Afterschool programs often play an important role in promoting healthy lifestyles for youth. Many programs offer youth opportunities to engage in an array of organized physical activities such as softball, martial arts or ballet. Most programs also serve healthy afternoon snacks while emphasizing the value of a nutritious diet. Physical fitness activities after school not only promote health but also serve as crime deterrents, teach youth positive values, and impart knowledge and skills to help youth establish lifelong healthy habits.
