In this modern era, Pencak silat is not only for art but also competed to find the best athletes. Through this study, researchers tried to apply a treatment method of weight training using resistance bands which is expected to increase leg muscle strength in pencak silat athletes at the SPDKK Deli Serdang College. This research uses pre-experiment method, which is a type of quantitative research. The design used in this research is One Groups Pretest – Post-test Design. The population in this study were athletes of pencak silat perguruan SPDKK Deli Serdang totaling 30 athletes, the samples in this study taken were athletes in the sparring category aged 12-15 years. The test instrument that will be used to measure the initial test (Pre-test) and the final test (Post-test) uses the Standing Broad Jump Test. The results of the research data analysis showed that the experimental group studied experienced a significant increase. The results of pretest data based on measurement test data at the time of the pretest found the results of descriptive analysis of the maximum value of 48 minimum 30, average 39.23 and standard deviation 4.688. While the results of post-test data research are based on data obtained from post-test measurement test results. The results of descriptive analysis found a maximum value of 55, a minimum value of 37, an average value of 46.00, and a standard deviation value of 4.934. So thus from the results of this study it is proven that the provision of training programs using resistance band media can have an effect on increasing the athlete's leg power.
