Here are ten reasons why I don't do aerobic exercise:

But first, what is aerobic exercise? Any steady state locomotion elevating the heart rate into the zone for twenty minutes or more. The zone is determined by formulas based on age and resting heart rate.

Now, ten reasons why it not only doesn’t work but is a poor use of exercise time:

1. Oxidative Stress
   Which causes a breakdown of tissues. It also predisposes one to cancer and heart attack.

2. Elevated cortisol production
   Which causes a breakdown of muscle tissue and increases fat storage or depot fat. People do aerobics to alleviate stress yet end up creating more stress.

3. Lowered testosterone and HGH levels
   For men, aerobics are a form of chemical castration. Low T-levels are associated with lowered libido, depression, anxiety, increased body fat and decreased muscle tissue. This contributes to muscle-wasting and lowers the basal metabolic rate.

4. Increased appetite and a tendency toward binge eating patterns
   Aerobic exercise makes people hungry!

5. Excessive Muscular Fatigue
   Making it difficult to do other more productive forms of activity. Aerobics creates muscular weakness.

6. Conversion of fast-twitch muscle fibers to slow-twitch
   The loss of fast-twitch muscle fibers contributes to aging and the loss of explosive power and speed. People become slower and slower.

7. Burns a relatively small amount of calories vs. the time spent
   One large meal completely offsets the pitiful amount of calories burned in an hour aerobics session.

8. Overuse injuries to the feet, ankles, and knees from excessive, continual force transmitted throughout the body
   This is exacerbated by over-engineered running shoes which cushion the feet in such a way to create a neural amnesia.

9. Shortening i.e., deformation, of the muscle tissue from repetitive mid-range (partial range) movements
   This creates inflexibility, immobility, and muscle imbalances. Besides being tight, the bodies postural alignment becomes compromised. Aerobics create tight, inflexible bodies that are in chronic pain.

10. Adrenal burnout
    A consequence of the “feel good” neurotransmitters which also stimulate the release of adrenaline. Adrenaline is the fight or flight hormone. Excessive adrenaline creates an addictive response and people going routinely for the so called “high” of running end up with adrenal burnout, e.g., chronic fatigue and depression.

Dr. Kenneth Cooper, the father of aerobic exercise (and the person who coined the term) completely recanted his assertions regarding aerobic exercise. After observing a disproportionate number of his aerobic-enthusiast friends die of cancer and heart disease, he reversed his ideas on the benefits of excessive aerobic exercise. He now claims anything in excess of 20 minutes has greatly diminishing returns. In fact, he's now an advocate of scientific weight training.

In strength and health,
