The basic positions a person normally takes up in most of his/her life are sitting and standing,where the body weight is passed on to the supporting plane directly through the middle part of the body or the legs,and the supporting plane in turn transmits or disperses the counterforce,again via the middle part.In this way the middle part serves as a connecting link.Normally,the middle part bears the heaviest load in a person's life,whether in a standing position or in a sitting one.Consequently,exercising this part merits the same amount of attention as that of exercising other parts or systems.Also,the article introduces some basic methods of building strength for increasing the flexibility of the middle part.
