Abstract: The invention relates to a structure for practicing the acrobatic and ludic form of sport consisting in creating figures in the air while being hung from elastic means (E) and, eventually, while bouncing on a flexible and/or elastic surface (T), the structure being formed by assembling elements (3, 4, 5) that create several exercising areas comprising, each, a pair of hanging-up points (41) at which the elastic means (E) are hooked in. It includes a base (1) which aggregates (2) of elements (3, 4, 5) are made integral with, independently from each other, each of the aggregates (2) having a globally triangular shape and being made integral with the base (1) through one of its angles and resting on the floor through another angle, while the third angle (41) forms one of said hanging-up points.
