ABSTRACT:
A waist building device comprises a frame, two urging members, a shaft, a flexible piece, a linking mechanism, two pull rods, and two connection rods. The urging members are mounted respectively at both ends of the upper side of the frame. The shaft is slidably received in a shaft hole of the frame. The flexible piece is fastened with the shaft such that both ends of the flexible piece are urged respectively by the urging members. The linking mechanism is located at the bottom of the frame such that the linking mechanism is interchangeable between a horizontal motion and a vertical motion, and that the linking mechanism is connected with the shaft. Two pull rods are fastened pivotally at the bottom ends thereof with both ends of the bottom of the frame. Two connection rods are fastened with the pull rods and the linking mechanism for causing two pull rods to actuate the linking mechanism which in turn actuates the shaft to slide up and down.
