Abstract: A weight lifting system including a handle or bar that is adapted to be connected to a weight plate. The weight plate includes a central opening that extends through the weight plate. One end portion of the handle is inserted into one end of the opening within the weight plate. A bolt is extended into the opening of the weight plate, from the opposite side, and threaded into a threaded bore formed axially within the end portion. A shoulder is formed intermediately within the opening of the weight plate. As the bolt is turned and threaded into the threaded bore, the end portion of the handle is drawn towards the shoulder while a head portion of the bolt moves towards the shoulder. By securely tightening the bolt within the threaded bore, the bolt head is brought into contact with the shoulder and thereby the inward movement of the bolt is limited.

Abstract: A body building or therapy adjustable weight exercise device for use in strengthening hands, arms, chests and neck of a person using the same, wherein it is either a barbell or dumbbell including a central bar section to be gripped by a hand or hands with equal poundage weights at each end of the bar, and weights holding-locking means to affix the weights to the central bar and auxiliary disk weights capable of being removably mounted on the holding-locking means to alter the total weight of the device.
