The physical practice of asana works on the body using contraction, stretching, compression, and release of the soft tissues to create openness and evenness. These actions increase tissue circulation just as the opening of a dam sends rushing waters into smaller waterways. Areas of the body once stagnant and starting to deteriorate are flushed out by this action; they then start to receive nourishment and function fully. The increased number of cells in the body boosts the amount of energy produced while decreasing the workload on the organ systems, allowing them to perform at optimum levels, and balancing hormones and metabolism.
Increased flexibility - Yoga has positions that act upon the various joints of the body including those joints that are never really on the 'radar screen' let alone exercised..increasing lubrication of the joints, ligaments and tendons: Likewise, the well-researched yoga positions exercise the different tendons and ligaments of the body. Surprisingly it has been found that the body which may have been quite rigid starts experiencing an extraordinary flexibility in even those parts which have not been consciously worked upon. Why? It is here that the remarkable research behind yoga positions proves its mettle. Seemingly unrelated "non strenuous" yoga positions act upon certain parts of the body in an interrelated manner. When done together, they work in harmony to create a situation where flexibility is attained relatively easily.
Massaging of ALL organs of the body - Yoga is perhaps the only form of activity which massages all the internal glands and organs of the body in a thorough manner, including those (such as the prostate) that hardly get externally stimulated during our entire lifetime. Yoga acts in a wholesome manner on the various body parts. This stimulation and massage of the organs in turn benefits us by keeping away disease and providing a forewarning at the first possible instance of a likely onset of disease or disorder.
Complete detoxification - By gently stretching muscles and joints as well as massaging the various organs, yoga ensures the optimum blood supply to various parts of the body. This helps in the flushing out of toxins from every nook and cranny as well as providing nourishment up to the last point. This leads to benefits such as delayed ageing, energy and a remarkable zest for life.
Excellent toning of the muscles - Muscles that have become flaccid, weak or slothy are stimulated repeatedly to shed excess flab and flaccidity.
