Cardio Machines Are Lying to You!
42sExposes the shocking truth that gym machines deliberately misreport calorie burn, sparking curiosity.
▶ Play ClipGym cardio machines often display inaccurate calorie burns, overestimating by up to 42% due to assumptions like a standard 154-pound user and including resting energy. The video explains how machines calculate calories, why they inflate numbers, and how user form further reduces actual burn. It ranks machines by accuracy and offers practical tips to get better results.
Cardio machines often calculate calorie burn based on a standard 154-pound person using MET (metabolic equivalent). If you weigh less, you burn fewer calories than shown; if you weigh more, you burn more.
Many machines intentionally include resting energy expenditure (REE) in the displayed calorie count, inflating the number by ~100 calories per session to make the machine seem more effective.
Leaning on handles or poor posture can reduce actual calorie burn by up to 50% because less body weight is being moved.
Short, choppy steps reduce range of motion and work done, leading to lower calorie burn compared to full hip extension.
Accuracy ranking: Stationary bike (~7% over), stairmaster (12%), treadmill (13–20%), elliptical (up to 42% over).
A 30-minute elliptical session can overestimate calorie burn by 130 calories daily, leading to ~14 lbs weight gain per year if eaten back.
Air bike, rowing machine, and ski erg burn 20–25 calories per minute and involve upper body, making them more effective alternatives.
Use breathlessness to gauge effort, input body weight if possible, or simply divide the machine's number by half to avoid overeating.
"The title promises a ranking of best/worst cardio for fat loss; the video delivers exactly that with data and actionable tips."
Why do cardio machines overestimate calorie burn?
Cardio machines often overestimate calories burned due to using a standard 154-pound weight and including resting energy expenditure.
2:12
By what percentage can leaning on a machine reduce calorie burn?
Up to 50% less.
3:51
List the four types of cardio machines in order of accuracy, with their typical overestimation percentages.
Stationary bike (~7% overestimate), stairmaster (12%), treadmill (13–20%), elliptical (up to 42%).
5:36
What are three practical ways to make cardio calorie estimates more useful?
Cover the display and use breathlessness as a guide; divide the displayed number by half; use a machine that allows body weight input.
8:33
How much weight gain could result from overestimating 130 calories daily for a year?
14 pounds.
7:15
What does MET stand for, and what does 1 MET represent?
MET stands for Metabolic Equivalent; 1 MET = calories burned sitting still, and higher MET values represent multiples of that baseline.
1:46
What is one intentional trick machines use to inflate calorie numbers?
Including resting energy expenditure (REE)—the calories you'd burn doing nothing—into the total calorie display.
2:46
What is the key message about diet vs. cardio for weight loss?
You can't outrun a bad diet; a single meal can erase an hour of cardio.
0:54
What is the range of inaccuracy for wearable devices in estimating calorie burn?
20% to 96% inaccurate, depending on the device.
9:22
Name three effective alternative cardio machines that engage both upper and lower body.
An air bike, rowing machine, or ski erg.

8:48[00:01] You burned 463 calories.
[00:05] You burned 641 calories.
[00:10] You look so handsome.
[00:14] >> Yes, you. You sexy beast. That beard is
[00:18] ravishing.
