Cardio Stops When You Stop Moving But Muscle Keeps Burning Fuel

If your fat loss plan is basically “more cardio and less food,” and you keep hitting the same wall, we made this one for you. We get into the real differences between strength training vs cardio and why so many men over 30 grind on the treadmill, sweat buckets, see the scale bounce around, and still struggle to lose body fat in a way that lasts.

We talk through a few of the biggest cardio myths: how calorie burn is often smaller than it feels, why a sweaty session can drop water weight fast without touching fat, and how that quick scale change can trick you into thinking you “earned” extra food. Then we shift to why resistance training changes the game long term. When you lift, you force your body to repair and rebuild muscle, and that recovery costs energy beyond the workout. More muscle also acts like a bigger engine, supporting your metabolism instead of slowing it down.

We also connect strength training to insulin sensitivity in plain language, explaining how muscle helps manage glucose after meals and why that matters for accessing fat stores. Finally, we keep it simple with a practical weekly structure: lift three to four times, walk often, and use cardio two to three times per week as support, not as the whole plan.

Strength Training Vs Cardio Basics

SPEAKER_01 0:04

Hey, what's going on, guys? Welcome back to Tut Radio. So, today we're gonna be talking about something pretty simple. We're gonna be talking about some of the differences between strength training and cardio. And if you're a guy over 30, right, it's one of those things I think cardio that you naturally will gravitate towards when it comes to your weight loss efforts. It's what you see a lot of your friends are doing, you know, things like that. And I think that when people are initially trying to lose weight, cardio is the thing that they're looking for when it comes to what kinds of exercises they're gonna be doing. So, again, today we're just gonna be breaking down some of the like the key differences between doing strength training regularly versus you know avoiding it and just kind of doing cardio. So adding cardio to your day is good for definitely a couple of different things, right? Primarily, you'll see the benefits in your heart and in your lungs, right? Because this is what when you do cardio, these are the pieces of your body that it's going to primarily benefit, right? And in everybody's defense, right, it does burn a few extra calories throughout your day. But I'll put it into perspective for you, right? If you're a man, right, and you're 180 pounds, right? You're walking at a moderate pace and you go for an hour, let's say on the treadmill, you're walking outside, whatever that looks like, it's only gonna burn about 300 calories or so. So a lot of people think that when they're doing a bunch of cardio, they're sweating a bunch, which we'll get into here soon as well, that they're they're burning a bunch of calories and they can kind of start to justify eating more because they think the deficit they've just created by doing cardio

The Calorie Burn Reality Check

SPEAKER_01 1:40

is a lot bigger than it actually is, right?

SPEAKER_00 1:41

Hey, Vin, can I can I interrupt you just for a second? Sure. And and that is, it's interesting, right? And this is an important topic to talk about today. And the reason why is because, like you sort of said in the beginning, it is everyone's first decision when it comes to, oh wow, I gotta get back in shape, I gotta lose some weight. They immediately go, okay, well, I gotta go crazy on cardio and burn calories. And it's so funny because when we start people on a new program, we it it's comp they're almost shocked because it's completely different. And and cardio always ends up being a part of what we we kind of program, but it's never first and it's never the sole part of the weight, the weight loss journey for sure. So I just kind of wanted to add that in there because I think a lot of people will resonate with that simple fact because they know, yeah, that's right. When I go to try and lose weight, that's where I always start.

SPEAKER_01 2:34

Right. Yeah. Again, I think it's just a matter of people they think that because they see people in the treadmill when they're trying to lose weight, that that's like the natural assumption that people can make is that, okay, well, maybe I ought to try this cardio thing out. And again, it's nothing wrong with doing cardio. This is not the point of this podcast, it's just what is better than the other when it comes to maximizing your time, making sure that you're doing things that are going to make your body super efficient at burning fat, things like that. So, again, one of the main misconceptions of cardio is that it is a better, you know, usage of your time when it comes to actually burning fat, even better than strength training itself. And so, what people don't understand is that when you are doing cardio, yes, you're burning extra calories throughout the day, whatever methodology you're using, bike, you know, again, you're going on a walk, you're swimming, all these things, it is going to burn extra calories throughout the day. But once you stop doing whatever you were doing, again, once you stop walking, you're gonna stop burning calories, right? Because it's only going to serve you that purpose as you're in it, right? Whereas something like strength training, what you're doing when you go to actually go to the gym and do resistance training and break down the muscle and come home and actually build the muscle is that you're kind of manipulating the way that your body is going to use the energy that you give it. So now, for example, when you go home and eat, right, you're going to actually use some of that energy to actually restore and repair the muscle that you just broke down at the gym. Well, that requires energy for you to continuously do this restoration and repair process. So, in the long run, you know, you might, if you if you're doing sprints, you might burn more calories in the short term than if you were to do, let's say, just a regular upper day at the gym. But long term, because of the energy required to restore and repair the muscle that you broke down during resistance training, it's actually going to burn more energy. And so, again, it's just one of those things that people maybe don't consider, right? But it is true that cardio is just going to stop burning energy for you as soon as you stop doing it.

