A weight-lifting apparatus includes a plurality of weights each having a central hole and a slot extending from the central hole to a perimeter of the associated weight, the slot having a width less than the diameter of the central hole. The apparatus further includes a shaft having opposing ends defining a diameter about equal to the central holes, and a sleeve positioned on the shaft. The shaft is shaped to rotatably engage the central holes and is rotatable to different positions. The shaft further has a plurality of recessed surfaces on the opposing ends corresponding to the different positions that extend different longitudinal lengths, the recessed surfaces defining with other surfaces on the shaft a reduced dimension about equal to the width of the slot. Further, the shaft and the weights are configured so that by rotating the shaft, the recessed surfaces are selectively positioned to allow the shaft to slide along one or more of the slots, thus selectively releasing the weights. A method related to the above apparatus includes providing a weight-lifting apparatus having a plurality of weights and a shaft shaped to selectively engage one or more of the weights, rotating the shaft to selectively engage a desired number of the weights, and lifting the weight-lifting apparatus with the selected weights held on the shaft. A person using the weight-lifting apparatus can easily rotate the shaft to select a desired number of weights without interrupting their exercise routine.
