Swing / Gravity

Gravity is a natural force that influences the motion.

Swing is the use of force in its maximum expression.

It is the duality of gravity vs swing which enables a child, which of course has little muscle mass, may have very effective moves and good speed.  

   This relationship will be the first principles of movement, the student will experience in the early stages of learning and this is only possible with the body relaxed, eliminating unnecessary tension.
    In this first phase the student will have to be aware that performs the motions predominantly technical with joints and not with muscle strength, whether child or adult.
    The exercise that runs the technical movement holding the racket with only three fingers is fantastic to get the awareness of "swing" and "gravity", it is a right, left or service.
