The oxygen-efficient aerobic exercise mentioned in this book is very simple.

Oxygen-efficient aerobic exercise can add flexibility to our lives, increase energy, and improve our attitude. It can also elevate the awareness of our physical and spiritual beings.

One time, I was on a train station platform, I saw a old gentleman fall to the ground. At the time, his face was pale, his breathing was weak and interrupted, in other words, he was at the brink of death. Immediately, I performed the oxygen-efficient aerobic exercise (lifting and moving his feet left and right repetitively) on him for about twenty to thirty minutes. The result was that he blew out a big breath. His face was turning red, and I was certain then that he came back to life. A moment later, he thanked me profusely with tears in his eyes. I had two experiences like this. In both incidents, they all came back to life in a very short time.

When I did short lectures on oxygen-efficient aerobic exercise, the audience could only understand the superficial part of the theory and not the details. With over forty years of experience in medical health study and research, I have so much detail about the theory and the phenomenal effects of oxygen-efficient aerobic exercise that I could only put them in a book. Oxygen-efficient aerobic exercise is the most suitable exercise that we can have. I am very happy that I have the opportunity to introduce the essence and details of oxygen-efficient aerobic exercise through this book.
