I know a bunch of people who have overcome theirincontinence with it.

Need to go to someone who has experience and additional education in this area. It is definately a speciality.

A kegel is the name of a pelvic floor exercise, named after Dr. Kegel who discovered the exercise. These muscles are attached to the pelvic bone and act like a hammock, holding in your pelvic organs. To try and isolate these muscles trying stopping and starting the flow of urine.

Why would I want to do kegel exercises?

Kegeling provides many benefits:
Conditioned muscles will make birth easier, and your perineum will more likely be intact (fewer tears and episiotomies)
Sexual enjoyment is enhanced for both partners
It can prevent prolapses of pelvic organs
It can help prevent leaking urine when you sneeze or cough
How do I do the kegel exercise?

Once you have located the muscles simply tighten and relax the mucsle over and over, about 200 times a day. These are basic kegels. There are many variations on kegels: elevator kegels (Where you tighten slowly, in increments going in and out, like an elevator stopping on several floors.), you can hold the muscle tightened for five seconds, you can bulge the muscles out at the end, and many other variations.

Kegel exercises are designed to strengthen your pelvic floor muscles (also called your PC muscles ). Kegel exercises can be good for women who are experiencing incontinence (as a result of childbirth, medical treatment, or changes/stress on the body), and they have also been recommended as a way of changing how orgasms feel (some, but not all, women say it enhances their orgasms).

The basic exercise can be done anytime and anywhere. Just squeeze your PC muscles as hard as you can, and hold them. This is doing a kegel exercise. Start by squeezing and holding for a count of 3-5 seconds, then release and relax for 5 seconds. When you release, notice how your muscles feel. The first time you do a kegel exercise see how many times you can do it before you feel your muscles getting tired.

kegel exercises will be most efficient and have the most impact if you get into doing sets of repetitions of the squeezing. Once you’ve found your baseline, you can work from there. If you can, start with doing 5 repetitions (squeeze/hold/release). Judge for yourself how long you can hold the squeeze for, but don’t push yourself too much at first.

Once you’ve found your baseline, do your exercises, and every couple of days increase both the length of time you hold the squeeze for, and the number of exercises per set. As a guideline, try to work up to a point where you can hold the squeeze for ten seconds. And try to work up to doing ten reps of kegel exercises per set. So you squeeze, hold for ten second, release, relax for ten seconds, and repeat ten times.people will use a toy or kegel exercising device to add resistance to kegel exercises. This is not necessary, and while some sex educators suggest it increases the usefulness of the exercise, doing them on your own is still a great way to develop your PC muscle. If you are interested in purchasing a product for kegel exercises, make sure it isn’t too large

Tips:
Isolate the PC muscle when doing your kegel exercises. At the beginning, remember to regularly check that you are exercising your PC muscle, and not other muscles. Avoid contracting your abdominal, thigh, or buttocks muscles. This is something many people do, but it reduces the effectiveness of the kegel exercise Concentrate on breathing and trying to keep yourself relaxed, and only tense the PC muscles you are using. Try not to tense up your whole body.

Finding time to do your kegel exercises. You don’t need to set aside a big chunk of time to do kegel exercises. Do a few reps while waiting for a stop light to turn green. In the last ten minutes before lunch, when you’re sitting at a desk, do a few reps. Do them while you’re waiting for the movie to start, or a commercial break to be over.

Don’t overdo your kegel exercises.Like any exercise, it’s important to build up slowly, and pay attention to your body. If you are experiencing pain or discomfort, you are pushing yourself too hard. It is possible that you could strain the muscles and aggravate a current problem, when you are trying to resolve it.

Kegel exercise products can be fun and helpful but they aren’t necessary.There are more and more products, often called “kegelcisors” on the market. While some of these can genuinely increase the strengthening exercises, and some of them double as fun sex toys, remember that they are not necessary. You don’t need any special work out clothes or paraphernalia to do kegel exercises properly
