Description
Technical Field
The invention belongs to the field of fitness equipment, and relates to swimming training equipment.
Background
With the increase of the material level, people pay more attention to the physical health and the beauty of the body. Swimming is an effective systemic body-building mode, in particular to breaststroke which has good effects on developing muscle groups of human bodies, strengthening bodies and shaping bodies, can help people to correct certain abnormal body shapes, and can lead organisms and muscles of all parts of the bodies to be evenly and comprehensively developed. However, swimming has high requirements on environments such as temperature, places and the like, the fixed cost of sports is high, and swimming is a sport with high technical requirements, and particularly, a person who does not know the swimming technology can hardly complete the sport. Therefore, various fitness apparatuses for simulating swimming are developed in the market, for example, chinese patent literature discloses a fitness trainer based on swimming simulation [ application number: 201210048830.2], a fitness person leans down on a bearing plate and a hanging frame sticking buckle fixed on a hanging frame, an auxiliary person adjusts arm rods and leg rods to proper lengths and fixes the arm rods and the leg rods by screws, the fitness person sleeves arms and the legs into corresponding arm rod sticking buckles and leg rod sticking buckles, then the auxiliary person buckles all the sticking buckles, and the fitness person can start swimming simulation.
However, the above-mentioned scheme also has the disadvantage that, the body-building person needs another person to assist its body-building training ware of adjusting swimming simulation, can not alone accomplish body-building motion, and in addition, the body-building person lies prone on the bearing plate, and the body-building person supports the effect that can not move and can not reach whole body coordinated motion on the bearing plate, even the improvement mode that partly unsettled still can not avoid this problem.
