Kegel exercises are easy to do and can be done anywhere without anyone knowing.
First, as you are sitting or lying down, try to contract the muscles you would use to stop urinating. You should feel your pelvic muscles squeezing your urethra and anus. If your stomach or buttocks muscles tighten, you are not exercising the right muscles.
Once you've found the right way to contract the pelvic muscles, squeeze for 3 seconds and then relax for 3 seconds.
Repeat this exercise 10 to 15 times per session. Try to do this at least 3 times a day. Kegel exercises are only effective when done regularly. The more you exercise, the more likely it is that the exercises will help.
These were the only proper directions I could find. Once you get the hang of them they are easy. Basically, the same muscles that you pushed with during delivery, are what you are contracting. My doctor told me that if I was having trouble to practice while going to the bathroom. Try urinating for three seconds then stopping and holding for three seconds.
They can come in handy in your love life too.
