Great idea, Slip.
your philosophies on certain things and how they should be done. Right down to a punch you like and how it should be thrown. Things like the best ways to fight a southpaw? how to take away the jab? how to improve your defense? along those lines.
I like that. Plus you can make sub-headings in the OP for a particular thing and write the page so we know where we can look it up.
