The purpose of this paper is to preparing complex exercises in a competitive manner to improve some mental processes and ball skills in rhythmic gymnastics among second-stage female students, and identifying the effect of knee exercises in a competitive manner in improving some mental processes and ball skills in rhythmic gymnastics among second-year female students. The researcher used the experimental method because it suits the nature of the research and because the experimental method is characterized by the accuracy of its results compared to other results. The researcher followed the design of the experimental and control group with two pre- and post-tests, that is, measuring two groups before and after the experiment. The difference between the two results for measuring the variable is considered evidence of the effect of the experimental factor. One of the most important results reached by the researcher is that: Complex exercises have a positive effect in improving some mental processes (attention acuity, concentration of attention), compound exercises have a positive effect in developing some basic skills, and using complex exercises within the educational curriculum in the special preparation stage has an effective positive effect in improving the mental processes and basic skills of the research sample. One of the most important recommendations recommended by the researchers is that: Adopting complex exercises within the educational curricula designated for female learners within the rhythmic gymnastics curriculum, and paying attention to complex exercises because they help improve some of the students’ mental processes.
