This creation system discloses a kind of pushup measuring instrument comprising measuring instrument pedestal, the first sensor, the second sensor, processing mould group and counter. Wherein, it on the first sensor setting what measuring instrument pedestal, when user pushes, senses the movement of user and generates the first signal； The setting of second sensor has predetermined altitude on the bracket of the connection what measuring instrument pedestal, and the second sensor senses the movement that user stands up and generates the second signal. Processing Mo Zu connects the first sensor and the second sensor respectively, receives the first signal and the second signal, and be connected to counter, the number that record user completes, wherein receives the first signal and the second signal is considered as the movement for completing a pushup.本創作係揭露一種伏地挺身測量儀，其包括測量儀底座、第一感測器、第二感測器、處理模組以及計數器。其中，第一感測器設置於測量儀底座上，在使用者下壓時，感測使用者之動作而產生第一訊號；第二感測器設置在連接於該測量儀底座之支架上，並具有預定高度，第二感測器感測使用者起身之動作而產生第二訊號。處理模組分別連接第一感測器及第二感測器，接收第一訊號及第二訊號，並連接至計數器，記錄使用者完成的次數，其中，接收第一訊號與第二訊號視為完成一次伏地挺身之動作。
