A novel exercise is described for resistance training of the lower esophageal sphincter. Resistance is provided by gravity as food is swallowed and pushed up an incline into the stomach. The incline is established by kneeling with the head bowed lower than the stomach. After several months of daily repetitions, symptoms of gastroesophageal reflux ceased and the exercise was discontinued without relapse.
