Instructional video on Brazilian Jiu Jitsu by Stephan Kesting
BJJ is complicated there's no doubt that!
If you can come to grips and understand this complexity then you'll have a HUGE advantage on the ground. That's because you'll know what's going on and what you should do whereas your opponent won't have the first clue.
It's important to get BJJ right right from the start. When you're starting to learn BJJ you want to make sure that you have rock solid basics. If your fundamentals are strong then you'll go a lot further and progress a lot faster.
Strong basics ensure that there aren't huge holes in your game that can be exploited by a smart opponent!
