And the user sets the exercise time for sit-ups using the minute setting button 44 or the second setting button 46, every time the minute setting button 44 is pressed and set by one minute, the second setting button ( Each press of 46) increments by 1 second. At this time, in step 211, the CPU 60 checks whether the minute setting button 44 is turned on and proceeds to step 212 when the minute setting button 44 is turned on. In step 212, the CPU 60 increases the minute by one every time the minute setting button 44 is turned on and displays the minute display part 38 on the display part 34. In addition, in step 213, the CPU 60 checks whether the second setting button 44 is turned on. If the second setting button 44 is turned on, the CPU 60 proceeds to step 212. In step 212, the CPU 60 increases the minute by one every time the minute setting button 44 is turned on and displays the minute display part 38 on the display part 34.

After setting the exercise time as described above, the start / stop button 42 installed in the display unit 34 is checked in step 215, and if the start / stop button 42 is turned on, the process proceeds to step 216. In step 216, the CPU 60 checks whether the exercise time is set and proceeds to step 211 to set the exercise time if the exercise time is not set. However, if the exercise time is set, the process proceeds to step 217 and the CPU 60 operates the timer 62 to count down from the set time and displays the down counting state on the minute display unit 38 and the second display unit 40. .

The person who wants to exercise in the state where the exercise time is down counting starts the sit-up exercise, and the back part of the person who is exercising is switched on by contacting the first sensing switch 14 installed on the back mat 12. And, as the body of the exerciser ascends upwards, the light emitted from the light emitting sensor 22a of the optical sensor 20 installed on both sides of the pair of support rods 18 is blocked, the light receiving sensor 22b The CPU 60 detects this and recognizes that the sit-up exercise has been completed once, and then counts up the number of exercises by one according to the repetition thereof. That is, in step 218, the CPU 60 checks whether the first detection switch 14 is turned on, and when the first detection switch 14 is turned on, the CPU 60 proceeds to step 219. In step 219, the CPU 60 checks whether light emitted from the light emitting sensor 22a of the light sensor 20 is blocked by the light receiving sensor 22b, and when it is detected that light is blocked by the light receiving sensor 22b, step 220. Proceed to In step 220, the CPU 60 checks whether the knee contact sensor 54 is turned on. In this case, when the knee contact sensor 54 is turned on, the CPU 60 recognizes that the elbow is in contact with the elbow of the person who exercises, and in step 221, the CPU 60 counts the number of sit-ups by 1 and counts the counted exercise count as the exercise count display unit ( In 36). After that, in step 222, the start / stop button 42 provided on the display unit 34 is checked to be on, and when the start / stop button 42 is turned on, the controller recognizes as a command to stop the counting of the number of times and the set time and proceeds to step 223. Proceed. In step 223, the CPU 60 stops the counting and time counting operation and proceeds to step 224. In step 223, if the reset button 41 provided in the display unit 34 is turned on, if the reset button 41 is turned on, the process proceeds to step 225. In step 225, the CPU 60 initializes the number of workouts and the set time to zero and terminates the program. However, if the start / stop button 42 is not turned on in step 222, the process proceeds to step 226 to check whether the set time has elapsed. If the set time has not elapsed, the process returns to step 218 and the cumulative counting of the sit-up exercise count is continued. Display on the exercise count display unit 36, and the program ends when the exercise setting time ends.

In the embodiment of the present invention, the ankle fixing unit 28 is operated by a switch to be electrically operated, but the ankle fixing unit 28 may be implemented in a stationary manner in which the ankle fixing unit 28 is not moved.

As described above, the present invention automatically displays the number of workouts for a set time when doing sit-ups, so when the fitness tester checks the time using a clock, it does not check the number of workouts to solve the inconvenience. At the same time, a fair evaluation can be made by an objective evaluation rather than a subjective evaluation, and one evaluator can evaluate several people at the same time.
