... effect of the crocodile push-up exercise program on arm muscle strength, with an average post-test measurement result of 20.67, which was higher than the pre-test measurement result of 17.27, there was a significant effect. The crocodile push-up exercise program has a significant effect on arm muscle power, with an average post-test measurement of 135.19, which is higher than the pre-test measurement of 117.36. There is a significant effect of the T push-up exercise program. on arm muscle strength, with an average post-test measurement result of 18.60, looks higher than the results of the pre-test measurement of 16.87, there is a significant effect of the T pushup exercise program on arm muscle power, with the results the average post-test measurement is 130.59, it looks higher than the results of the pre-test measurement of 119.77, there is a difference in the effect of crocodile training push-ups and T-push-up exercises on arm muscle strength. With the calculation results show the value of Sig. 000 > = 0.05 in the ANOVA test, so that the crocodile pushup exercise had a better effect than the T push-up exercise and the control group on increasing arm muscle strength. Based on the analysis above, it can be concluded that there is an increase in arm muscle strength and arm muscle power for each group after being given exercise. Crocodile push-up exercise gave a better effect than T push-up exercise and the control group on arm muscle strength and arm muscle power.
