Running, in addition to the core strength of the tablet to support the exercise, the need for more muscle involvement. If the human body as a whole, running in the muscles involved in addition to the waist and abdomen, hip and thigh, hip and thigh and other muscles to pull the hip, to maintain stability. In my own case, at the front of the thigh of the posterior leg muscles is relatively developed, and often rides a bike to strengthen, and causes muscle compensation. That is to say the two parts of the muscle in running excessive force to replace part of the role of gluteus medius muscle and thigh muscle of the side after.
Since it is compensatory, destined to pose can not be accurate, and even increase the risk of injury. Like leg tibial knee and other parts of the injury and muscle imbalance, can not provide the corresponding support. If you keep running, the weaker side of the muscles will only become weaker and weaker. O type X leg is also a high risk of running injury leg type. It is worth to be happy, and now the professional fitness running a lot of science, for all kinds of problems have the corresponding training programs, patience will always find.
In addition to the muscles that can be seen, running also requires an awareness of the body. There is no muscle strength, joints can be active, what can come out. And the consciousness of noumenon is a kind of conscious or unconscious feeling of body space position.
