cardio-jogging-2We’ve all heard the science.  And we all know science doesn’t lie, right?  Well on this one there is definitely some gray area.  And more importantly, some human emotion and physiology that plays here.

So, we have heard the argument…

Is it really worth it to grind on the treadmill for 20 minutes?  You only burn 250 calories, which is one cookie!  Now some people really enjoy doing cardio.  They actually look forward to that 30 minutes of grind and hustle.  But if you’re like most people, you would probably prefer to be taking it easy, or better yet, eating that cookie.

So is it really worth it?  Why not just eat 250 calories less on your cardio days and avoid all the hassle!  Makes sense, right?  If the science is right, it’s all about calories burned vs calories consumed.  And yes, the science is right, but there is more to this story.

First, when you do your cardio, there is just something on the inside that affects you and your mentality.  It is hard to put into words, and is most certainly sub-conscious.  But you will see the effects on the scale.  It is like magic.  Subconsciously you will be wired to practice better habits.  It is almost like your insides are telling your brain “Hey, we did that jog this morning for 20 minutes and it sucked, so let’s not throw that away at lunchtime!”

Do a test run for yourself, and you will see that somehow the science is off on this one.


Start on a Monday morning by weighing in, and then go thru your week eating your basal metabolic rate calorie count (BMR).  And do no cardio.  Weigh yourself on Friday morning, and record that weight.

The next week, do the same routine, except this time eat a few hundred calories over your BMR, but also do 20 minutes of good cardio.  Then weigh-in on Friday morning and compare the numbers.  Now, there are other factors at play here, such as how much walking you do during the normal course of the day in each week, etc.  But all other things being equal you will no doubt yield better results during the week you do cardio.  I have seen this time and again.  It is part mental, part physiological, part sub-conscious, part whatever…it just happens!  Guaranteed.

When you incorporate regular cardio into your lifestyle and your routine, you will improve your weight, your fitness, and your overall health.  That really is the science.
