CARDIO KILLS?
Let’s Define Cardio;
Low Intensity Long Durational Cardio (aerobic – needing oxygen to supply energy) (heart rate is between 50-65 % of your maximum) aka jogging for 60-90 minutes
When you do this type of cardio work, your body gets the majority of energy it needs from fat.
Interval Cardio (anaerobic, not needing oxygen to supply energy) (heart rate is between 90-100% of your maximum) Four to six challenges that are 60 – 90 second bursts of exercise with rest periods in between. Each progressive challenge is incrementally more intense than the last. As each challenge becomes more intense, the rest periods become longer. The goal is to be totally recovered and ready for each challenge. Example; the 100 yard sprints that you used to run for football practice.
When you do this type of cardio work, your body gets the majority of energy it needs from glucose (blood sugar) and from glycogen stored in the muscles & liver, and from ATP and creatine.
Glucose & Glycogen are like gasoline (fuel) that your motor (muscles) uses to perform.
Your body takes the carbs that you eat and breaks them down into glucose & glycogen.
The common myth that jogging is better for fat loss, fitness, & health is a strong one that is wrong;
The old school text books & simple minds say; “To burn fat, you must stay in the fat burning zone (heart rate between 50-65%) for 60-70 minutes. You don’t start burning fat until about 20 minutes into the work-out. So if you do a 70 minute session, you will get 50 minutes of fat burning.
I am going to clear this up for you once and for all. You see for fat loss, it is not about where your body gets the energy from the work-out for (slow go cardio / fat, interval / glycogen) nearly as much as it is total calories.
You see the instant that you are done with low intensity jogging; your body is done burning calories. But, do an intense set of intervals, and your body burns calories for the 2-4 hours after the work-out. So the total amount of calories burned form intense interval far exceeds that of jogging type cardio.
Another big advantage that you get with interval cardio that most do not know about is that it changes the way your body stores your calories in the future: and in a very good way. You see most of the benefits of exercise come after the exercise are completed. It is how the body adapts and changes. Tear down muscles by weight lifting, and in the 1-2 days after, the body repairs the tiny micro tears back so they are a little bigger & stronger.
Well cardio is much the same way. When you do low intensity jogging type cardio, your body says, “It’s a good thing I had that fat there to supply energy for that work out”. So it makes sure that it has plenty of fat there in preparation for the next “slow go cardio” session.
But when you do intense intervals, your body says, “It’s a good thing I had that glycogen in the muscles for that interval cardio”. So when it breaks down your future meals, it stores more of the carbs as glycogen in the muscles and the liver in preparation for the future “Interval Cardio” sessions. In essence, your gas tanks enlarge with useful energy. This is great for at least two reasons.
- You will have more readily available quick burning fuel (glycogen). Which means you can have more quick usable energy to do intense activities.
- Glycogen burns energy just sitting there it raises your BMR (basal metabolic rate). The more muscle and the bigger your glycogen gas tanks are, the more calories you will burn while you are just sitting or sleeping. That is a great thing. It is just like the difference between muscle & fat.
In fact, I believe that traditional CARDIO KILLS;
- Your time
- Your immune system
- Your joints
- Your body composition
Traditional Cardio kills your time. You have to do hours upon hours to see results. The only way to progress is by going farther; which takes more time. Eventually, if you want to keep progressing, you are going to run out of time.
Traditional Cardio kills your immune system. When anyone uses traditional cardio 2 or 3 times per week, carcinogens are released. A ground breaking study of long-distance runners showed that after a workout, the blood levels and oxidation of LDL (bad) cholesterol & triglycerides increased. They also found that prolonged running disrupted the balance of blood thinners and thickeners, elevating inflammatory factors and clotting levels—both signs of heart distress.
Traditional Cardio kills your joints. No one has perfect symmetry with their bones, tendons, ligaments, flexibility, range of motion, strength, etc. When you repetitiously do the same thing (jogging stride) over and over again, the pounding of the pavement puts stress in bad places. Consistent pounding of the body from traditional forms of cardio lead to severe injuries in your back, knees, ankles & everywhere in between. Just take a look at the Chicago marathon; ¾ of the runners have on knee braces.
Traditional Cardio kills your body composition. Cardio does nothing to improve your lean muscle to fat ratio. In fact, most marathon runners lose muscle. Look at the difference between the physiques of an elite marathon runner and an elite sprinter. Which physique do you want? Then train like a sprinter. He does sprints. Most marathoners go into a starvation mode; the body becomes catabolic, and burns muscle for fuel. Best case scenario, is a cardio hound that starts out like a pear shape, ends up a smaller pair shape. Not my idea of progress.
