How can i do kegel exercise correctly and how often do i need to do it?
A Kegel exercise, named after Dr. Arnold Kegel, is an exercise designed to strengthen the pubococcygeus muscles. The exercises consist of the regular clenching and unclenching of the muscles which form part of the pelvic floor (sometimes called the "Kegel muscles").
From another site:
go to the bathroom and sit on the toilet (men, it is also a good idea to sit for this).
in the middle of your stream of urine, stop and start the stream several times. The muscles you use to do this are your PC muscles. At first, you may find that you are also squeezing your anal muscles; as you become experienced with kegel exercises, try to separate out the muscle groups that you are able to exercise by squeezing.
