Abstract: A swinging and hitting training device for use by athletic participants of golf, baseball and the like includes a mouth receiving member or a chin strap for temporarily fixed engagement with the head of the user. A force transmission element, such as a strap, extends from the head engaging device and is provided with at least one and preferably two strap connections. From the strap connections extend a pair of angularly related adjustable elastic straps having clips at their free extremities for releasable connection to the clothing of the user, particularly at the belt line. During swinging activities for hitting golf balls, baseballs and the like, undesired head movement will impart a force to the resilient straps which force is resisted. The resistance force is capable of being felt by the user, thus enabling self-determination by the user that improper head movement has occurred during swinging.
