7 Myths About Cardio Exercises

Oftentimes, we hear that cardio exercise is the solution to fat loss.  But “cardio” is not just “cardio” straight across the board – there are different levels of exertion when it comes to cardio exercise that can aid us in fat loss if we know the proper strategy.

There are many common myths about cardio that could slow you down in your quest to fat loss if you aren’t sure how to differentiate between fact and fiction.

Myth 1: The best way to burn fat is doing a steady level of cardio for at least 45 minutes.

Truth: It may feel easier to just walk a fast pace or jog a comfortable pace for an extended period of time.  When you get off the treadmill, and you can see that you burned 300 calories, it feels great.  BUT what you don’t see is what happens afterwards.  When you perform cardio at a higher intensity and performing it with interval training, your body will actually burn more calories overall throughout the day.  Why?  Your body will burn more calories throughout the day to repair itself after your challenging workout.

Myth 2: You can eat whatever you want as long as you do a lot more cardio.

Truth: You are what you eat!  You can’t eat burgers and fries just because you spent an hour on the treadmill and burned 500 calories.  Why work so hard to burn off 500 calories if you are just going to turn around and eat it back on, if not more?  You must eat more healthfully AND do cardio for overall fat loss.

Myth 3: Carrying or wearing weights while simultaneously performing cardio is a big help to burn more fat.

Truth: The light dumbbells or ankle weights are probably not going to be heavy enough to make that great of an impact to elevate your calorie burn.  Do yourself a favor and hit the weight room – as you build your muscles, you will improve your metabolism and burn more calories while at rest.  To burn more fat while doing cardio, elevate your level of intensity with intervals.

Myth 4: Choose one type of cardio and do it religiously forever if you want to lose fat and experience phenomenal progress and results.

Truth: If you exercise the same muscles with the same type of exercise every single day, your body adapts to that exercise.  Ever hear the term “plateau”?  Your ability to burn fat levels out.  Athletes “cross-train” all the time to help them from burning out.  Changing your exercise routine not only helps you stay interested and motivated, but it also helps your body progress.  It keeps your body challenged, and it also helps you exercise different muscle groups when you change up your routine.  Try running, biking, swimming, stair-climbing, or kick-boxing, and remember to vary the intensity too! 


Myth 5: If you don’t have time to do at least 30 to 45 minutes of cardio, then don’t even bother.

Truth: Granted, if you could do at least 30 to 45 minutes of cardio, you may experience greater health benefits quicker.  However, with that being said, if you only have 15 minutes or 20 minutes to get some cardio in for the day, that’s better than nothing.  When it comes to burning calories and fat, activity (rather than non activity) helps you.  Make the most of the time that you do have.  If you don’t have a large chunk of time to spare for a workout, breaking it up into separate smaller chunks is another option.  For example, if you’re unable to squeeze in a 45 minute workout during any one point of the day, maybe you can squeeze in 20 minutes in the morning and 20 minutes in the evening. 

Myth 6: Eating before a session of cardio is a big no-no if you want to burn fat.

Truth: If you are going to do a steady level of cardio without a lot of intensity, you are probably going to be okay working out on an empty stomach.  This may help your body access its fat stores faster and burn that fat as fuel.  However, if you plan on training for a 10K race and your coach wants you to incorporate sprints in between your 10-minute miles, you are going to need glucose for fuel.  If you don’t eat before this type of cardio session, you’ll end up burning muscle tissue.  You’ll do well eating a small protein and carbohydrate meal about an hour before you hit this high intensity workout.

Myth 7: It’s okay to read or talk on the phone during your cardio exercise.

Truth: Although many of us would like to entertain ourselves to pass the time quicker, if you can actually read or talk on the phone (or do any task that requires concentration) while you are performing cardio, then you are not exerting yourself hard enough.  Your level of intensity should be challenging enough so that you are required to only focus on the task at hand:  your cardio!  What about watching tv?  You are better off concentrating on your movements and paying attention to your form to yield yourself the best results.
