Despite the clear benefits of physical activity for women, few women obtain the recommended levels of physical activity. To address adherence to physical activity in this group, it is important to understand the barriers to physical activity that affect women. These barriers may include lack of time; anticipated lack of enjoyment; self-consciousness about body size, shape, and physical activity ability; and urinary incontinence. By addressing barriers to physical activity, health care providers may experience greater success in their efforts to increase physical activity in their female patients.
