The researcher conducted a study aimed at identifying the effect of an educational program using zumba step on some physical variables and the level of free sentence performance in modern dance. The researcher used during her procedures the experimental method using the experimental design with two groups, one of them experimental and the other controlling in order to suit the nature of this study. Female students of the third year at the College of Physical Education for Girls, Zagazig University, for the academic year (2019-2020) Then the researcher selected (40) students randomly as a sample for research. They were divided into (15) students for the experimental group, (15) students for the control group, (10) students as a survey sample, and the researcher reached a number of results, the most important of which was the existence of statistically significant differences between the measurement The pre-measurement and the post-measurement of the experimental group on some physical variables where the highest value was (T) (37.77) in the dynamic balance variable, and there are also statistically significant differences between the pre-measurement and the post-measurement of the experimental group in the level of free sentence performance in modern dance, where the value of (T) Her (16.63). ,
