How does one install a chinning bar in one's home?

Several options are available in sporting goods stores that require no installation, the bar fits in a doorway and uses a cantilever support to distribute your weight, others have brackets that you screw into the frame or wall to hold the bar.

These options are far superior to building one from scratch.

There are a number of websites which will give full guidance on how to install a chinning bar in your home including YouTube where demonstration videos can be found.
