I don't want you to miss out on this, so I'll bump this post up from time to time.
Make sure you check it out the free resources at The Martial Arts Vault as soon as possible!
Once inside The Vault you will find lots and lots of free, cool and very useful (as in educational) stuff about self-defense and the martial arts.
You may also find the occasional rebates to my e-books etc in addition to the free things. Enjoy!
