Jim Fixx, the father of the fitness revolution, is a prime example of someone doing the wrong exercise at the wrong intensity. He started running without changing his diet and without regard to whether running was the right exercise for him. Running was the main activity of his life. He appeared amazingly fit for his age with great muscle tone, especially in his legs. But at 52 he came home from a run, had a heart attack and died.
Since Jim Fixx’s birth information is public I constructed his Chinese Natal Chart. He was of the So-eum (lesser yin) constitution and should not have been doing exercise focused on the lower body. This caused his energy to circulate unevenly so that his upper body was not getting the energy it needed. Plus, he was missing fire, which indicated that his heart was weak. He would have been much better off with a change in diet and exercise for his upper body like swimming or kayaking. He also would have been healthier exercising at a lower intensity.
