TAC TIC ELBOW
The TAC TIC aids give the player and coach valuable information.
Feel how the elbow remains half-bent in the preparation of a forehand.
Hearing aid by means of a metal piece inserted in a joint protector, to improve the impact technically: the metal piece "clicks" when the joint is bent.
If the piece sounds at the right moment, it indicates that the technique used has been the correct one. It includes a guide for use by blows and suggestions for each product.
