S103, when the motion trail of the dumbbell is judged to be inconsistent with the corresponding standard motion trail in the preset database, first voice prompt information is generated.

After the motion trail curve of the dumbbell is determined, a plurality of standard motion trails are stored in the database in advance. And comparing the current motion track of the dumbbell according to the calculated current motion track of the dumbbell, if the current motion track is inconsistent with the standard motion track, indicating that the user deviates from the standard motion curve, and generating first voice prompt information by a voice prompt built in the dumbbell to prompt the user to train according to the standard motion track.

It should be added that, when the single chip microcomputer in the dumbbell determines that the movement locus has a deviation, the direction and the displacement of the deviation are calculated correspondingly. And the user is prompted to correct the correct motion track direction through voice prompt, so that the exercise quality is improved.
