CROSS-REFERENCE TO RELATED APPLICATIONS

[0001] The application claims priority to Chinese patent application No. 2025205476696, filed on Mar. 26, 2025, the entire contents of which are incorporated herein by reference.TECHNICAL FIELD

[0002] The utility model relates to the field of fitness equipment, in particular to a fitness device.BACKGROUND

[0003] In the field of fitness equipment, rail-type exercise devices (such as kicking exercisers and slide rail type strength exercisers) achieve muscle exercise through the reciprocating sliding of a sliding seat on a rail and elastic resistance. Existing rails are mostly inseparable, resulting in large space occupation for transportation and storage and high maintenance cost for overall replacement in case of partial damage. Chinese patent document No. CN1218703A discloses a fitness device, characterized by comprising: a guide rail; a track carriage capable of sliding on the guide rail; and a resistance device for providing unidirectional and variable resistance to the track carriage. When a force is applied to the track carriage sufficient to overcome the resistance force of the resistance device, the track carriage is capable of sliding along the guide rail in a first direction. When the force is removed, the track carriage is capable of sliding along the guide rail in a direction opposite to the first direction.

[0004] The guide rail in the above solution is inseparable, resulting in large space occupation for both storage and packaging.SUMMARY

[0005] The objective of the utility model is to provide a fitness device that occupies small space for packaging, transportation, and storage.
