Through the setting of the waist protection device 5, the lumbar support 58 can continuously support and protect the waist of the parturient during yoga exercises, and the height of the lumbar support 58 can be adjusted according to the requirements of the parturient. Since the pressure on the waist of the parturient is relatively large, supporting and protecting the waist during yoga exercises can relieve the pressure on the waist, and help maintain the balance of the body, so as to avoid waist injuries of the parturient during yoga exercises.

[0032] When the parturient performs yoga in a sitting or lying position, the sweat on her body will drip onto the inner plate 32 and the two outer plates 33. When the two sliders 44 move upward, the two sliders 44 pull the two drawstrings 61 respectively. When the two drawstrings 61 are pulled, they will respectively drive the two connecting rods 63 to move in the direction close to the sliders 44. The two connecting rods 63 drive the mounting plate 64 to move in the direction close to the front armrest 43. The mounting plate 64 drives the sponge 65 to move in the direction close to the front armrest 43. When the two outer plates 33 are separated, the sliders 44 are used to pull the two pullstrings 61. 4 and the torque of the torsion spring tube 62, so that the two pull ropes 61 drive the mounting plate 64 and the sponge 65 to reset, and the sponge 65 wipes the sweat on the two outer plates 33 and the inner plate 32 during the movement. By setting the sweat removal device 6, the sponge 65 can wipe the surface of the two outer plates 33 and the inner plate 32 every time the parturient manually separates or closes the two outer plates 33, thereby preventing the parturient from slipping due to stepping on the residual sweat when stepping on the outer plates 33 and the inner plates 32, thereby further improving safety.
