“I fear not the man who has practiced 10,000 kicks once, but I fear the man who has practiced one kick 10,000 times" 
 Quote:  Bruce Lee
 
Repetition of fundamental basics in the martial arts is often spoke of but not always followed. The  basic movements are usually the foundation of your training.  The better you are at the basics, the better you will be at the more advanced movements.  Also, if  you consider the high percentage techniques, they are usually the simple basic moves that you learned first on your journey.  The good thing about this is since you are training to apply them in a stressful environment (a fight), basic and simple is usually easier to use to become effective. 
 
The more I train, the more I am brought right back to the basic moves I learned when I started in the arts.  And one thing I notice is that through great repetition comes great understanding of those basics and the ability to apply them in many different situations while under greater stress.

So, the next time you hit the mat with your training partner, don't forget to put in some time on those fundamental basic moves.