[00:23] >> So, I got some bad news for you. This
[00:25] machine right here is lying to you. But
[00:28] it's not just this one. So is this one
[00:31] and this one and even this one. You see
[00:34] guys, if you're using a treadmill or any
[00:36] cardio machine right now to determine
[00:38] the amount of calories you're burning to
[00:39] help you in your goal to lose more
[00:41] weight, you're not getting the right
[00:42] math. The number of calories that you're
[00:44] burning are just not accurate. It's time
[00:46] for the truth. But the first truth that
[00:48] needs to be told is if you're using your
[00:50] cardio as a way to create your caloric
[00:52] deficit to lose weight, you're making a
[00:54] big mistake because you're never going
[00:56] to be able to outrun a bad diet. We talk
[00:59] about it all the time. Even just one
[01:01] slip up in a meal is enough to erase an
[01:03] hour's worth of effort at the gym. You
[01:05] need to make sure that when you're
[01:06] trying to lose weight, your efforts are
[01:08] focused first and foremost on cleaning
[01:10] up the foods that you're eating right
[01:11] now. Make your caloric cuts there and
[01:14] use the additional cardio to supplement
[01:16] those efforts. and that's when the real
[01:17] results will happen. So, the first thing
[01:19] you have to be on the lookout for is how
[01:21] these things are actually asking you for
[01:23] the information because if they're not
[01:25] asking you for your weight directly,
[01:27] then they're not giving you an accurate
[01:28] result. Because we know that cardio
[01:30] machines need to know how much you
[01:32] weigh. A heavier person has to work
[01:34] harder to move their body through space
[01:36] and therefore can burn more calories
[01:37] whereas somebody that's lighter is going
[01:39] to burn less calories for the same
[01:40] activity. Well, what happens with these
[01:42] cardio machines is they calculate that
[01:44] calorie burn based off of something
[01:46] called a MET, me, which is a metabolic
[01:49] equivalent. And essentially, one MET is
[01:51] the value of you sitting on the couch
[01:53] doing nothing. The calories that you
[01:54] would burn by literally just sitting
[01:56] down watching TV. And anything you did
[01:58] that increased your activity beyond that
[01:59] is going to be some multiple of that
[02:01] number. So, if you went for a jog, you
[02:03] could have, let's say, a three or four
[02:05] met burn, which is three or four times
[02:07] harder than sitting on your ass. That
[02:09] being said, it's always calculated by
[02:12] one body weight number, usually 154
[02:15] pounds. So, if you don't weigh 154
[02:17] pounds, you're not getting an accurate
[02:19] calorie output read back to you. If you
[02:21] weigh less than that, then you're
[02:23] actually overestimating how many
[02:24] calories you burn. And if you weigh more
[02:26] than that, you're actually maybe
[02:27] underestimating by a little bit. But
[02:29] don't worry, there's a lot of other ways
[02:30] that these machines are screwing you.
[02:32] I'm going to show you those, too.
[02:34] >> Wait, isn't this your towel? H.
[02:37] >> Oh, that's disgusting. And one of them
[02:40] is by actually maybe fudging the math
[02:42] intentionally. You see, a lot of times
[02:44] the number that you read in terms of the
[02:46] caloric burn is based on including
[02:49] something called the RE or the resting
[02:51] energy expenditure, the calories that
[02:53] you would burn normally at rest. So,
[02:54] let's say you're on the treadmill and it
[02:56] tells you that you burned 420 calories.
[02:58] Well, what if it's also including the
[03:00] fact that you would have burned 100
[03:01] calories if you did nothing at all?
[03:03] Well, that's just inflating the overall
[03:05] number. you only burn 320 extra
[03:07] calories. You're already likely using
[03:09] that number in your base calculation to
[03:12] determine how many calories you need to
[03:13] burn during the day. It's just not fair.
[03:15] So, you might be asking yourself, why
[03:17] would they do such a thing? Well, maybe
[03:19] to make you think, this machine is
[03:21] amazing, and I would love to do all my
[03:23] workouts on this machine. And a matter
[03:24] of fact, I might want to buy one of
[03:26] these and put it in my house because it
[03:27] makes me feel good about the number of
[03:29] calories I'm burning. Just throwing it
[03:30] out there. But let's not just blame the
[03:32] machines entirely. Because if you're
[03:34] doing what I'm doing right now, you're
[03:35] screwing yourself. If you've ever ridden
[03:37] a bike leaning this way, your posture is
[03:40] creating less caloric burn. How? Because
[03:43] you're doing less work. Leaning on the
[03:45] machine, unweing some of your body
[03:47] weight is costing yourself some
[03:48] calories. Amazingly, so up to 50% less
[03:51] than what you thought you were burning.
[03:53] And that causes problems. You could do
[03:55] it even on a treadmill. You've probably
[03:56] seen it a million times or done it
[03:58] yourself. You hold on with your hands or
[04:00] worse, you lean forward or even on a
[04:02] stairmaster. Any attempt at all to try
[04:04] to unweight any of your body weight is a
[04:06] good indication that you're actually
[04:08] looking for a way out. If you're going
[04:09] to do your cardio, make sure you stand
[04:10] up straight and do so with good posture.
