In search of the Ideal Aerobics routine?

“6 to 8 very hard 20 second intervals with 10 second rest periods may be one of the best possible training protocols….” Izumi Tabata, Ph.D., National Institute of Health & Nutrition, Tokyo, Japan

Why does this very short interval workout work so well?
Why does this protocol substantially improve both aerobic and anaerobic capacity?
Why is that a surprise?
Is there a lesson in this for bodybuilders and others interested in both strength and endurance?

Overload and Specificity

The answers to these questions lie mainly in the principles of overload and specificity. The overload principle says that training adaptations come about when the body is subjected to unaccustomed stress. Specificity says the adaptation depends on the nature of the overload imposed.

In other words, specific exercise overload brings about specific training effects.

This type of training supercharges the fat burning process for hours after you leave the gym!
