The purpose of this research study is to determine if muscle training will improve snoring and obstructive sleep apnea. Subjects will receive a sleep study to determine the severity of their apnea. After this study, subjects will be randomly assigned to one of two groups. The first group will receiving a breathing trainer that may strengthen the muscles used to breath in and out. The second group will be receive a sham trainer which looks like the "real" trainer but is not able to produce a strengthening effect. Both groups will complete eight weeks of home based (real or sham) training. The sleep study will be repeated and we well measure any changes in measures of severity for obstructive sleep apnea.
