Hand training device for land breaststroke

Technical Field

The utility model relates to a breaststroke training equipment technical field, in particular to land breaststroke hand trainer.

Background

Breaststroke is a simple and easy-to-learn basic swimming posture, and is a door-entering posture for people to do swimming activities. The training of breaststroke basic actions is carried out on land, the training device is suitable for beginners to master correct postures, and a foundation is laid for next transition to underwater training. During the primary breaststroke teaching process, the arm action posture of a practicer is not consolidated, the muscle of the practicer is tired along with the increase of training amount, and the action is uncoordinated, so that the breaststroke arm action is easy to deform, and finally the arm action posture is inaccurate. Therefore, the utility model provides a land breaststroke hand training device.
