Description

Technical Field

[0001] This utility model relates to the field of home fitness equipment. Background Technology

[0002] With the improvement of material civilization, people have devoted more enthusiasm to the pursuit of health and physical beauty. As a result, a large number of fitness and shaping products have emerged in the market. Fitness products are divided into aerobic and anaerobic exercise, and also into commercial and home types. Commercial fitness equipment focuses on one machine for one purpose, emphasizing force lines and trajectory; while home fitness equipment emphasizes multi-functionality, using the combination of components to achieve multiple uses. Taking an anaerobic home fitness machine as an example, based on a full-frame squat and bench press rack, it adds functions such as a pull-up bar, parallel bar, and Smith machine with a fixed trajectory, and adds weight blocks and a traction distribution system, which can realize mechanical movements such as flyes, lat pulldowns, butterfly chest presses, chest presses, and seated rows.
