Slacklining is balancing and doing tricks along a suspended length of flat webbing that is tensioned between two anchors, most often trees. Slacklining was invented in the early 1980s by two Yosemite rock climbers, Adam Grosowsky and Jeff Ellington. The webbing is from 1 to 2 inches (2.5-5cm) wide and made of nylon/polyester. It is similar to tightrope walking, though differs in the material used and the amount of tension applied (less tension on slacklines).

Slacklining is both a sport and art. As a sport, there is a Slackline World Cup and other major competitions. One of the most popular forms of slacklining that is practiced is tricklining, in which tricks such as running, jumping, sitting, knee drops, 180s/360s, flips, butt and chest bounces.
