Description

Technical Field

[0001] This invention relates to the field of fitness bench technology, specifically a fitness bench for exercising the hip joint and perianal muscles. Background Technology

[0002] Currently, there are few specialized exercise benches for the hip joint and perianal muscles. Conventional fitness benches cannot achieve multi-directional rocking, rotation, and extension, making it difficult to accurately train the muscles around the hip joint and perianal muscles. Furthermore, most existing fitness benches are of fixed specifications, which cannot adapt to people of different body types and exercise needs, resulting in significant limitations in their use. To address these issues, this invention designs a fitness bench with a simple structure, multi-directional movement, and support for multiple size adjustments. Summary of the Invention

[0003] The technical problem solved by this invention is that existing hip joint and perianal muscle exercise stools cannot achieve multi-directional movement coordination and have fixed specifications and poor adaptability. The core improvement is to achieve three-dimensional movement coordination of rotation, extension and sway through a four-layer composite structure design of a hard seat plate (1.), a metal turntable (2.), a spring assembly (3.), and a hemispherical hard support base (4.). Moreover, the material, size, and connection method of each component can be flexibly adjusted according to the user group, ultimately achieving precise exercise goals and improving stool adaptability.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is as follows: a fitness bench for hip joint and perianal muscle exercise, comprising a hard seat plate (1.), a metal turntable (2.), a metal spring assembly (3.), and a hemispherical hard support base (4.). Each component is fixedly connected in the vertical direction by stainless steel reinforcing screws (6.). The metal turntable (2.) achieves 360-degree rotation in the horizontal plane, the metal spring assembly (3.) achieves elastic extension and contraction in the vertical plane, and the hemispherical hard support base (4.) achieves multi-directional swaying of the fitness bench through the smooth arc-shaped contact surface at the bottom (5.). The specifications of each component can be flexibly adjusted according to human body shape and load-bearing requirements.

[0005] The beneficial effects of this invention are as follows: it achieves three-dimensional coordinated movement through composite structure design, which can accurately exercise the muscles around the hip joint and the muscles around the anus, and improve muscle strength and flexibility; each component supports multiple size adjustments to adapt to people of different body types and different exercise needs, solving the problem of fixed specifications and limited use of existing stools; the stool has a simple overall structure, is easy to operate, and is suitable for various scenarios such as home and gym.
