In 1985, while teaching an aerobics class, she noticed her older adult clients suffering a high incidence of injury and attrition. In response, she designed a gentle program tailored to their needs. As students began reporting marked improvement in their physical and mental health, Wilson became convinced that there was a need for this type of exercise program on a national level.
