This study aims to recognize the effect of circuit body weight training on the increase in arm muscle endurance energy. This type of research is an experiment with one group pre-test and post-test design. The population in the Sleman badminton athlete research is 24 people. The illustrations in this study amounted to 10 people taken using a purposive sampling procedure. The tool used to measure arm muscle endurance is a 1-minute push-ap test. The procedure for analyzing the information used is a paired sample t-test. The results verified that there was a significant effect of circuit weight training on the increase in arm muscle endurance of badminton athletes from early trials and final tests that were intertwined with an increase by a difference of 9.36, namely from an average score of 29.16 on the pretest to 38.52 on the post test, and strengthened by the results of the t test using an illustrative t test paired with a calculated t value of 6. 799 as well as significance values p 0.000 < 0.05. Until it can be concluded that there is a significant effect of circuit weight training on the increase in endurance of the arm muscles of badminton athletes.
