Referring to Figures 4 and 5 with respect to the use state of the present invention configured as described above are as follows.

First, reference is made to FIG. 4 is a plan view showing a rotation operation state of the seat plate 10, which is a bearing formed in the lower part when the user rotates artificially left and right in a state where the user is slightly spaced apart from the backrest 40 while sitting on the seat plate 20. The member 223 is rotated about the support shaft 221 formed in the fixed frame 10 so that movement of the waist is possible, and the seat plate 20 is a handle combined armrest fixed to the fixed frame 10 ( Separately from the back 30 and the back 40 is to be rotated about the fixed frame 10, so that an effective smooth back movement is possible.

Next, an abdominal exercise will be described with reference to FIGS. 5A, 5B, and 5C.

First, in order to perform an abdominal exercise, the backrest 40 with respect to the seat plate 20 is adjusted using the support bar 45 and the adjusting pin 46 as shown in FIG. 30) with both hands, the footrest 64 is in close contact with the backrest 40 while the foot is in the state, and then slowly back the backrest 40 as shown in Figure 5b, the backrest 40 is a backrest support 42 ), The backrest 40 has a rear end at the center of the adjustment pin 46 of the support bar 45 which is connected and supported between the fixed rear crust 50 and FIG. Likewise, it is completely reread back. At this time, the degree of recline of the backrest 40 may vary under the intention of the user, and the head of the user is stably supported by the head restraint 41 whose length can be adjusted.

When the rear end of the backrest 40 is flipped in a state as shown in FIG. 5C with respect to the adjustment pin 46, the backrest 40 is mounted on the fixed frame 10 as opposed to the operation of the backrest 40 that is flipped backward. The rear end of the seat plate 20 is lifted upward. That is, at the same time the rear end of the backrest 40 is turned around the support bar 45 and at the same time, the connecting piece 12 supported by the first hinge 43 at one end of the backrest support 42 is the adjustment pin 46. As the fixed frame 10 provided with the first hinge 43 is pulled by the center, the rear end of the seat plate 20 mounted on the fixed frame 10 is simultaneously inclined upwardly. At this time, the seat plate 20, which is lifted upward at the same time as the fixed frame 10, is adjusted to the support angle adjusting hole 44 formed of the backrest base 42 around the first hinge 43 of the connecting piece 12. The farther the distance between the axes of the pins 46 is adjusted, the greater the angle that is inclinedly lifted upward.

In addition, the opening angle control pin 70 installed as the fixed frame 10 in response to the rear end of the seat plate 20 being inclined to be lifted upwardly is movable front perception that is penetrated and supported by the fixed frame 10 so as to be in contact therewith.
