When the student need carry out the sit up training, at first the student sits on cushion 3, then both feet step on in shank supporting mechanism 5, make shank supporting mechanism 5 operation again, until the shank is crooked to comfortable angle, the student leans on the back in supplementary mechanism 4 of standing up again, ten fingers are alternately held behind the brain afterwards, and begin to carry out the sit up motion, then can make supplementary mechanism 4 operation of standing up, supplementary mechanism 4 of standing up can assist the student to get up the body simultaneously, the purpose of supplementary training has so been reached, treat that the student accomplishes the training after, the student leaves cushion 3 and supplementary mechanism 4 of standing up, and make the shank leave shank supporting mechanism 5, shank supporting mechanism 5 and supplementary mechanism 4 of standing up stop running and resume the normal position this equipment this moment, if reuse above-mentioned step can.

The student sits on the cushion 3, leans against the connecting plate 41 at the back, meanwhile, rests the head on the headrest 42, then moves on the back, so that the connecting plate 41 rotates downwards, meanwhile, the connecting plate 41 slides downwards on the first sliding rail 43, the first spring 44 is changed from the initial state into the compressed state, meanwhile, the connecting plate 41 drives the headrest 42 to move downwards, then, the student stops pressing the connecting plate 41, the first spring 44 is reset from the compressed state, the connecting plate 41 and the headrest 42 are moved back to the original position through elasticity, and then the student is assisted to get up, the purpose of assisting in getting up is achieved, the student repeats the steps, so that sit-up training is conducted, after the student finishes training, the student leaves the cushion 3 and the connecting plate 41, and the first spring 44 enables the connecting plate 41 and the headrest 42 to return to the original positions.

After a student sits on the seat cushion 3, the student steps on the pedals 52 with two feet, then the force is exerted by the two feet, the sliding block 51 slides to the right in the inner mounting plate 2, the pedals 52 further move to the right, the first connecting rod 53 slides to the right in the first support 54, the second spring 55 is changed into a compressed state from an initial state, the student stops moving the pedals 52 when the legs of the student bend to a comfortable angle, then sit-up training is started, after the student finishes the training, the student leaves the two feet from the pedals 52, and the second spring 55 is reset from the compressed state, so that the sliding block 51 and the pedals 52 move back to the original position.

When the sliding block 51 moves rightwards, the sliding block 51 drives the sliding sleeve 66 to move rightwards, the second connecting rod 65 slides downwards in the sliding sleeve 66, the second support 61 slides downwards in the second support 61, the pressing block 63 moves downwards, after the pressing block 63 is moved to be in contact with the legs of a student, the legs of the student can enable the pressing block 63 to slide upwards in the mounting frame 62, the third spring 64 is changed from an initial state to a stretching state, the pressing block 63 presses the legs of the student, the automatic leg pressing effect is achieved, the training effect can be prevented from being influenced by the fact that the legs of the student do not move randomly during training, after the student completes training, the sliding block 51 and the sliding sleeve 66 move back leftwards, the mounting frame 62 moves back to the original position, meanwhile, the legs of the student leave the pressing block 63, the third spring 64 resets from the stretching state, and the pressing block 63 returns to the original position.

When a student performs sit-up training, a worker can turn on the electric fan 72, manually enable the electric fan 72 to slide leftwards on the second sliding rail 71, the fourth spring 73 is changed from an initial state to a stretching state, then the worker loosens the electric fan 72, the fourth spring 73 is reset from the stretching state, the electric fan 72 is moved back to the original position, the worker enables the electric fan 72 to move leftwards and rightwards repeatedly, the electric fan 72 moves and blows air to the student who is training, the heat dissipation effect is achieved, the training time of the student can be prolonged, after the student completes the training, the worker does not move the electric fan 72 any more, and then turns off the electric fan 72, and the electric fan 72 stops blowing air.

When the connecting plate 41 rotates downwards, the connecting plate 41 drives the rack 81 to move downwards, the rack 81 moves to rotate the gear 84 due to the engagement of the rack 81 and the gear 84, and further the rotating shaft 83 rotates, so that the reel 85 rotates and winds the pull rope 86, and further the electric fan 72 moves leftwards, in addition, the pull rope 86 contacts and generates friction with the fixed pulley 87, the fixed pulley 87 stops rotating due to the friction force, when the connecting plate 41 rotates upwards to the home position, the rack 81 rotates the gear 84 reversely to the home position, further the reel 85 rotates reversely and discharges the pull rope 86, and meanwhile, the fourth spring 73 moves the electric fan 72 back to the home position rightwards, so that manual movement can be replaced, and time and labor are saved.

The student manually makes the movable block 94 slide upwards on the third slide rail 92, the fifth spring 93 changes from the initial state to the compressed state, then the student can put a towel or a coat between the third connecting rod 91 and the movable block 94, then the movable block 94 is released, the fifth spring 93 is still in the compressed state, the movable block 94 clamps the towel or the coat by the elastic force, so that the student can conveniently place clothes, then the student starts to do sit-up training, after the student finishes the training, the student pulls out the towel or the coat from between the third connecting rod 91 and the movable block 94, the fifth spring 93 resets from the compressed state, and the elastic force makes the movable block 94 move back to the original position.
