1. Aerobic Exercise Is Bunkum

Aerobic exercise means consistent, endurance exercise, such as running, walking, rowing, jogging or cycling. We are constantly, repeatedly recommended to get 30 minutes of this 5 times a week.

There is a reason for this: it is that **people who do much less than this amount die sooner**.

However, that does not make it right.

That's a bit like saying: "People who eat 6 bacon sandwiches a day die sooner than those who eat one bacon sandwich as day. Therefore, government advice is to eat one bacon sandwich a day."

There is plenty of evidence to show that aerobic exercise:

• Increases LDL (unhealthy) in the blood - leading to more cholesterol deposits
• Increases triglycerides - that is, the amount of fat kept in the blood - bad news
• Increases c-reactive protein (CRP), a known risk factor for heart disease and cancer (see this article on CRP and inflammation)
• Reduces bone density

(Reference: Dr Al Sears, Rediscover Your Native Fitness, Page 9)

The main trouble with aerobic exercise is that you get used to it.

After a few sessions the body thinks: "Ah - this person wants the muscles to be ready for long periods of moderate exercise. I will make my muscles more compact to get ready for this."

The results is a smaller (and less healthy) heart and smaller (and less healthy) lungs.

The best sort of exercise does not allow your body to get used to it; it keeps changing. *Interval training* meets this requirement. I cover this later.
