A hurdle obstacle utilized curved bars of selected sizes each supported in the apex of a standard module conical base such that a main portion of the bar extends parallel to the ground for jumping over or moving beneath. One end of the obstacle bar is swivelably engaged in the base by means of a flanged bushing which receives one end of the bar so that upon impact with a user, the safety obstacle device swivels out of the user's path to prevent tripping or other injury.
