A batting training aid and method of use to improve baseball players' batting stance and swinging motion. The stance is characterized by a high center of gravity, erect posture with one leg forward, and the other backward. The proper swinging motion is around a vertical axis. The batting training aid comprises: a waist belt; an anklet; a stirrup attached to the anklet; a strap connected at one end to the belt and at the other to the anklet. The length of the strap is adjusted to a predetermined length set to the maximum separation between the back ankle and the waist and configured to force players into the proper batting stance and proper swinging motion. The method of use comprises adjusting the length of strap; adopting batting stance; batting at ball; sensing a tug between the waist and the ankle; and correcting the batting stance to eliminate the tug.
