Don't forget that they cant really track how many calories you burn off doing strength training because the relationship between heart rate and calorie expenditure is different from that of doing cardio. So it will in the case of strength training overestimate how many calories you actually burn.
Has there always been this many stock photos?
yes... lol
I mean, they normally have a bunch of Luke with green screen effects in his back with a few stock photos... The entire video is stock photos lel
Dennis is the one usually editing the quicky videos. i guess that is his style :)
How do fitness trackers work?
"They have many components similar to that of your treadmill and phone, that's how". Oh alright, thank you.

CaPILLARies
Yh and also the diagram was of a blood vessel not a capillary as they are ALOT smaller
I don't see the issue. How is his pronunciation wrong?
It depends which country you come from. Here in England (and also Luke), we pronounce it "Ca-PILLAR-ies" whereas I know in most, if not all, parts of USA it's pronounced "cap-ih-LARRY"
Wan Wan yeah he pronounced it wrong but its ok
What is the best alternative to a Fitbit?
Garmin
I have a fitness bracelet that i've bought in order to track my steps amount ,my heart rate and .so on
In order for that device to work correctly, i need to sync between the bracelet and my smartphone , question is do i need to take my smartphone with me every time i go for a walk for tracking steps amount ?
Thanks
*How fitness trackers actually work:*
1. You spend a lot of money
2. You have a tracker which reminds you everyday to do sport
3. You start ignoring it
4. You get fat anyways
uhhh
TL;DR
There's stuff in there that works
and that would be probably the TL;DR of every piece of tech ever, of your logic is solid. not only electronic tech, but anything... even Rocket science!
TL;DR, he's right.
light sensor* that's it lol
I'm holding out for tri-corders from TNG.
I can't imagine how useful it would be to know what minerals/vitamins/nutrients my body is actually lacking.
haha, I love TNG. Roddenberry's Star Trek series' medical/technical/scientific stuff is based on actual theories and probabilities he researched for the show. Sadly, many articles that compare modern devices to the tv series believe it's the other way around -- that technology today is mimicking the tv series. Wouldn't that be like saying Roddenberry had an IQ of, like, 186? LOL. Fitness trackers are actually based on the early prototypes for real tricorders.
Hows that going?
I just got back from the gym and see this :D good timing guys! :P
I just got back from Krispy Kreme and see this :D good timing guys! :P
I didn't go anywhere today but still I see this :D good timing guys! :P
Does you have to turn the GPS on the count step and calories
hey LMG could you do a quick explanation session on the types of processes like 16nm process ,14 nm process etc what do these mean generally
your the best new asset to tech tips pal
So may I suggest you guys review the Empatica E4 wristband. And their embrace watch?
is that fitness tracker comparison video/comparison coming out soon?
Thanks fitness tracker, I almost walked right into that volcano
LPT: Try to do 100 squats, 100 crunches/sit ups, and 10km of walking or biking a day, and you'll see great improvement.
and if you havent gone bald; repeat
could you give your source for this video? I'm working on sth and need it
Fresh books will keep you fresher, less stress, less sweat, less bad smell
What if I take 2 min breaks in between?does it adjust accordingly
they should make a taste detector that you put in your mouth so that when fast food is felt you get shocked 😂😂
LOOL
Craziest comment ever 🤣😂🤣😅🤣
That was the oddest way I have ever heard "capillaries" pronounced.
Fuck, I'm a Michigander and I know what a fuckin Timmy's is, eh!
Same here, but i guess in Canada people are obsessed with Tim Hortons. Most people i know around here are typically kinda "meh its okay" about it.
+patriot1028 we aren't obsessed with it.The problem is;unless you're in a major city;Tim Hortons is typically your only option other than making it yourself
Jakebg19 Oh, that makes a lot of sense and sounds very reasonable honestly. There's probably 15 different places to get coffee in almost any direction from my house, not to mention the 1500 different hipster coffee shops in downtown area's.
patriot1028
wow,i wish we had that many choices.Only a Tim Hortons and Mc Donalds where i live(20k"ish" people).Tim Hortons has a monopoly on the Canadian coffee market.I personally like it,but it isn't like i have a whole lot of options either lol
Fellow Michigander! Yeah, we have like 50 Timmy Ho's around here, and only 2 Krispy Kremes in the state, and I love it that way! Actually, one of the Krispy Kreme's just burned down a couple blocks from my house.
I love how lmg is Canadian ❤
You should do some video about best one trackers...
I think it's pronounced cal-pill-er-ees
capillories. When you want to get really stoned.
kappa-larrys
Thumbs up for kappa.
which wavelenght does oxymeter use?
