This study aims to determine whether there is an effect of circuit training on improving the physical condition of soccer athletes at Northwest Pantar football school. The model in this study is a quasi-experimental with a quantitative approach to one group pretest-posttest design. The instruments in this study were the vertical jump test, sit and reach test, 40 meter run test, agility run test, coordination test, endurance test, leg muscle strength test and abdominal muscle test. The population in this study amounted to 20 athletes, and then all populations were used as subjects in this study. Data analysis in this study used a t-test with a significant level of 5%. The results of this study indicate that there is an effect of circuit training on improving physical condition for soccer athletes at SSB PBL. Thus the hypothesis in the study is accepted. The limitations in this study include time, number of SBB, research subjects and training models that are still single. Keywords Circuit Training, Athletes, SSB, Physical Condition 1.
