Description

Technical Field

[0001] The present invention relates to the technical field of sports equipment, and particularly relates to a sports equipment for arm muscle exercise and its usage method. Background Art

[0003] Sports equipment for arm muscle exercise refers to fitness tools specifically designed to strengthen, shape, or rehabilitate arm muscles, including biceps, triceps, forearm muscle groups, etc. Such equipment helps users specifically stimulate target muscle groups by providing resistance, stability, or specific movement trajectories, achieving strength improvement, muscle dimension increase, or function improvement. It includes various types. Free weight equipment is equipment that provides resistance through gravity, such as dumbbells and barbells, with free weight adjustment and flexible movements; Fixed trajectory equipment is equipment that restricts the movement path through mechanical structures, such as preacher benches and triceps presses. The movement trajectory is fixed, reducing compensation. It is suitable for beginners or when specific muscles need to be isolated for training; Multi-functional comprehensive equipment is equipment that combines multiple training functions, such as power racks and Smith machines. It provides resistance from multiple angles and in multiple ways. It is suitable for full-body compound movements or advanced training; Special training tools are equipment for specific functions or rehabilitation needs, such as hand grippers and wrist strength trainers. They are highly targeted and suitable for special training or rehabilitation. The equipment forces the arm muscles to overcome external forces through weight, elastic force, or mechanical resistance, achieving overloaded stimulation and promoting muscle growth. The equipment can simulate various movements to meet different training goals. Among them, the preacher bench, as a lightweight fitness equipment, can meet the fitness needs of gyms and also the home fitness needs. After adjustment, the preacher bench can meet various exercise needs for arm muscle exercise.

[0004] Chinese Patent Publication No. CN221732273U discloses a multi-functional fitness device, including a base, a fan-shaped plate, a seat plate, a footrest rod, a backrest plate, and a backrest support rod. By connecting the upper end of the backrest support rod to the backrest plate, clamping its lower end between two fan-shaped plates and rotatably connecting it to the fan-shaped plate, and making its rotation axis extend in the left-right direction. When the backrest support rod is in the first working position, the backrest support rod extends in the up-down direction, and the backrest extends obliquely from the front lower direction to the rear upper direction, so that the backrest and the seat plate can be combined into a preacher bench fitness device, and the backrest and the footrest rod can be combined into a hyperextension fitness device; when the backrest support rod is in the second working position, the backrest support rod extends obliquely from the front upper direction to the rear lower direction, and the backrest extends obliquely from the front upper direction to the rear lower direction or extends in the up-down direction, so that the backrest and the footrest rod can be combined into a squat machine fitness device, thus realizing three fitness functions and being able to meet the needs of performing various posture exercises in a family room, with a wide range of applications. After the existing preacher bench in the gym is used, sweat stains and bacteria will remain on its surface. Using it directly without cleaning will increase the risk of skin infections, such as athlete's foot and folliculitis, affecting the physical health and usage experience of users.