Thank you
Please make a video on the 'Turtle beach Hypersound glass speakers'...

Can you do a Vo LTE fast as possible? Call quality update?
Great information 👍 hi from the u. K
I need that Bloodflowsample.wav !!!
What is the Virtual memory in the advanced system settings and what its used for ?
Same question
Simple: RAM is small bucket, Virtual RAM (the HDD/SSD) is big bucket. Put small bucket into big bucket, now fill small bucket with water (the running applications)... eventually that small bucket will overflow (aka you used up your fast access RAM) and begin to fill the big bucket (slow access) without losing any water.
in layman terms: it's just a secondary storage space to store running applications when your primary runs out or is getting to its limit. Secondary storage is much, much slower.
When your computer runs out of memory, it creates a page file (windows XP) or something like that. It is on your hard drive and is used for less used data in your memory.
At least I think
Dylan Hu you got the jist of it :)
0:33 the hum is real
Is linus' Twitter really beeing hacked ??
its the fucking poodlecorp group. They are just assholes that think they are funny.
no it was a youtuber with 5+ mil subs
Poodlecorp? What a pansy name. Of all the dogs, they use poodles. Fucking chihuahuas are more threatening than a poodle.
smh.
What exactly is funny about ruining the integrity of something someone makes a living off and that multiple thousands of people enjoy watching?
Instead of using their skills for something good, they decided to be childish with it.
Falxhor some people are idiots.
The Hackers could have used their skills to shut down bad websites/social media accounts, instead of ruining for innocent UA-camrs that a lot of people like watching.
You may get less famous for it, but it is in a good way, instead of a bad way.
People that are the serial killers of hacking, in the way that they dont care if most people hate them or not, they just want attention, they dont care if it is in a good or bad way.
Best Tracker and smart watch: Basis Peak
Hmmm ... I still don't know how it works. So how does it count and measure steps?
In this day and age you gotta exercise and eat well to lose weight. As much as I wanna be skinnier, I'm not giving up food. Not worth it lol, I'll just stick to working on exercising.
I find it odd that medically speaking people discount heart rate completely w.r.t trackers when it comes to other activities like lifting weights or even riding a motorcycle. Your heart rate is the main measure of how much exertion is placed on your body whether still or moving or moving on the spot. Sure they may be off by a bit but it's not some massive 50% difference that you're going to notice. This theory aligns with all the numbers I've been tracking so far.
Heart rate doesn't measure strain on your body, just your heart. Heart rate is not a good indicator of physical activity. While certain activities that require you to be active, like lifting weights, or more alert, like riding a motorcycle DO increase heart rate, so do a lot of other things that don't require any effort.
For example, I can raise my heart rate by 30 BPM when I'm sitting on the couch watching UA-cam. I can achieve the same level of "aerobic" heart rate as someone on a brisk walk, without actually engaging in any exercise. All I have to do is drink some beer and sniff some cocaine.
The function of the heart is to transport oxygen, CO2, and various molecules secreted by the muscles and organs around the body and deposit them where they need to be. You can think of it like the post-office. The heart pumps blood, which goes around picking up all the messages sent by one part of the body to another, and delivers them to the address on the package.... Along with all the junk and spam injected into the system from 3rd parties, like caffeine, alcohol, and pollutants.
During aerobic exercise, you aren't necessarily exercising your body as much as you are your heart and lungs. That's why it's called AERObic exercise. Your heart is a muscle, and aerobic exercise is like doing high reps, low weight strength training. You don't build mass, but you do build endurance. When you do cardio for 30 minutes or longer, you're increasing the hearts endurance. More endurance means more blood flow, which means more oxygen, less c02, and better response time to chemical messengers. When you improve your heart health, you increase the amount of time you can do moderate, sustained physical activity.
During strength training, your heart isn't being worked in the same way. Sure, lifting does raise the heart rate, but it's done in short bursts. Not only that, but the role the heart plays in lifting vs cardio is quite different. During cardio, the heart is working to scrub co2 and supply oxygen. Your body is smart, and when it detects a certain level of co2 in the blood, the heart goes into oxygen mode. It will constrict veins going to non-vital organs, and expand those going to the lungs and heart in order to increase the speed at which the blood reaches the lungs where the co2 can be expelled, and replaced by oxygen.
