Myths Exposed and Little Known Secrets Revealed

 What do you think of when I mention cardio? An hour-long jog? A long, steady session on the exercise bike? Sweatin’ to the oldies? If it’s any of those things, you’re doing cardio, but you’re not doing smart cardio. There are lots of things you can do to burn calories, but if you’re reading this article, you know that you want the calories you burn to come from fat, not lean mass. Traditional long, slow distance cardio burns muscle and fat pretty indiscriminately. In fact, if you do enough, you may find that your body burns muscle preferentially to ease the demands of doing so much aerobic work. That’s exactly the opposite of what you want.

So how do you do cardio without sacrificing precious muscle? The answer is interval work. Definitely get yourself cleared by a doctor before jumping into intervals, because the whole idea is to rapidly and repeatedly raise your heart rate, alternating the high heart rate work with brief recovery periods. The optimal way to do interval work is probably to do walk back sprints. Sprint all-out for 15 seconds, then turn around and walk back to where you started. It should take about 45 seconds to walk back. Once you’re back where you started, sprint for 15 seconds again. Do seven sprints your first week, and add one sprint per week until you’re up to 20 sprints per session. If you’re not up for sprints, you can approximate them on an exercycle or an elliptical machine. Simply go all-out for 15 seconds, then pedal or walk at a recovery pace for 45. The same build-up pattern applies.

In order to grasp this concept, you must first learn what your body burns for energy during strenuous exercise.  I call this energy body burn, “The Hierarchy Scale Of Energy.”  The human body accesses certain nutrients for energy and does so in a precise manner every time.  This access order NEVER changes.  Let me repeat, NEVER changes.  This scale will alter the way you train forever!  Here it is.

 

   1. MUSCLE GLYCOGEN

(Sugar processed from carbohydrates and stored in muscle for contraction)

   2. LIVER GLYCOGEN

(Storage organ for excess glycogen; primary fuel source for brain function)

   3. BBA (BLOOD BORNE AMINO ACIDS)

(Branched Chain Amino Acids formed from protein)



4. FAT (Speaks for itself)

 

 ¨Notice where FAT is on the scale.  It is last!!!  It’s the one thing we hate the most about our body and it’s the one thing your body hates to give up.  The irony! 

 ¨It takes between 20-30 minutes to reach level #4, depending on the time of day you train and when you last ingested carbohydrates.

 

   Case#1: Come into the gym and jump on the cardio machine (pick your favorite).  Remember it will take 20-30 minutes to burn the muscle glycogen, liver glycogen and BBA before you reach fat.  In reality, the first 25 minutes of cardio is totally USELESS!! That is of course unless you actually enjoy doing cardio, simply for the love of doing cardio.  If you do, then I will affectionately call you NUTS!  Most people do it for fat loss, so why not make it the most effective?  To access fat, you now have to add an additional 20 minutes of cardio to get any results.  The entire cardio session alone will be around 45 minutes. Now you go to weight training.  But wait, where is your muscle glycogen (fuel for muscle contraction?) Right, it’s gone!  The result; weaker workout, less muscle development, increased fatigue, over training, burnout, longer recovery and a slower metabolism.  In short, NO PROGRESS!  You get discouraged and quit training because your body is not changing.

 

   Case #2: Come into the gym and you jump on the cardio machine for 5-minutes to warm-up. Now you hit the weights.  Where is your muscle glycogen?  Right, ready to go for power and intensity resistance training.  Train for 30 minutes with weights and use up #1-3 on the Hierarchy Scale.  Result; increased strength, more lean muscle, less fatigue, no burnout, more intensity. Now begin cardio training.  What is the only available energy source left to burn for the cardio session since #1-3 are gone?  You got it, #4!!  Now you access fat stores immediately and only have to do 15-20 minutes of cardio to get the same benefits as 45 minutes in Case #1.  That means more fat loss! In short, PHENOMENAL PROGRESS!  You get psyched and train harder.

Which would you choose to do? I know my answer!

Everyone has wondered at some point in time which cardio exercise is better. To put it in simple terms, both low and high intensity exercises will help you to burn off body fat. The question here is which is the most effective to burn off more body fat.

When scientists first discovered that during intensive exercises, your body burns glycogen, which is a form of stored carbohydrates that are stored in your liver and muscles for energy. During low intensity exercises, your body will burn a lot of fat.

If your wondering whether or not it works, the answer is no because there are so many obese people still around. Even though they are working out with low intensity routines, it still makes you wonder how it can be.

The scientists were right when they said the human body burns more body fat during low intensity exercises like walking or swimming. During a high intensity exercise such as running, the body will burn a lot more calories. Even if some of the calories burnt are from glycogen, there are still many fat calories burned as well.

To put the icing on the cake, when your store of glycogen gets low, the carbohydrates from your food you eat will later get converted into glycogen to fill up the store and won’t be converted to body fat when they are left unused for energy.

High intensity cardio exercise will juice up your metabolism even after you have completed your workout. What this means, is that your body will continue to burn body fat hours after you have left the gym. This effect is nearly non existent in low intensity cardio or aerobic workout.

Accumulatively, your body will burn up more and more calories during and after you have finished a high intensity cardio exercise that it will with low intensity.

You can inject high intensity exercises into your cardio workout by introducing some interval training. You can walk for 5 minutes or so, then break into some jogging for another 5 minutes or so. Then, walk briskly again until you have caught your breath and then sprint for a minute before you walk again. From this point, simply alternate your running and walking for the next 15 minutes until you are finished.

One of the best things about cardio is the more you do it, the more energy you’ll have. Cardio will help you to burn calories, although its more useful for keeping your energy levels high.

If you’ve never tried cardio before, you should give it a shot. If you like to exercise, you’ll find cardio the best way to boost your energy and keep in top shape. If you are just starting out, you’ll want to go slow and keep your cardio exercise in track – as it is very easy to over exert yourself.
