Since the1970's, "aerobic" exercise and "cardio" training have been taught as the way to burn fat, but is it a true statement?
If you look at the science and real world results, the answer is a resounding, NO!
The first part of this error lies in believing that the body changes while you exercise, which is simply not true. You provide the body with a stimuli while you train. Then, while you recover your body uses that stimuli to create your adaptation. So, let's look at what cardio and aerobic work does.
The first part of your training is fueled by ATP (Adenosine triphosphate). Then, after you've burned through your ATP your glycogen stores kick in to fuel the next part of your workout. After that, once you've burned through both of those, body fat kicks in to fuel your work. And this is where the misconception starts.
To make the math easier let's say that it takes you 30 minutes to burn through your ATP and your glycogen. This means that if you exercise for 45 minutes, you've only touched your body fat for 15 minutes of fuel. Still with me? Good.
This is where most people think, "Holy Hell, if I train for 45 minutes and only burn 15 minutes of body fat I better train longer. I better do an hour of jogging/cycling/spinning so I can at least get 30 minutes of fat burning to happen. And this would be true if you're body changed while you were training. But it doesn't.
Your body trains while you recover.
So, let's say that you've spent the past few weeks doing an hour long spin class 5 days a week. What is the stimuli that you're body is adapting to?
Your body is saying, "shit, we're doing "cardio/aerobic" training five times a week for 60 minutes at a time. This means that I need to store at least 30 minutes worth of body fat so I'll have the energy to continue riding that damn bike. Since I like to super-compensate though, I'll make sure to store enough body fat to fuel at least 60 minutes worth."
In other words, you actually are training your body to store body fat for fuel.
So, if you're training your body to store fat for fuel, are you burning body fat and getting lean>
No!
This is part of the reason why you'll see so many people that have lost a ton of weight that just look like smaller versions of their fatter selves. Because they are simply smaller versions of their fatter selves.
By embarking on the "cardio/aerobic" path you train your body to store fat for fuel while at the same time eating up your precious muscle tissue (not just your abs and pecs either, but the muscle from your heart and lungs as well), and you stop the production of good fat burning hormones such as Growth Hormone and Testosterone.
In other words, if you want to get lean and have your weight loss be from fat, ditch the "aerobics" and opt for strength training and sprinting. You'll thank me when you see yourself in the mirror.
Yours in strength,