This doesn't happen immediately though, it takes the body about 20 minutes to "switch" from a resting state to an endurance, cardiovascular state. If you've ever practiced any sort of long distance running, you'll be very familiar with this transition and how it feels. This is also what produces the effect known as the "runners high," since the restricted blood flow prevents chemical messages from reaching the muscles as efficiently. As you run longer and longer, the pain signals from your muscles (which are electrical and travel instantly) trigger the release of endorphins. Since the blood flow is restricted, fewer endorphins are able to reach the muscle. The pain signal keeps being sent, and the brain continues to reply by signaling the release of more endorphins. Eventually, they build up in the blood stream producing a somewhat euphoric effect.
In some males, after a long enough period of cardio, this change in blood flow can cause the prostate sphincter to relax, due to lack of pressure. It's more common while using weighed arm bands, or carrying weights during a run. Doing so puts more demand on the core muscles to stabilize the body, increasing blood flow the abdomen. The most efficient way to increase pressure in the abdomen, is to reduce pressure to the genitals. In certain cases, this can cause the runner to release seminal fluid. Some individuals will also experience a true orgasm.
But none of that is going on during strength training, at least not to that level. During strength training, your heart is focused on 2 things - supplying energy to the muscle, and removing lactic acid. Even if you go from set to set to set with minimal rest, your body will not respond in the same way it does during cardio. During strength training, what you're doing is tearing muscle fibers. Your heart is playing damage control. Yeah, your heart rate is gonna go up - but for completely different reasons. Your body is signaling pain, and your muscles are being damaged. Your heart responds by modifying blood flow to reach the site of injury. Unlike the cardio response which takes 20 minutes, the response to tissue damage happens within a few seconds of injury. Special proteins in the blood attach to the broken tissue and sort of make a scab. After that, mitochondria begin absorbing and expelling calcium from within the muscle tissue. Then, several hours later, after the injury has stabilized, microphages are released that eat away the scab left by the proteins, allowing the tissue to regrow stronger.
So no, heart rate isn't very important during strength training, because you're not exercising your heart. What you're doing is destroying thousands of tiny fibers in your body, and relying on your heart to provide the components necessary to fix them.
@@zap_collection6511 that's an incredible depth of information. Thank you for all of the details and taking time to type it all out 👍🏻 I know that if you're not an averagely healthy individual, your heart rate can be up just by sitting and doing regular stuff. I also understand that you can forcefully spike your heart rate by doing various things. What you CANNOT ever do however, is to push your hear to spike continuously like that without actually doing it or yourself harm or stressing yourself to the degree where you cannot continue to sustain it. Period.
Caffeine, redbull, energy drinks, heck even sex will amp your heart rate high and continuously. So does viagra too. But just because one is Humpty Dumpty away in bed doesn't mean they're burning 600 calories like the watch says it is. This is why watches aren't the most accurate at measuring your calories. BUT. They are the most consistent per person. They're also not THAT far off from actual calories burned. A maximum of 15-20% as per some studies if you possess the niche/peak devices in the market today. That's because they don't only measure the intensity of blood flow through OD methods but also use different wavelengths of light to do the same. They also use geolocation positioning to measure movements and subtle movements as well like that of your in correspondence with your body and the other parameters along with it to make many tiny calculations to give you the results.
I also did this research on myself once. To calculate my calorie in/out and other parameters and estimate by when I can lose X amount of weight if I did Y amount of calorie burning (as per the watch). Interesting thing is I was off by a 12% margin by the end of 6 months. I'm going to repeat this again and kick start my fitness journey with more data to monitor. Let's see if the watch stands up to the consistently (slightly off results) or fails utterly 😅
As of today we unfortunately don't have better more efficient or accurate means of tracking. I consider smartwatches the same as weighing scales. Not the best at what they do to tell us how much we did or how much we lost. But they get the job done just about enough with just about enough consistency to keep us going on a certain path of progress. They're by no means the DEFINING solution nor metric we should focus on but, they're what we have now. And the only Main measure of what we possess to scientifically predict things.
Unless you're rich and well to do - that's a whole different game altogether. Research clinics and niche hospitals do possess the equipment to track it to the tee with O2 consumption, CO2 expulsion, heart rate, etc. Wish I could have one at home 🤣
Can you guys do a video on why each model of Intel CPU has multiple versions?
I mean like how there's the 4790, 4790s, 4790k and 4790t. What's the difference between them?
Do a techquickie on Canada
What you talking about.. Vancouver doesnt have Tim Hortons... last time i went, finding a Tims was like finding a needle in a hay stack... the hay stack being Starbucks. xD
I like this.
I found a Tim Horton In Minnesota.
