    摘要: A weightlifting apparatus and method for preventing injury to a weightlifter from a weightlifting bar including weights thereon in the event of physical collapse of the weightlifter. The apparatus includes a framework having a base, a brace, a first pair of vertical support members secured to the brace and to the base and having a first slot therebetween with a structure defining a plurality of first apertures; and a second pair of vertical support members secured to the brace and to the base and having a second slot therebetween with a structure defining a plurality of second apertures. An adjustment body with adjustment apertures is slidably and adjustably mounted within the first slot and another adjustment body within the second slot. A bolt is threadably secured to the adjustment body for finely adjusting the height of a resting weightlifting bar with respect to a weightlifter. The process comprises placing the adjustment body within the first slot and the second slot, and inserting a pin through the first apertures and the adjustment apertures to retain one of the adjustment bodies within the first slot, and inserting another pin through the second apertures and the adjustment apertures of another adjustment body to retain the other adjustment body in the second slot.