[04:12] You're going to get a lot closer to the
[04:14] number that you actually thought you
[04:15] were burning in terms of calories. Can I
[04:17] ask you a question? If you ever do a
[04:18] bicep curl, do you think you get better
[04:20] results doing this or actually taking it
[04:22] through a full range of motion all the
[04:24] way down and all the way up? Well, it
[04:27] should come as no surprise the form
[04:28] range of motion is better. But then why
[04:30] are you doing this when you're doing
[04:31] cardio? You're cutting your range of
[04:32] motion short often. For instance, if you
[04:35] use a stairmaster or in this case a step
[04:37] mill, allow us to take the option of
[04:39] taking short choppy steps. We don't
[04:41] drive the step all the way down through
[04:43] full hip extension. What that means is
[04:45] less work being done. And for you, less
[04:47] work means less calories and less
[04:49] calories means less weight loss. And
[04:51] look at even your choices like the
[04:52] elliptical machine. It's locking you
[04:54] into an abbreviated range of motion. You
[04:56] can't extend your leg further back even
[04:58] if you wanted to. And then even this,
[04:59] I'm sure you've seen people who stand up
[05:01] while they're pedaling on a bike. Now,
[05:03] this is not just some fancy Pelaton
[05:04] trick. It's increasing the range of
[05:07] motion. You're getting more hip
[05:08] extension, also unaweing your body.
[05:11] Remember, the more of your body weight
[05:12] that you're bearing during the exercise
[05:14] you're doing, the more calories you're
[05:15] burning and therefore getting better
[05:16] bang for your buck. So remember, if it
[05:19] feels easier, often times it is easier.
[05:21] Instead, look to make it harder.
[05:23] Increase that range of motion. And with
[05:25] that increased range of motion and work
[05:26] done, you're going to find better
[05:28] overall success from your time spent in
[05:29] the gym. All right. So, if all these
[05:31] cardio machines are lying to you, are
[05:32] there at least some that are lying to
[05:34] you less? And the answer is yes. And it
[05:36] starts with the stationary bike. It's
[05:38] the most accurate, overestimating by
[05:40] only about 7%. And the reason for this
[05:43] is often times the way that we calculate
[05:44] the calories burned here is through
[05:46] mathematical formulations and based off
[05:48] of power output. In other words, watts.
[05:51] And we do that and we combine it with
[05:53] our body weight, which most of these
[05:54] machines will ask for, we get a much
[05:56] more accurate judgment. However, next up
[05:57] on the list is going to be the
[05:59] stairmaster. Here, we're looking at
[06:01] about a 12% overestimation on the number
[06:03] of calories that you burn. But you got
[06:05] to make sure once again that you're not
[06:06] leaning on that machine, like I said,
[06:07] and that you're taking those nice long
[06:09] full range of motion steps. Next one up
[06:11] down the list in terms of accuracy is
[06:13] going to be the treadmill, which really
[06:14] isn't such good news because so many
[06:16] people use this machine. And the problem
[06:18] here is twofold. Number one, the
[06:20] accuracy is now off by 13 to up to 20%.
[06:23] And even if you do what I told you and
[06:24] keep your hands off the handrails,
[06:26] sometimes you're still fighting a losing
[06:27] battle here because the calibration of
[06:29] the machine is a requirement to maintain
[06:31] its accuracy. And most gyms just don't
[06:33] calibrate the machines often enough. So
[06:35] that's something you can't even do
[06:36] anything about. And then finally, the
[06:37] most inaccurate of them all is the
[06:39] elliptical machine. Sometimes off by as
[06:41] much as 42%, mostly due to the fact that
[06:43] the range of motion varies greatly
[06:45] between even different models. Now, to
[06:47] put this all into real world
[06:48] perspective, imagine this. If you spent
[06:50] 30 minutes on an elliptical machine, you
[06:53] might be overestimating the number of
[06:54] calories burned by 130. Now, think about
[06:57] that. If you're trying to create your
[06:59] overall deficit for the day, and you
[07:01] think you burned 130 calories more than
[07:03] you did, therefore, you can eat more
[07:04] food, you're kind of setting yourself up
[07:06] for disaster. Extrapolate this out for
[07:08] the entire year. If you were to take 130
[07:10] calories in extra over your baseline
[07:12] rate every single day, that's a 14 lb
[07:15] weight gain by the end of the year.
