A gymnastic apparatus having horizontal laminated bars substantially of wood, wherein each bar comprises upper and a lower lamena glued together at an interface therebetween, and wherein longitudinal, cord-like inserts of elastic, synthetic material of inorganic origin are disposed in grooves of the lamenas. The bar is symmetrical along an imaginary vertical center line. The lamenas have at least three inserts. The direction of the fiber of the upper of the lamenas extends substantially vertically. Two of the inserts are disposed in the upper lamena and engage the interface provided between the upper and lower lamenas, and the third of the inserts is disposed in the lower lamena and extends to the lower outer face of the lower lamena.
