You're trolling, me.
This thread is directed at me for saying I self teach Tae Kwon Do and Ninjutsu.
Teaching yourself how to fight from scratch is impossible. Supplementing your training with DVDs is intelligent.
The DVD that I learn Tae Kwon Do kicks from Is Revolution of Kicking:
But I only learn the kicks from the DVD. I stick to my Muay Thai knowledge to learn how to apply them. I practice application in class, mostly in sparring.
As you can see from the You Tube clip of the DVD, the detail of explanation for this kick is very high. If you stick to their instructions, and also have exstensive knowledge of martial arts already, it can be a useful training aid.
