The purpose of Kegel exercises are to improve the muscle tone by strengthening the PC muscles of the pelvic floor. 
It is a popular exercise for pregnant women to prepare the pelvic floor for vaginal childbirth. 
Kegel exercises also help in regaining pelvic floor muscle strength due to pregnancy, childbirth, age and being overweight. 
Also as you get older the muscles naturally relax and you may find that coughing, laughing etc cause slight stress incontinence.
Regular pelvic floor exercise can help reduce this sometimes embarrassing condition after only a few weeks use.
