Abstract
Recommendations for regular exercise have been evident in the nursing literature since the early 1900s. Health professionals and popular media have promoted vigorous exercise for positive health benefits since the 1960s. The concept of exercise as it appeared in the nursing literature during the early part of the 20th century is closer to the concept of physical activity of today-regular, moderate-intensity activities that become part of one's lifestyle. Nurses are in a unique position to counsel individuals, families, and communities on the importance of regular physical activity and to correct misconceptions that only vigorous exercise has health benefits.
