Recess for children is typically enjoyed outdoors and has been defined as a break period from the relatively inactive routine of the classroom. Traditionally, recess has been loosely structured and has allowed children to freely choose their activities and playmates on the school playground. Recesses usually last 10 to 20 minutes, and most children choose vigorous activities, whether playing tag, climbing on playground equipment, or playing games with balls, jump ropes, and other equipment.1

Climbing walls are seen as a good way for children to begin climbing, because they offer a safe environment for learning the techniques of rock climbing before they attempt the challenges of mountain and rock climbing outdoors with their families.1
