To test for normality using the Lilifours test at a significant level of 0.05α. Based on the analysis of the normality test of the X data, the Lcount is 0.1348 and Ltable is 0.167, meaning that Lcount <Ltable. while the Y variable produces a Lcount of 0.1452 and an Ltable of 0.167. This means Lhitung <Ltable. then the data is normally distributed. Thus it can be concluded that for the effect between variable x and variable y, the value of t = 6.45 is obtained, then tcount> ttable, namely (6.45)> (1.703), then Ha is accepted, in other words there is a significant effect on the effect of standing exercise.
