I saw something called "sit-ups/sit-ups" in a fitness equipment store the other day, which is aimed at doing sit-ups. It's convenient to do it alone. The seller said that it is aimed at people who are not from leg press, and it is a professional fitness equipment. The brand they sell is Wismai.

The clerk introduced them to Taobao Mall and Taobao, both of which are for sale. Taobao's store name is "winsml Fitness".

Personally, I think I can go to Taobao first. Taobao has a map, and then you can buy it in a physical store.

This special equipment is very helpful to the body. Of course, it is important to keep practicing abdominal muscles.

I hope it helps you.
