I spent some time yesterday reading a bunch of articles on Roy Dean's site www.roydeanacademy.com
This one about strength and technique in martial arts stuck out to me.
In the beginning i thought BJJ had to be "effortless". I was pretty weak when i started and just got mauled all the time. Then i started doing more strength and conditioning and people started saying that i was doing better on the mat and giving them more of a fight. I realized a certain amount of strength is required, this is a combat sport after all. I think the most important thing is that in practice we train in with technique, and don't attributes to patch up technical holes.
I really like Roy Dean's writing. I need to get over to Bend to study with him sometime.
