Description

Technical Field

[0001] The utility model relates to the field of fitness equipment, in particular to a pedal type barbell rack. Background Art

[0002] With the progress of society and the development of science and technology, people pay more and more attention to health. This improvement in health awareness has led more and more people to actively participate in various fitness activities, hoping to improve their physical fitness, enhance their immunity, and achieve the goal of physical and mental health through exercise.

[0003] In this context, traditional barbell racks seem to be somewhat powerless. Their functions are usually relatively simple, and they can only provide limited exercise methods, such as simple weightlifting and squats, and cannot meet the diverse exercise needs of users. For example, some people may want to exercise different muscle groups through different training methods, or hope to improve the training effect by changing the training intensity and method, but traditional barbell racks often cannot meet these needs.

[0004] At the same time, although some existing multifunctional fitness equipment has improved functions and can provide more exercise methods, its structure is complex, occupies a large area, and is not easy to adjust and operate. This not only limits its scope of use, but also reduces the convenience of use for users. For example, some large multifunctional fitness equipment may only be used in professional places such as gyms, and require professional coaches to guide, which undoubtedly increases the difficulty and cost of use for most ordinary people. In view of this, we propose a pedal-type barbell rack. Utility Model Content

This improvement in health awareness has led more and more people to actively participate in various fitness activities, hoping to improve their physical fitness, enhance their immunity, and achieve the goal of physical and mental health through exercise.

[0032] In this context, traditional barbell racks seem to be somewhat powerless. Their functions are usually relatively simple, and they can only provide limited exercise methods, such as simple weightlifting and squats, and cannot meet the diverse exercise needs of users. For example, some people may want to exercise different muscle groups through different training methods, or hope to improve the training effect by changing the training intensity and method, but traditional barbell racks often cannot meet these needs.
