  Introduction and purpose: The aim of the present study was to investigate the effect of eight weeks of resistance training with a double and flat pyramid pattern on the speed, endurance, agility and explosive power of non-training handball players in the Covid-19. Materials and methods: This research was semi-experimental with a pre-test-post-test design. The statistical population of the present study includes the handball players of Zanjan province who did not exercise for at least 6 months during the Corona era. The statistical sample of this study was randomly selected from among 36 athletes and they were divided into three groups of 12 people (double pyramid group, flat pyramid group and control group). The exercise program of the flat and double pyramid groups was carried out for eight weeks (three sessions per week), respectively, with a training intensity of 60% and 80% of one maximum repetition. Shapiro-Wilk statistical test was used for the normality of data distribution. Correlated t-test and ANOVA were used to compare intra-group and inter-group averages. Results: The results showed that the endurance records of 5000 meters and 4 x 9 meters of untrained handball players decreased by 13.21% and 16.48%, respectively (P/>05). In addition, the explosive power of the subjects during the Sargent jump (in cm) from the pre-test to the post-test stage increased by 15.34% (P=0.021).Discussion and Conclusion: It seems that strength training with a double pyramid pattern has been effective in improving the agility, explosive power of lower limbs and endurance of untrained athletes.
