TECHNICAL FIELD
The present invention relates to the field of sports equipment, and in particular, to a multifunctional training handle.
BACKGROUND
With the continuous development of society and continuous improvement of the living standard of people, health has become a primary goal of people. Proper physical exercise has also become an effective means for people to improve their health. In the physical exercise, the sports equipment is used for assisting exercise, so that the efficiency of the exercise can be improved, and the scientificity and the safety of the exercise can be increased.
A pull-up is widely used as a core action of back strength training; however, the pull-up is completed by requiring the support of corresponding equipment such as a horizontal bar. The sports equipment such as a horizontal bar occupies a larger space and needs to be firmly fixed to avoid the risk of overturning. With the continuous development and progress of the concept of household sports equipment, horizontal bar equipment that can be fixed between narrow-distance walls and between door frames is gradually developed, and although the equipment is very suitable for household use, the equipment is mainly supported between two walls or between two vertical surfaces of a door frame and is firmly locked after being supported, which ensures that a user will not fall off when performing pull-up action; in addition, the sports equipment such as a horizontal bar have a single function and is inconvenient to carry.
