The invention relates to a variable-weight pingpong bat. A bat body comprises three layers of fixed-weight clamp plates inlaid with permanent magnets and a variable-weight magnetic conductive counter-weight plate; hollow handle sleeves capable of being inlaid with counter-weight magnets are clamped at both sides of a handle of the bat body; according to the variable-weight pingpong bat disclosed by the invention, the traditional pingpong bat with standard-weight can be gradually increased in weight and balanced in the gravity center of the bat body by matching with the traditional standard rubber-faced structural materials, and gradual weight increasing training and standard weight competition can be realized. The variable-weight pingpong bat disclosed by the invention can be standardly, universally and industrially produced and widely used for the pingpong training and the wrist joint exercising.
