Kiiking (Estonian pronunciation: [ˈkiːkiŋ]) is a sport which involves a person making a swing gain increasingly more momentum, to pass over the spindle with the longest shafts possible. It was invented in Estonia by Ado Kosk in 1993;[1] in Estonian, kiik means a swing.
In a kiiking swing, the swing arms are made of steel to enable a person to swing 360 degrees going over the fulcrum of the swing. A person is fastened to the swing base by their feet. To swing, the person begins to pump by squatting and standing up on the swing. The swing will gain momentum and will, by skillful pumping, take a person over the fulcrum.
Kiiking is regulated by the Estonian Kiiking Association.
