PURPOSE: A device for sensing the weight of a weight block is provided to display the movement number and the momentum of weight blocks on a display unit or transmit the movement number and the momentum to a sever. CONSTITUTION: A device for sensing the weight of a weight block comprises a magnet(21), a magnet switch(23), and an electric circuit. The magnets are installed on one side of the weight blocks, respectively. The magnet switches operate when the magnet is moved. The electric circuit senses the number of the weight block numbers which is vertically moved by sensing signals. The sensing signal is generated when a specific magnet switch operates among magnet switches.
