Starting point is 00:00:00 Hey, this is Mike and welcome to another installment in my in five minutes or less series where I answer one common question quickly and simply because while long form content is great, sometimes it is also nice when someone just gets right to the point and tells you what to do and how to do it in five minutes or less. And that's what I do in these episodes. In this video slash podcast, I'm going to answer a question that I get fairly often, which is what is better for weight loss, weightlifting or cardio? And the short answer is cardio. Cardio is better for weight loss than weightlifting. This has been demonstrated in a number of studies. There's no question. But that doesn't mean that you should be doing a bunch of cardio when you're cutting because
Starting point is 00:00:57 although you might say that you want to lose weight, what you really want and what you really mean to say is that you want to lose fat and not muscle, right? Because that's how you improve your body composition. That's how you, in the end, look the way that you want to look. That's how you avoid winding up skinny fat. And when that's your goal, now weightlifting is much better than cardio. In fact, weightlifting, or at least some form of resistance training, is the only way to preserve as much muscle as possible when you're cutting or even gain muscle, depending on where you're at in your training experience. And despite what you might have heard, weightlifting can also be quite good for losing fat. You see, most people think that if you want
Starting point is 00:01:46 to lose fat, you have to do cardio. If you want to gain muscle, you have to lift weights. That's not true. In fact, cardio, at least by itself, is not a very effective weight loss routine. Studies have shown that many people lose very little weight with a cardiovascular exercise routine. And in fact, some people wind up even fatter than when they began. And there are a few reasons for this. The first is that many people don't understand dieting. At least they don't understand proper dieting. They don't understand energy balance. They don't understand macronutrient balance. And so that of course makes it very hard to lose weight in the first place, because if you don't know what a calorie deficit is, for example, you're going
Starting point is 00:02:30 to struggle to lose weight. But when you combine that with the fact that cardiovascular exercise, especially low intensity, steady state, like LISS, L-A-S-S, cardio, or even just medium intensity, cardio often makes people hungrier. So then in the end, what they're doing is burning some calories, exercising, and then just overeating. And of course, that again is not good for weight loss and can lead to weight gain. Many people also don't realize just how easy it is to eat back all of the calories that you burn during cardio. So for example, if a 150 pound person goes for a 30 minute run, they'll burn somewhere around 400 calories. And that might sound like a large number, but in reality,
Starting point is 00:03:12 if you ate a handful of nuts and maybe a cup of yogurt and an apple, there you go, 400 calories. Or if you ate a medium sized chocolate chip cookie with a little bit of milk, there you go, 400 calories. Or if you ate a medium-sized chocolate chip cookie with a little bit of milk, there you go, 400 calories. Pretty easy to eat back. Now, of course, my point isn't that you shouldn't eat nuts, yogurt, apples, or cookies if you're dieting. It's just that if you don't understand the fundamentals of dieting, it can make it very hard to accidentally maintain a calorie deficit and therefore accidentally lose weight. Hey, quickly, before we carry on, if you are liking my podcast, would you please help spread the word about it? Because no amount of marketing or advertising gimmicks can match the power of
Starting point is 00:04:03 word of mouth. So if you are enjoying this episode and you think of someone else who might enjoy it as well, please do tell them about it. It really helps me. And if you are going to post about it on social media, definitely tag me so I can say thank you. You can find me on Instagram at Muscle for Life Fitness, Twitter at Muscle for Life, and Facebook at Muscle for Life Fitness. Another reason why just doing cardio isn't a great weight loss strategy is your body adapts to the exercise to reduce its caloric expenditure. So studies show that when you're in a calorie deficit, when you are eating fewer calories than you are burning, which is of course necessary if you are going to lose fat, your body strives
Starting point is 00:04:51 to increase its energy efficiency. It's striving to reduce the size of that deficit and ultimately to erase it. It wants to achieve that state of energy homeostasis where input is matching output. And one of the ways that it does this is it increases energy efficiency in exercise. So the more you continue to do the same types of exercise and the same types of workouts, the less energy those workouts will burn over time. So those are a few of the reasons why I recommend that people do really as little cardio as necessary when they're cutting. And I recommend that they focus the majority of their exercise efforts on weightlifting or at least some form
Starting point is 00:05:40 of resistance training instead. And if you really want to maximize fat loss, you do both. You lift weights and you do cardio. And that cardio could be really whatever you enjoy. But if you want to get the most fat burning out of the least amount of cardio, then of course you do high intensity interval training. And if you don't want to do high intensity interval training, then I recommend you actually go to the other end of the difficulty spectrum and go with the easiest form of cardio, which is walking, which actually burns a bit more energy than people realize. If you walk at a decent pace, you don't have to be power walking, but you don't also want to just be barely shuffling your feet. If you're walking with intention, let's say, you're going to burn somewhere between,
Starting point is 00:06:28 depending on your body weight, you're going to burn depending and also depending on the terrain, you're going to burn anywhere from three to 400 calories per hour. That's not bad. So if you combine a few hours of walking per week with let's say three to five hours of resistance training per week, That is really the sweet spot for maximizing fat loss and maximizing muscle preservation and even possibly muscle gain. And this has been shown in multiple studies. For example, one study was conducted by scientists at Duke university. And in this study, they recruited 196 men and women ranging from 18 to 70 years old, and they split them into a few groups. So one group was a resistance training only group.