"Speaking of keeping your body fresh and fit, Freshbooks, isn't for your body, it's for your accounting."
gg Luke
Lanthaniel haha this was such a coincidence, the moment Luke said it, i read it here 😂
I put it inside my pocket and still count steps and zone minutes is it correct
My garmin forerunner + Endomondo is great :) Danish app ! Anyway you won't burn shit from doing running etc, all about food you eat...I dunno what my stats are, but like 500 KM running is what 50 burgers or some...nothing
I'M SO FIT I'M FIRST TO THE COMMENTS
How about a buyer's guide of said Fitness Trackers?
>How do Fitness Trackers Work?
It just works©
@0:05 who saw that 😁
@2:02 ...Wrist movements?
Now I just need a Friendzone Trackers
that transition into the ad though...
What a coincidence! Just got my Mi Band.
Not a coincidence, 👹
@@user-xk9tn1zi2m Ayo, after 6y!
I have a fit bit versa
Where do they get the pictures for these videos? They all look the same.
Tim Hortons? Canada? Look, mate, Buffalo is as addicted as Alberta when it comes to Timmy Ho's. Don't forget us!
What's the cheapest fitness tracker for my cycling activity ?
Id just get runtastic on your phone
mi band is pretty cheap
Ethan Chow Yes, but I've heard that it only works for running, and not for cycling..
More Luke is always better.
Calories in/calories out doesn't work anyway. The body adjusts its resting metabolic rate to account for extra calories coming in or being burned (or fewer on each). It takes a huge swing in either direction to affect your weight that way. The main advantage to exercise comes in different forms for different exercises.
Weight lifting and resistance training builds muscle, which increases your metabolic rate and your body's ability to burn excess sugar quickly, as well as extra fat when your blood stream isn't flooded with insulin. Walking and sprinting decreases your insulin resistance, decreasing the effect that an insulin response has on your weight gain.
this dude is exactly the person im glad that covered this theme, because i still think he looks like and dresses like some who really is for a gym. hes like ex-gym dude gone IT-nerd
How are calories counted?
Woot timhortons shout out
Fitness trackers have a long way to go, cant comment about the higher priced ones. Its a known thing that a person can cheat, number of steps and heart rate. It would be great device to have as technology advances and pricing drops, just not now.
FYI... Handphone have been proven to be more accurate. just that you dont have a heart-rate monitor. etc
girl lying on bench at 2:12 is really cute
Capillaries lol you said it so wrong
Is all a gimmick...I eat twice as much calories around my family and I just sit on the computer all day, been the one with lower weight around the house by far (relatively, in good shape).
Most of my energy is burn inside my head and tension around my entire body muscle. There is no smartwatch that measure this to be honest but yeah, is nice to know how much you run when you go for a stroll I give them that. I always like those old school odometers back when I spend all my time on a bike.
RIP Linustechtips.com. Poodle Corp was 2 dank 4 u.
Wait... how did Luke pronounce capillaries?
It's my b-day! :D
i don't know why, but monitors that use electrical impedance just plain don't work. the data always ALWAYS just looks like raw input from an accelerometer. no problem with the ones that use light, though.
It varies by the water content, so if you sweat more the impedance drops no matter how fast your heart is beating.
Well luke, you can see them go up when for example some1 twitter got hacked and there youtube is about to be hacked :p
You are talking about Linus right?
yes
My moto 360 has the worst step tracking ever. I wore that and my friends Garmin vivoactive one day and my moto got about half the vivoactive
Does this fitness tracker have 32GBs of RAM? Because my PC has 32GBd of RAM.
Canadian viewers? I'm from Ireland m8
Dammit, now I want a Burger -.-
Went your heart beat goes 31bpm is it bad
Odd... my sons fit-bit says he had walk 10,000 steps today but he never left his room...... Now that I think about it he did get a package from his girl friend and a few new CD's...... meh........ XD
+Techquickie Linutech's Twitter just got hacked by poodlecorp🙈
thanks for explaining nothing you literally said everything they do and just a few things about how they do it but just the basics that pretty much everyone knows it lights up when I'm checking my heart so no shit it uses late to do that maybe get a little bit more complex and explain how the sensors really work I don't know maybe I just know too much about these things but I came to learn more and Now I'm moving on oh yeah sorry for being an asshole I'm just not in a great mood the milk machine what am I saying the milkshake machine was being clean at checkers so I couldn't get a milkshake how about you clean the milkshake machine when you're closed and if you're 24 hours open and you don't close there should be a specific time when you clean the machine and everyone should know this so they don't go there and ask for one and get pissed off when you can't make it but yet you have ice cream that's weird
1:30. not realy. they dont messure how much blood its flowing, ther messure if its flowing or not (aka pulse). also they messure the oxygen level. witch isnt realy importand for fitness - if ure not klimbing mount everest or suffer from COPD.
