I have been practicing the master routines for over a year now, with great satisfaction. I bought the heart routine for my girlfriend as a Christmas present, and I had heard so many good things about the Heart Course from my classmates that I decided to buy it because of the estrogen deficiency caused by menopause and the chance of cardiovascular problems resulting from it, which according to Western medicine is inevitable without medication. I knew that this would be excellent, just like the other courses created by Master Zidong. It consists of interesting, useful and easy exercises. Master Zidong, as an excellent teacher, gives detailed explanations for each exercise, as well as a demonstration video so that we can practice together. The Master always shoots his videos in breathtakingly beautiful locations so that we can relax in the beauty of nature. The exercises are not strenuous, but they thoroughly rev up our blood circulation, we feel the energy flow in our body, while our mind calms down, without sedatives or other medications! The stress and anxiety-relieving effect of the course was extremely convincing for me, by the time I finished the exercises, an indescribable calm, peace and love filled my heart. I use this beautiful course for prevention. I can handle the load well on hills and stairs, I move easily and without fatigue like young people. This much better endurance compared to my age is also reflected in everyday things. My body loves and needs movement. Master Zidong's excellent professional courses are the best for this. I recommend the heart cure to patients and those who want to prevent cardiovascular problems in time. You can quickly fall in love with it. Thank you very much, dear Master, for the invaluable courses. 🙏🥰
