no way to use the thing without that happening. It exists to collect marketing data on you. Why do you think the military prohibits their personnel from using these? Because they're tracking devices.

You don't need these at all, they're garbage anyway. Just keep track of your own shit and use online calculators and tables if you're so concerned about how many calories you burn walking or whatever. It's not even very important, it's more important that you eat less and just move more if you're fat and want to lose weight. Stop over-thinking things and just do it, save your money, don't waste it on stupid shit that cucks you.

ALL of this has been proven to be true over and over again. You're late to the party.

Okay, Dale Gribble.

neither do i, mine is at 55
You have heart issues

You dumb faggots can scoff all you want but the FACT of the matter is that these ridiculous 'fitness trackers' are inaccurate garbage and a waste of money, they're a MEME, and you're stupid if you buy and use one, regardless of whether you believe or give a shit whether you're being tracked like a cuck. FFS if you want to know what your goddamned heart rate is then get a real heart rate monitor and stop fucking around with this stupid meme shit. How dumb are you people? Sick to death of stupid people doing stupid shit. Fuck you, do what you want dumb cucks. *rage quit*

I have that do. My father's blood pressure is awful and my grandfather had 3 heart attacks by 60.

OP realated picture is Charge 2, not water resistant, Charge 3 is.

I got a Charge 3 recently, I don't really make decisions on the data it collect, but I kinda like to check it.

Worst thing about Fitbit is the synchronization. It only synchronise with it app, and need Internet connection. Also have a few devices (phones and tablets) with compatibility, the other will give problems.

fyi I would mostly use it to bulk because that's what I'm doing right now

Not that user, but I have a charge 2 and it is water resistant.

Not only based, but redpilled as well.
