The gymnastic apparatus has a prefabricated base module (1) fixed to a wall, with two identical vertical bars (11) joined by cross bars (12). The vertical bars have holes (14) which hold between 6 and 15 removable horizontal bars (13). A safety mattress (10) is placed in front of the apparatus. Supplementary modules can be fixed to the base module. A bracket can be fixed to the upper cross bar to hold suspended rings, a rope, a punch bag or a rope ladder. A swing can be attached to a lower bracket.
