A nasal dilator is provided that can be used primarily for exercise and secondarily rest/sleep. It may be designed as a resilient bridge between two arms that enter the nostril then expand the nostril outward and upward. In one embodiment the dilator is flexible and the feet are brought together when inserted and when released they return outward and press against the nasal wall thus opening the nostrils. The feet may have an offset from the arm to deeper engage the nostril which helps to prevent the dilator from slipping off. Also the inside face of the feet and arm that run parallel to the septum wall may be generally flat to prevent irritation to the septum wall if pressed up against the septum wall. The easy to use and reusable nasal dilator can be used by athletes to better performance through improved utilization and flow of air.