Where To Follow And Ask Questions

SPEAKER_00 4:36

Yeah, I mean, so look, again, this is an important topic. And I want to make sure, just in case, you know, you're listening today and you didn't know, you know, you can follow uh Time Under Tension on all socials. And we also post uh a weekly article that's related to the podcast on Substack. So, you know, please, you know, check it out, and uh, we'd really appreciate it. And of course, if you ever have any questions about the podcast, you can always go to the fan mail section uh wherever you listen to your podcast and go ahead and hit that, and we'll be more than happy to actually reply back. So actually, it's kind of fun for us to

Sweating And The Water Weight Trap

SPEAKER_00 5:10

do that. So, anyway, the next piece I'm gonna talk a little bit about is a second myth, and this is funny too. And I was thinking about this from when I was wrestling back in seventh and eighth grade, which was like about a million years ago. But a lot of people think, man, I got a great workout, I was sweating like crazy, you know, I lost a couple of pounds. And what people think is like, you know, then why is it then, okay, I spent a whole week in a calorie deficit watching my macros, tracking my food, and I lost one and a half pounds, and they're frustrated by that. And then they'll go and they'll do one cardio workout, and then they come home and they realize, wow, I just lost three pounds. Well, because one, the cardio workout, that's sweat, that's water weight. There's a big difference between the water weight and fat. And so the water weight, and I think people forget, they don't realize one gallon of water weighs uh around eight pounds. So, and I've done this before, you know, I've I've gotten on my bike and I'm okay, I'm not gonna I weigh myself and then I'll go, okay, I'm just gonna ride. I'll ride for like 20 miles, come back, don't drink anything on the ride, and then weigh myself again, and I'm down four pounds. And so all that means to me is that I just simply lost about a half gallon of water through sweat. So that's an important piece. So, you know, you you you don't really lose, you lose weight, right? Because you're losing, you lose water weight, you're not losing fat weight in in the long term. What we're trying to do is actually lose fat. So that's super important. And I think we're not gonna get into it today, but really fat loss requires a systematic approach besides again building muscle. So that again, because building muscle is a part of that systematic approach that we take, helping people gain, you know, I'm sorry, lose weight and do so for the long term, because that's super

Muscle As Your Metabolic Engine

SPEAKER_00 7:06

important. So, anyway, there's a uh another myth, and that is that lifting is just for building muscle. So there's more to it than that, and so let's kind of talk about this one. It I want you to think about all the muscles in your body and and kind of think of that as one giant engine. And I think Vin was talking about this. That engine requires a ton of energy to keep going, and so but your fat stores require zero energy to maintain, there's nothing to maintain, they just sit there waiting to be used, and that's really kind of important. So remember, you know, as you're working out, the bigger your engine, the more that you're gonna actually burn. And that's why we always program along with the whole foods diet and along with you know time-restricted eating, we're always gonna program some sort of strength training because that is a really, really important piece. So, and so what does strength training do? Also, well, it builds and keeps muscle, like Vin talked about. But the part that I'm gonna talk about now is that it actually improves insulin sensitivity. And so, what what does that mean? Well, we've talked about this on other podcasts, and it's really important to understand if insulin is in your bloodstream, the body goes into storage mode, meaning that it will not find or use energy from your fat stores so long as insulin is present. It isn't until insulin has done its job by removing all the the glucose in your bloodstream, because that's its primary job, into your cells for before so that you can use that energy. If if we don't, if that doesn't happen, fat loss doesn't happen either. So here's the thing: this is really important. If you have a large amount of muscle mass, after you eat something, the body breaks down your food into glucose, which ends up in your bloodstream. Well, muscle actually can store that glucose. So it pulls some of the glucose out of your bloodstream. The same thing like with your liver. Your liver can store some of the glucose too, which is really important. So when that happens, now all of a sudden there's less glucose in the bloodstream, now there's less insulin in the bloodstream. So once now that piece is taken care of, insulins, then okay, no more food. All the energy is kind of allocated where it belongs. Now, if we need energy, we actually can use it from our fat stores. So that's another big important part about the the muscle piece that I don't think people understand. And that's this whole discussion about macros and protein here all the time. So, you know, just kind of keep that in kind of in the back of your mind that the muscle really does, it helps improve your metabolism. So super, super important.

