Technical Field
The invention relates to the field of shared economy and fitness, in particular to a shared fitness device.
Background
The term shared economy was first proposed by the American society of Texas State university, Markes Filson (Marcus Felson) and the society of Illinois university, Joel. Spaeth in a paper published in 1978 (Community Structure and collectivity consistency: ARoutine activity apparatus); the main feature of the shared economy is the inclusion of an information technology-based marketplace platform created by a third party, which may be a business, organization or government. With the help of the platforms, individuals exchange idle articles, share own knowledge and experience, or raise funds to enterprises and certain innovation projects; the economy is involved in three major bodies, namely a demand side, a supply side and a shared economic platform of goods or services; the shared economic platform is used as a link for connecting supply and demand parties, and the supply and demand parties can trade through the shared economic platform by establishing a series of mechanisms such as mobile LBS application, dynamic algorithm and pricing, mutual evaluation systems of the two parties and the like.
At present, most of traditional gymnasiums need different types of fitness cards such as monthly cards, seasonal cards and annual cards, the fitness cards are expensive on one hand, and on the other hand, people cannot guarantee to frequently go to fitness, namely people do not have time to go to fitness after card running, so that economic loss is caused to cardholders, the cardholders always have worry about incapability of unlocking, and the frequency of fitness of people is influenced by the defects.
Therefore, there is a need to introduce a shared economy into the field of fitness that facilitates flexible fitness by the exerciser.