Starting point is 00:07:12 And what they did is three resistance training workouts lasted about an hour, 24 sets, whole body using machines, simple stuff. Uh, the other group was the aerobic training group. This was the cardio only group. They went for three moderate intensity, 45 minute jogs per week. And then there was a third group who did both of the workouts. So they did both the resistance training and the cardio for a grand total of about five hours of exercise per week. So this study went on for eight months, which is a long study. That's a good duration. This is not a four week or even a 10 week study. It was an eight month study. And at the end of it, what scientists found is that the cardio only group, the aerobic only group lost the most weight, but they also lost a fair amount of muscle. And in fact, they were the only group to lose
Starting point is 00:08:01 muscle. The resistance training group, the people who just did the resistance training workouts, they lost no muscle to speak of, and neither did the resistance training plus cardio, plus aerobic group. They lost no muscle as well. And in fact, group number three, the resistance training and aerobic training group, not only lost the most fat, they actually gained muscle. So they recomped. And that study is not an anomaly either. It is in line with several other studies in the matter. And the weight of the evidence here is clear. If you want to lose fat as quickly as possible, while also preserving muscle or even gaining muscle, then you really want to be doing resistance training. You can do cardio as well, but you want to make really want to be doing resistance training. You can do
Starting point is 00:08:45 cardio as well, but you want to make sure that you're doing resistance training. And I would say that if you only had time for one or the other, go with resistance training over cardio because resistance training workouts burn quite a few calories. They are not as ineffective for fat loss as many people think. And especially when you focus on heavy compound weightlifting, because those are the type of workouts that burn the absolute most energy and most stimulate the major muscle groups in your body. So they are the ones that are most conducive to muscle building and strength gain. And just to be specific there by heavy, I mean, working with weights somewhere between 75% and 85% of your one rep max.
Starting point is 00:09:32 So that would be like the eight to 10 rep range at the high end and maybe the four to six rep range at the low end. And in terms of compound exercises, I'm talking about exercises that involve multiple joints, multiple major muscle groups, like the squat, the deadlift, the bench press, the overhead press, as opposed to isolation exercises, which usually only involve one joint and kind of isolate and emphasize just one major muscle group, like the bicep curl or the side lateral raise. So that's it. Short and sweet. If you want to maximize fat loss and maximize muscle preservation and even muscle gain then you want to be doing a few hours of heavy resistance training per week anywhere from three to five hours depending on various things your personal circumstances your
Starting point is 00:10:18 ultimate goals your training history blah blah blah but let's just say a few hours of heavy compound weight lifting per week in terms of, I recommend no more than two hours per week if you're doing high intensity interval training. And I recommend that you separate those into shorter workouts. So 20, 25 minute HIIT workouts, no more than two hours of HIIT per week. And if you're just walking, you can get away with a bit more. You could do probably four or five hours a week of walking with no issues. And lastly, of course, you need to also maintain a fairly aggressive calorie deficit, which is really what drives all of this, of course. And by that, I would say a 20 to 25% deficit.
Starting point is 00:10:55 That's my general recommendation. If you're very overweight, you can get away with a slightly larger deficit, but most of us are going to do best with about a 20 to 25% deficit.
