Is Cardio REALLY Necessary for Fat Loss?

Let me begin by saying that I am a firm believer in exercising however I rather lift weights and do strength workouts than cardio type workouts. When I lift weights I feel that my heart rate increases...so that should equal cardio?!?!! Right? I do the cardio because I've heard just like many others that you need it for fat loss. I'm not to sure about that...perhaps I should do some research on it. I do know that my female cousin lost about 60lbs just weight lifting and eating right. Since I actually enjoy strength training I think I'm going to up that to 3-4 times/week and focus on cardio for 2 days/week.

What are your thoughts? Has anyone lost weight with just strength training? I'm very curious about this.

    90% of your weight loss will come from your diet. Exercise is for fitness and that fitness can be whatever you want it to be. If you want cardio fitness you'll need to do something like running, if you want muscular fitness then do lifting.

    Truth. You don't actually *have* to exercise if you goal is simply weight loss. Your diet is of upmost importance. For fitness, and to minimize muscle loss, it's optimal to do both cardio and strength training.

    I agree. Though, I have heard that HRM aren't as accurate when it comes to calories burned for weight lifting. Just something to think about.

    I agree that what you eat is the key for weight loss. Exercise of any kind can only help.

    It's funny found your post...the ladies on Eat More 2 Weigh Less posted a link to this article written by the wife of the author of "New Rules of Weight Lifiting"
    It's about how she shifted from weight lifting to training for a triathalon and got "soft" and gaind fat...lost muscle. It is very interesting. Give it a read

    From the multitude of posts I've read and all the success stories I've seen your plan sounds good. A lot of people lose weight (and muscle) by lots of cardio and a calorie deficit but end up skinny fat. For a sleek toned body you want to lift weights to retain/build any possible muscle mass throughout the process.

    The more you enjoy doing something the more likely you are to stick to it too! Good luck on your journey.

    You can definitely lose weight by just doing weights. I don't think a little cardio would hurt though. Why don't you try doing HIIT? It's basically weight training with short cardio bursts.

    I am not including cardio in this cut, just weights five days a week (usual routine) and eating 250 calories below my TDEE. My progress is fine as I am about 5 lbs away from my goal.

    ^^^THIS! HIIT actually burns more cals anyways...and burns it in the right way so you can keep your lean sexy muscles. And the more muscle you have the more fat your burn ;)

    Oh puh-leeeze! What was she eating while training? Scarfing down donuts or something? Have you actually watched an Ironman race? Athletes who train for an Ironman are some of the fittest around. Seen pictures of them? They look pretty cut and defined to me. I've done a half-ironman, and I have never looked better than when I was training for one. My back and arms were cut, defined and strong from the swimming, my butt, abs and core and not to mention legs were slim but strong and again, defined, from the running and cycling, and my body fat dipped into the low teens.

    To the OP - weight loss is 80% diet. Cardio helps your heart and keeps it healthy. So although cardio may not be necessary for fat loss, in my view, it is necessary to live a healthy life.

    ETA: btw I do not lift a single weight and I think I look pretty damn ok for doing cardio only.
  • I hate using the word cardio, any successful workout should get your heart rate up. There are two main types of exercises "aerobic" and "anaerobic". In aerobic exercises, the muscle is twitching so fast (like in running), that the body doesn't have time to supply enough energy to complete the task, so it uses oxygen until it can supply enough energy. Oxygen burns fat. Aerobic exercise is a fast way to lose fat, but its effects don't last very long so you have to do it almost everyday. Anaerobic exercise happens when the muscles are twitching so slowly (weight lifting) that the body has enough time to utilize ATP as its energy source. Anaerobic exercise builds strength and stamina, and ultimately speeds up metabolic rate. The downside is that in order to build muscle, we have to put small tears in the muscle, allow for repair, and then to become bigger. Done correctly, this takes time, but the effects last longer than aerobic.
    The reason why aerobic exercise is important, is that the body likes to find the easiest and quickest way to utilize energy. Eventually your body will adjust to your weight lifting routine and the fat loss will become less effective if any at all (be more maintenance). On days where you might not be weight lifting, or you are had a light lifting day, include about 30 mins of aerobic exercise. Another good idea, although this applies more to aerobic exercise than anaerobic exercise, is to break your workout up into 2 or 3 mini workouts. This refers back to the simple physics law "an object at rest tends to stay at rest and an object in motion tends to stay in motion unless acted upon by an outside force". The object is your body, the outside force is energy. If you break your workout up into 2 or 3 mini workouts, your body will have to utilize more energy to go from resting to working a couple different times, vs if you completed the workout in one session.
    As mentioned previously if you're trying to lose fat, no matter how much you exercise, if you have a ineffective diet then you will see little to no results. Let me explain what I mean by ineffective diet. You need to eat healthy, obviously, but depending on your exercise you need to use the energy source that would be most effective for your body. There are three main types of energy sources: carbohydrates, fats, and protein. Carbohydrates are your body's favorite, they are easily utilized as an energy source. This is great when you're doing a lot of aerobic exercise and you need your body to create energy faster. Like I said before, the effects of aerobic exercise don't last as long and so to see results you would have to perform a aerobic exercise everyday. For anaerobic exercising, such as weight lifting, it is better to have a diet high in fat and protein, and few carbohydrates. Fat is the second easiest source of energy for your body to utilize, it also contains twice the amount of energy compared to a protein or a carbohydrate. You need to make sure you eat saturated fats, not unsaturated, you want your body to work for its energy. By eating saturated fats, you will utilize more energy AND train your body to burn fat (which is what you want, fat loss). This is one reason why the Atkins is so successful. Proteins are the hardest for your body to breakdown. The reasoning behind this is once again your body is lazy. Your body will first try to use carbohydrates, then fat, and finally protein as an energy source. This is necessary because our bodies are made up almost entirely of proteins. Im sure you know this, but the reason it's important to have a lot of protein in your diet when performing anaerobic exercise is because protein is necessary to build muscle. You need to make sure that you stay hydrated with WATER (not sugary drinks, kind of defeats the purpose), because the breakdown of proteins creates a lot of toxic waste and your kidneys need to use a lot of water to flush it from your system. If you don't, then you could injure your kidneys.

    No.

    You don't have to do any cardio at all. However, the strength training you like to do is very good for muscle retention on a cut.

    alexamae5 - this may be the single BEST response to this question ever!!! Thanks for sharing this. Makes me realize that I NEED to rethink my workout strategy. Perhaps hiring a trainer for a session or two would be most beneficial. Anyway... thanks for your post!
