Abstract
A weightlifting apparatus has multiple disc weights. Each disc weight has a round base and a round cover assembled on the round base. The round base has multiple locating slots formed therein. The round cover has multiple locating holes formed therethrough. When the locating slots align with the locating holes, lightweight weight plates or coins can be inserted into corresponding locating slots. When the locating slots misalign with the locating holes, the inserted weight plates or coins can be retained in the locating slots. Accordingly, easy weight adjustment and cost-saving effect can be achieved without requiring users to purchase an entire set of disc weights. With incremental fine weight adjustment of weight plates and coins, users can quickly adapt to the adjusted weight, and the exercise injury caused by large increment of weight adjustment can be avoided.
