Description

Technical Field

[0001] This utility model relates to the field of fitness equipment technology, specifically to a fitness equipment for shoulder exercises. Background Technology

[0002] Fitness refers to activities involving various physical exercises and activities aimed at improving physical fitness, health, physique, and athletic performance. It includes aerobic exercise, strength training, flexibility training, and many other forms, all designed to promote physical and mental well-being. Nowadays, more and more people enjoy fitness activities, and the government strongly advocates for national fitness to enhance physical health. There are many ways to exercise. Some people like to use arm exercisers to strengthen their arms; these are fitness machines that use bending springs or hydraulic devices to train upper limb strength (such as forearm wrist flexors, chest muscles, and shoulder and back muscles). Others prefer to use large machines in gyms to stretch their arms and strengthen their shoulders. However, these methods are relatively limited, requiring the coordination of both arms to achieve the desired effect. They cannot target individual arms and cannot be done anytime, anywhere, thus failing to meet the fitness needs of the market.

[0003] Therefore, existing fitness equipment technology needs further improvement to address the above issues. Utility Model Content
