Softness vs. Flexibility

For most people looseness and softness will add more ease to ones normal daily life than flexibility will; activities like brushing one's teeth, picking up children, riding a bike, and getting into a good seat at the movies when we arrive after the lights have gone down.
Some people may be thinking, "my muscles are already too soft."  This, however, is unlikely to be the case for anyone who has even a mildly active life. What is more likely is that there are parts of one's body that are very soft and other parts which are rigid- a muscle imbalance problem not a softness problem. Softness is a problem when paired with rigidity or when there is so much deficiency in the underlying structure that the muscles no longer function. The development of true strength is aided by softness and built on underlying structure. (What we sometimes call jing.)