[07:17] Let's face it, we need to figure this
[07:18] out. Or do we really? Because there's a
[07:21] few things you can do right now that are
[07:22] actually going to just nullify the
[07:24] inaccuracy of these machines and still
[07:25] help you to get back on track in terms
[07:27] of your weight loss. And the first thing
[07:29] is just to choose a different machine
[07:31] because there's some that are just way
[07:32] better at burning a lot more calories.
[07:34] So even if they're off, you're still be
[07:36] burning a lot more than you are right
[07:37] now. And the main key here is to
[07:39] integrate one that has working arm
[07:42] movement. Not just going along for the
[07:44] ride like on an elliptical, but actually
[07:45] working and working hard. And one of the
[07:47] easiest ways to do this is with an air
[07:49] bike. You could burn about 20 to 25
[07:51] calories for every single minute that
[07:53] you're on this. The other option is to
[07:54] use a rowing machine. Again, resisted
[07:56] upper body movement as well as lower
[07:59] body movement here. Obviously, when you
[08:00] use these guys, you know how much more
[08:02] difficult they are. The difficulty is
[08:04] going to be a dead giveaway in terms of
[08:05] the effectiveness of the exercise. And
[08:07] finally, you could use something like
[08:08] this ski erometer or the ski erg. The
[08:11] point is you have alternatives to the
[08:13] standard cardio options that are
[08:14] ultimately going to do a better job of
[08:16] helping you burn calories. Yeah, I know
[08:18] they're not the most pleasant, but at
[08:19] the end of the day, what matters is the
[08:21] work that you do. And the more work you
[08:22] do, the more calories you burn and
[08:24] ultimately the more weight you'll lose.
[08:25] So, you got to consider it. But even if
[08:27] you decide that you just want to stick
[08:28] to the machine you're using right now,
[08:30] but want to find ways to make it more
[08:31] accurate, what can you do? Well, the
[08:33] first thing, as I mentioned, is to try
[08:34] to find one that at least allows you to
[08:36] input your body weight. Because when you
[08:37] do, you're going to have an infinitely
[08:39] closer accuracy when it comes to the
[08:41] number of calories burned. But the other
[08:42] thing I like to just recommend is throw
[08:44] a towel over it and stop looking at the
[08:46] calories. Instead, go off of your
[08:48] respiratory rate. The more difficult it
[08:49] is for you to carry on a conversation
[08:51] during exercise, the more indicative it
[08:53] is of the amount of effort you're
[08:54] putting forth. So, aim for more
[08:56] breathlessness. In other words, whatever
[08:58] cardio machine you're using right now,
[08:59] if you're more breathless the next time
[09:01] you use it, you're likely working harder
[09:03] and therefore increasing your calorie
[09:04] burn. Or make it easier for yourself and
[09:06] do what I advise my athletes to do.
[09:08] Simply take the output that the machine
[09:10] gives you and divide it in half and use
[09:11] that to calculate your intake amounts
[09:14] for the day. Oh, and by the way, don't
[09:15] rely on the wearable devices to try to
[09:17] improve your reporting on your calorie
[09:19] output. They're actually not much more
[09:21] helpful. As a matter of fact, the best
[09:22] of them has shown only a 20% inaccuracy
[09:25] with the worst one being actually 96%
[09:28] inaccurate. Yeah, even a blind squirrel
[09:31] finds an acorn once in a while. So
[09:32] remember, if you're looking to lose
[09:33] weight and cardio is part of your
[09:34] equation here, at least make sure you're
[09:36] getting the right numbers back. In the
[09:38] meantime, if you're looking for more
[09:39] proof that trying to outrun a bad diet
[09:40] is a bad idea, you're going to want to
