This study aims to analyze: (1) The effect of complex training methods and circuit body weight training on increasing leg muscle power and arm muscle strength of basketball athletes and (2) the difference in the influence between complex training methods and circuit body weight training on increasing leg muscle power and arm muscle strength of basketball athletes. This type of research is an experiment with the design of two groups pre-test and post-test. The sample in this study amounted to 70 athletes taken using random sampling techniques. The subjects were divided into 2 groups of athletes, namely the group given the complex training method of as many as 35 athletes and the group of athletes given the circuit bodyweight training method of as many as 35 athletes. The instruments used are to measure leg muscle power, namely the vertical jump test, and to measure hand muscle strength using an expanding dynamometer. The data analysis technique used is an independent sample t-test followed by a paired sample t-test. The results showed that: 1) There was a significant effect of complex training methods and circuit body weight training on increasing leg muscle power and arm muscle strength of basketball athletes with a significance value smaller than 0.05 (p < 0.05). 2) There is a significant difference in influence between the groups given the complex training method and circuit body weight training on increasing leg muscle power and arm muscle strength of basketball athletes, it is proven that the average value of leg muscle power in the athlete group given the complex training method is 143.5 kg/sec while the average value of leg muscle power in the circuit body weigh training method group is 120.5 kg/sec with an average difference in post-test 23 kg/sec. Furthermore, the average value of arm muscle strength in the complex training method group was 38.00 kg while the average value of hand muscle strength in the circuit bodyweight training method group was 32.10 kg with an average post-test difference of 5.9 kg. So it can be concluded that the basketball athlete group given the complex training method treatment has better leg muscle power and arm muscle strength compared to the circuit bodyweight training group.