A Simple Weekly Plan That Works

SPEAKER_00 9:58

Okay. So then the last thing I think that we want to kind of talk about and tell people that, you know, it's neither because there's always this argument you see you hear on the internet, you know, which is better for fat loss cardio or strength training. You know, can you kind of heard what our kind of take is on it, but it's really important that it's it's reit, it's really neither in the sense that we we want you to do both. And for me, cardio is like it helps me relax, it helps me like kind of get I'm out there by myself if I'm riding my bike and I can kind of like be alone with my thoughts, so to speak. And so that's a big part of it too, and it helps me sleep better, so it has a benefit there. So I I don't I don't want to say that you know you should just completely ignore the cardio piece of it, it has a role, and I think it has an important role, it's just not as effective when it comes to losing weight when you're referring specifically to fat loss. And so to make this simple, it's like strength training helps build a strong machine, and cardio is kind of like the tool that supports that machine, right? So it's kind of really, really simple, right? So strength training is if you want to look at it this way, is like you know, your weekly salary. You know, you constantly have you got money coming in, it's you're building and you're investing in yourself, and then the cardio is like kind of doing Uber, do Uber Eats on the side, you know, it's just a kind of nice, a nice addition, but the you know, the reality is that you need that steady paycheck in order for longevity, and that's really important.

SPEAKER_01 11:37

So okay, so to keep this very, very simple, right? Because it it doesn't need to be overly complicated, right? If you're a guy in your 30s, right, and you're looking to lose fat, what you should be doing is prioritizing the resistance training piece of it. So, again, my recommendation is that you lift weights about three to four times a week. That's gonna give you a chance to hit each muscle group about two times, which is what the science suggests is the most efficient way to actually build muscle over time. Make sure you're taking the sets close to failure. That way you're gonna make the best usage of your time that you're spending in the gym doing resistance training. Two, walk. Walking is extremely powerful. Or ride your bike again, like my father does. It's good for your head, it's good for digestion, especially after a meal. You know what I mean? Get outside, you go take a 10-15 minute walk, it's gonna help you feel better, you're not gonna feel as bloated. There are other use cases for cardio that are positive that are outside of burning the immediate calories of doing cardio. And when you do do a dedicated cardio session, do it sparingly. Two to three times a week is fine. Again, it's it's a way for you to, again, create a little bit of a deficit throughout the day. Nothing crazy. You should feel good. Sweating is good. There are other good properties of sweating things out that I think are good, at least anecdotally. So it's not that anything is overly bad, it's just okay. When it comes to strength training versus cardio, in the long run, what is more important in supporting uh fat loss over time and then keeping the fat off of your body? We both believe that resistance training kind of trumps cardio in that sense. But again, not to say that it's not important, but it has its place. And yeah, that that's my take on the whole

Why Most Fat Loss Plans Fail

SPEAKER_01 13:16

thing.

SPEAKER_00 13:16

Yeah, to simply recap the whole thing and say, well, why do most people kind of fail at fat loss? Because this is what we just talked about. I mean, this is the approach that they take. And so, you know, they overdo the cardio, then they try and starve themselves, they underat, and then they don't build muscle. And so the result ends up being you know a slower metabolism, they plateau, which is super, super frustrating, and that's where they end up, just uh aggravated. You know, ultimately, that approach, if you if you don't make this change that we've been talking about today, then you know, it's kind of like the approach is you end up trying to shrink your body instead of fixing really what's really wrong with it. So that's that's where this kind of ends up. And so hopefully that's that's the key here. People like really take away from all this today. So to wrap this this all up, you know, if you've been stuck doing more and more cardio, kind of that's your sign, right? There's a better way to structure this. Okay. So if you you know want some additional answers, you can visit our profile on Instagram and drop a follow, or feel free to DM us with any questions you have so that maybe we can help you, you know, get pointed in the right direction. So, again, hopefully this was super helpful today. And uh, as always, we thank you very much and we will see you next week, Vin. Thanks, guys. All right, everyone, we'll talk to you soon.
