Slacklining is a balance sport that involves walking or balancing along a flat, narrow piece of webbing tensioned between two anchor points. The webbing is typically made of nylon or polyester and can be set up at various heights, from a few inches off the ground to several feet high. Slacklining can be practiced in various environments, including parks, backyards, and even urban areas. Participants use their core strength and focus to maintain balance while walking, jumping, or performing tricks on the line. It is a popular activity for both recreational and competitive purposes, often fostering a sense of community among enthusiasts.
