This creation system discloses a kind of sit-ups measuring device and its system. Wherein sit-ups measuring device includes measurement pedestal, the first sensor, the second sensor, processing mould group and counter. It measures pedestal and carries out sit-ups in its top for user's what, and two legs of what user are respectively set in the first sensor and the second sensor, and sensing presses power the first signal of generation and the second signal respectively. Handle the first sensor of mould group electrical connection and the second sensor and counter. When processing mould group receives one counting signal of the first signal and the generation of the second signal system, with the complete number of counter records user. This creation thereby, can have standard and certainly measure the sit-ups number of user.本創作係揭示一種仰臥起坐測量裝置及其系統。其中仰臥起坐測量裝置包含測量基座、第一感測器、第二感測器、處理模組及計數器。測量基座供使用者於其上方進行仰臥起坐，而第一感測器及第二感測器分別設置於使用者的兩個腿部，且分別感測壓按力產生第一訊號及第二訊號。處理模組電性連結第一感測器及第二感測器及計數器。當處理模組接收到第一訊號及第二訊號係產生一計數訊號，以計數器記錄使用者完的次數。本創作藉此，可有標準且確實地測量使用者的仰臥起坐次數。
