Pentaque is one of the new sports that is quite popular in Indonesia with dominant games using arm and hand strength to throw small balls made of iron, in other words, “bosi”. This study aims to test the methods of these three exercises, namely biceps, Zottman curl, and dumbbell clean to improve the ability of the arm muscles in throwing or shooting accuracy for pentaque athletes. This type of research is a 3 × 2 factorial design experiment, including independent, dependent, and attributive variables with the research sample being the entire population, namely students of the Physical Education, Health and Recreation Study Program, Mulawarman University, totaling 36 students. Exercises to improve the results of shooting pétanque are carried out in 18 meetings which are carried out 3 times a week, the dose of exercise given is by doing exercises according to the group, namely biceps curls, dumbbell clean, and Zottman curls carried out in 3 sets and 8 repetitions with 1 minute of rest allowed between each interval, data analysis using one-way ANOVA. The results obtained in this study were the training methods and muscle strength obtained a significance value of 0.002 < 0.05, thus there was a significant interaction between the training methods (biceps curl, dumbbell clean, and Zottman curl) and arm muscle strength (high and low) on Improved petanque shooting accuracy.
