Slacklining is a balance sport that involves walking or balancing on a flat webbing tensioned between two anchor points, such as trees or poles. The webbing is typically made of nylon or polyester and can vary in width and length. Slacklining can be practiced at different levels of difficulty, from simple walking to performing tricks and stunts. This activity is often enjoyed in parks, backyards, or natural settings, and it promotes core strength, focus, and coordination. Slacklining has gained popularity among outdoor enthusiasts and is sometimes used in training for other sports, such as rock climbing and parkour.
