Background. Explosiveness in volleyball smash skills is crucial because maximum power is needed when making a smash shot, and the arm muscles are maximized. Objectives. This study aims to analyze (1) the effect of medicine ball throw and bench press exercises on increasing the arm muscle power of volleyball athletes and (2) the difference in the effect of medicine ball throw and bench press exercises on the increase of arm muscle power of volleyball athletes. Methods. This type of research is an experiment with one group pretest and post-test design. The sample in this study amounted to 80 athletes who were taken using random sampling techniques. The instrument used measures the arm muscles' power, namely the test medicine ball put. Results. The study's results showed that: 1) medicine ball throw training and bench press training significantly increased arm muscle power with a significance value of less than 0.05 (p<0.05). 2) There was a significant difference in the influence between the group given medicine ball slam training and bench press training on increased arm muscle power. It was proven that the average value of arm muscle power in the group of athletes who were given medicine ball throw training was 6.80, while the average value of arm muscle power in the bench press exercise group was 2.70 with an average difference of 4.10 post-test. Conclusions. The volleyball athletes given medicine ball throw training had better arm muscle power than the bench press training group. © 2025, Society of Aging and Physical Activity (SAPA).
