I didn't know such a thing existed! I would love to know how to do these and wonder if a gastroenterologist could tell me. The article does not go into much detail about how these or done.
I'd like to know who can advise me on doing these exercises, how often to do them and the results I might be able to expect from them. The idea of doing exercises and perhaps being able to cut down on my heartburn medication is an attractive one.
I guess, since nearly everything else can be exercised, this sphincter muscle can be also.
