The The aim of this research is to designing a training program thru core stability exercises and observes the effect of this suggested program on dynamic balance, some physical and skills variables for Table Tennis players, the researcher used the experimental method for the one experimental group. The research sample was been selected from players of the Alnasr sporting club in Oman. The sample of the research was (5) players, the researcher applied physical and skills abilities tests after that he applied the training program using core stability exercises for (10) weeks, then he performed measurements on Dynamic balance, some physical and skills variables test.  The results revealed that there were statistical differences between the Pre-measurement, Tracer- measurement, and the post-measurement regards variables Dynamic balance, some physical and skills variables the researcher recommended using the core stability exercises over the preparation period.
