In this embodiment, the control device 330 may receive the code of the selected weight 104 from the weight detection pin 200 through the second communication module 310, for example, “01100”. The memory 320 can store a look-up table LUT, where the look-up table LUT pre-records the code and the corresponding training weight value. For example, the code "00001" means the training weight is 2 kg, the code "00010" means the training weight is 4 kg, the code "01100" means the training weight is 48 kg, and so on, but not limited.

In another embodiment, the look-up table LUT may be stored in the weight detection pin 200, and the weight detection pin 200 directly transmits the value of the training weight as the weight information to the computing device 300.
