A fat-shedding machine made in 16 years has been in the tool industry for the first time. It is not professional to contact fitness equipment. It uses tool design methods to process more cutting surfaces and more modeling elements. Fitness equipment should belong to the category of household appliances. The household appliance design methods are more material segmentation and the modeling elements are more concise. Originally, I wanted to contact with a new industry, but who knew it was the last song, so I made such a one.
