If your house has beams, just tap them. If they don’t make a hollow sound, they should be strong enough to support heavy punching bags. You could drill a hole and attach an eye-bolt and mount the bag over it. Another way is to use a mount. You could get them online or at local sports stores. You would need to mount a hardwood board on a set of beams in your house. Once the hardwood board is secured with bolts, attach the mount and load the punching bag. If you have a dedicated room that you’re using as a home gym, a wall mount is a safe option. It has a hangman-like shape, and the vertical part of the mount is secured to the wall with fasteners. The horizontal beam above has hooks and other options to hang the bag. It is recommended to have a height-adjustable wall mount even if it comes at extra cost. After some practice, if you want to practice a flying kick, height adjustment would come in handy.
