The purpose of this paper is to preparing applied boxing exercises on two rings of different sizes for young boxers, and identify the effect of applied boxing exercises on two rings of different sizes in developing the performance level of side and upward punches for young boxers. The researcher used the experimental method by designing two equal groups (experimental and control). The research community was defined by young boxers from the clubs of Wasit Governorate, whose ages do not exceed 16-18 years and each weighing (51-54-57) kg. They numbered (34) boxers. (10) boxers were excluded for the purposes of the exploratory experiment, and the research sample was selected using the method Simple randomization, so the total number of boxers reached (24) and they were divided into two equal groups (12 boxers for the control group and (12) boxers for the experimental group. The experimental group undergoes training prepared by the researcher, while the control group continues with the coach’s training curriculum. The sample percentage was from the indigenous community (70.58%). The sample is considered homogeneous in the variables of age, weight, and training age, as the boxers are all of the same age group (youth) and the weights are almost similar in the control and experimental groups. One of the most important results reached by the researcher is that: The use of applied boxing exercises on two rings of different sizes had a positive impact on developing the level of performance of side and upward punches, and training boxers in small rings with an area smaller than the area of a legal ring is of great benefit to the boxers in developing the skills of side and upward punches.
