In fact, the fitness effect of practicing yoga is also very good, but many people have not invested in it and deeply realized the true charm of yoga. As for why "pulling the Three Classics" and yoga are more effective than fitness, the reason is the difference between "static" and "dynamic".
When pulling the third warp, lift your legs into the air and pull them apart and fix them with lacing tape. At this time, qi and blood flow to the abdomen, chest and head under the action of gravity, and more nutrients flood into meridians and every cell. At the same time, qi and blood impact the focus, dredge meridians and activate dying cells and tissues, just like withered plants naturally glow when they meet water. This is why some bosses like to put their legs on the table. Actually, it's not arrogance. At this time, the blood in their legs above their heads will quickly flow to their bodies and brains, and they will feel very comfortable and tired. This is also the reason for the rapid fitness of "pulling the Three Classics".
The key and important mechanism of all this is that it all happens in a "static state". Just like a straight water pipe, water keeps flowing, clearly, even if there is residue on the pipe wall, it will be washed away. Yoga is very slow, but it is always in motion. As soon as the meridians are pulled, they are relaxed and opened, and the flow of qi and blood slowly turns, just like when a straight water pipe is bent, even if the water flow is large, it will not flow smoothly. Therefore, it takes a long time to practice yoga to achieve good fitness results.
Of course, practicing yoga is not the same as the popular yoga at present. Real yogis also need to lay a good foundation, such as stretching tendons at rest. It takes a long time for a posture to get up, which is similar to the static state of "La San Jing" but not exactly the same. "Pulling the Three Meridians" is to pull the legs by gravity and in a continuous and static way, so that qi and blood can be injected into the body and head, the meridians can be activated, and nutrition can be provided for the cells of the whole body, thus achieving the purpose of rapid fitness.
