When training is performed on the practice stand 4 alone, the practice stand 4 can be fixed on the land surface alone for practice, and the user only needs to fill the head tank 46 and the body tank 43 with water:

as shown in fig. 10: when the head and the upper part of the body of the user are respectively in the head pool 46 and the body pool 43, taking the example that the swimming floating plate in the head pool 46 is only used as the swimming floating plate in the body pool 43 and the swimming floating plate in the head pool 46 is removed, the body of the user is supported by the buoyancy of the swimming floating plate in the body pool 43, the user can obviously feel the up-and-down floating of water due to the action of the vibration device 47, and the head can keep the whole comfort only by carrying out corresponding ventilation operation; fig. 10 shows the user in the head-closed state in the water in the head tank 43, with the left hand facing backwards, the back of the hand extending straight up parallel to the body, and the right hand sliding torsion device 48 effecting a hand stroke curve movement on the compression of the second spring 483, fig. 11 showing the above process;

when the user goes to fig. 12, the user is in the water with the head side extending out of the head pool 43 for ventilation operation, at the moment, the right hand stretches backwards and upwards to be parallel to the body, the left hand drives the torsion device 48 to realize the second compression spring 483 to perform hand stroke curvilinear motion, and the whole practice of free swimming is repeatedly completed.

It is worth noting that: in the above process, the user optionally kicks the second leg plate 45 with the leg in the corresponding stage one, two or three according to the self-training condition and habit, and under the condition that the first spring 49 connected with the first leg plate 44 is stressed, the second leg plate 45 is stressed and bent, thereby realizing the exercise of leg water-beating.

It is to be understood that the above description is not intended to limit the present invention, and the present invention is not limited to the above examples, and those skilled in the art may make modifications, alterations, additions or substitutions within the spirit and scope of the present invention.
