Abstract: The application relates to a dumbbell which is convenient for adjusting a load. By arranging telescopic sleeves which can be telescopically adjusted in a handle of the dumbbell, a number of counterweights nested on the telescopic sleeves is controlled, thus achieving an easy adjustment of the load. By arranging a rotatable knob, the telescopic sleeves inside the handle are driven to act through a gear transmission. Meanwhile, due to a position limitation of a division bar of the dumbbell, the counterweights nested on the telescopic sleeves are prevented from sliding left and right, thus ensuring a firm coupling.
