The data were analyzed by Mann Whitney test.The results showed that in the group given postpartum exercise intervention 14.50&gt; the group that was given postpartum exercise intervention and relaxation techniques. It means that the subinvolution score was greater. Mann Whitney test ρ&lt;0.05, it indicates that the mean rank difference between the two groups was significant. In short, postpartum exercise and relaxation technique were effective in accelerating the process of uterine involution.Last, it is suggested to the midwives to improve and perform midwifery services by applying postpartum exercise methods and relaxation techniques to make the uterine involution process runs well.</em></strong></p><p><strong><em> </em></strong></p><p><strong><em>Keywords : The Effectiveness, Postpartum Exercise, Relaxation Techniques</em></strong></p><p><strong><em>References : 26 (2004-2019)</em></strong></p>
