How do you anchor a home made punch and kick bag so it does not swing around when hitting it?

There are several ways to anchor a homemade punch and kick bag to prevent it from swinging around when hitting it. One option is to fill the bag with sand or another heavy material and tie it securely to a sturdy object, such as a tree or a weightlifting rack. Another option is to use a heavy-duty chain or rope to secure the bag to a ceiling or wall mount. This method is useful if you have limited floor space or want to keep the bag out of the way when not in use. You can also use a stand specially designed for punching bags. These stands typically have a base filled with sand or water, which provides stability and keeps the bag upright. In any case, it's important to make sure that the object you're anchoring the bag to is sturdy enough to support the weight of the bag and withstand the force of the strikes.
