The purpose of this research study was to study the effect of Circuit and Plyometric training on the flexibility of students. In this research study, students of M. M. Ghodasara Mahila Arts and Commerce College, Junagadh, aged 18 to 25 years, were randomly selected and stratified into 3 groups. In this research study, they were divided into three groups: Group-A Circuit (30), Group-B Plyometric (30) and Group-C Control (30). A total of 90 subjects were randomly selected in this research study. The standard of measurement for flexibility was the Sit and Reach Test. In this research study, subjects were randomly selected. 30 subjects were placed in each group. A pre-test of speed was conducted on each group. Then group-A was given Circuit training and group-B was given Plyometric training for 08 weeks and group-C was kept as the control group. After that, the post-test of all three groups was taken. To know the effects of Circuit and Plyometric training on the group, one-way analysis of covariance test was applied and the differences between the means were tested for significance at the 0.05 level by Least Significant Difference Post Hoc test. The conclusion was as follows. A significant improvement was observed in the flexibility of the subjects selected from the 08-week Circuit training and Plyometric training program of the method.
