Slackline

Slacklining involves walking, jumping, and performing tricks on a flat webbing stretched between two anchor points, usually trees or posts. Originating in the 1980s among mountaineers as a balance training method, the discipline has diversified into static and dynamic variations (walking, tricklining, longlining, highlining). The principle relies on the ability to maintain balance on an elastic webbing that oscillates and returns the energy of the movements.

The technique combines posture, weight centering, micro-adjustments of the ankles and hips, and breath control. Basic equipment includes a wide webbing (25–50 mm), an anchoring and tensioning system (carabiners, pulleys, or jack/ratchet), anchor protection, and, for highlining, a leash and safety devices. The level of difficulty ranges from balance exercises accessible to beginners to long, aerial lines requiring training, physical preparation, and technical precision for safe progression.
