Description

Technical Field

[0001] The invention relates to the technical field of sports equipment, in particular to a strength training device for physical exercise. Background Art

[0002] Physical exercise refers to physical activities that people choose based on their physical needs, use various sports methods, and combine natural forces and hygiene measures to develop the body, improve health, enhance physical fitness, regulate the mind, enrich cultural life and manage leisure time. It is generally divided into horizontal bar, parallel bars, dumbbells, etc. The horizontal bar is usually used for pull-ups and other movements to exercise the upper limbs, back and core muscles.

[0003] However, when performing pull-ups on existing horizontal bar equipment, the entire center of gravity needs to be placed above the horizontal bar. This movement process will cause the horizontal bar to shake slightly. After performing pull-ups for a long time, there may be a safety risk of the horizontal bar breaking or loosening, affecting the life safety of personnel. At the same time, a large amount of sweat will be generated on the hands during training, and the sweat will cause the friction of the hands to decrease, resulting in signs of falling off, causing harm to the trainees.
