Elementary secretary Jeannie Lyonnais took her turn with a T-ball bat during last week's Gap Training workshop for Dayton School District staff and administrators. Only 600 lbs. of pressure are required to cause physical harm to the thoracic region of the body. None of workshop attendees applied less than 1,500 lbs. of pressure from the swing of their bats, according to Trainer Jon Ladines.
