What is the point of holding difficult postures?
If one tries to stretch and twist the body, the tension spots are easily revealed as they will be the main obstacles to flexibility. Also, the tension spots will be exposed by maintaining the same posture for extended periods of time since tension will require extra energy and the tension spot will be the first tired spot. Just like dirt in the water can only be noticed when the water is still, so are the blockages. That is why although moving exercise is important for learning how to maintain the connection and relaxation, the still exercises are very valuable. The other effect of still exercise is rapid accumulation of energy. The methods range from aggressive methods of Yoga to balanced methods of Taoist Qigong to mind over body (almost ignoring the direct physical training) methods of Buddhist Qigong.
