The fourth hinge shaft 219 is fastened in the second fastening groove 233, thereby realizing the rotational connection of the back plate 23 and the seat plate 211, and the structure can conveniently detach the back plate 23, so as to reduce the space occupied by the exercise chair 21 in the folded state.

As shown in fig. 1, the exercise seat is located between a first vertical beam 111 and a second vertical beam 112, and lift arm assembly 22 is drivingly connected to barbell assembly 12 via first drive member 30. In this embodiment, the first transmission member 30 includes a first connecting rope 31 and a second connecting rope 32. One end of the first connecting rope 31 is connected with the barbell bar 121 of the barbell assembly 12, the other end of the first connecting rope 31 is connected with the first grab handle 2213 of the hand lifting frame 221, and the first connecting rope 31 bypasses the guide wheel 118 at the top of the supporting frame 11 and the guide wheel 118 on the underframe 213 of the body-building chair 21. After the hand lifting frame 221 is in transmission connection with the barbell assembly 12 through the first connecting rope 31, the barbell assembly 12 has a tendency of preventing the hand lifting frame 221 from rotating upwards, namely, during the upward rotation of the hand lifting frame 221, the barbell assembly 12 moves vertically upwards along the strip-shaped through hole 1111 under the traction action of the first connecting rope 31. One end of the second connecting rope 32 is connected with the barbell bar 121 of the barbell assembly 12, the other end of the second connecting rope 32 is connected with the second grab handle 2223 of the foot lifting frame, and the second connecting rope 32 bypasses the guide wheel 118 at the top of the supporting frame 11 and the guide wheel 118 on the underframe 213 of the body-building chair 21. After the foot lifting frame is in transmission connection with the barbell component 12 through the second connecting rope 32, the barbell component 12 has a trend of preventing the foot lifting frame from rotating upwards, namely, in the process of rotating the foot lifting frame upwards, under the traction action of the second connecting rope 32, the barbell component 12 moves vertically upwards along the strip-shaped through hole 1111.

In use, a user can sit on the seat 211 of the exercise chair 21, hold the first handle 2213 and drive the hand lifting frame 221 to rotate upwards, thereby achieving the purpose of exercising the hands. The user can adjust the backup plate 23 to the upward inclined position through the supporting piece 24, and the user can sit on the seat 211 and lean on the backup plate 23, and the feet lean on the second I handle and drive the foot lifting frame to rotate upwards, so that the aim of exercising the legs is achieved.
