Arm Attacks

There's really only 6 ways to hurt someone's arm and only 3 of those are legal across all belt levels
1. Wrist Lock- palm down
2. Wrist Lock- palm up
3. Elbow Hyperextension
4. Bicep Slicer
5. Shoulder Lock- hand up
6. Shoulder Lock- hand down
You can take your arm and test the mechanics of the positions it moves in and those will function the same across all humans. If you can place someone's arm in one of these six positions that is the entirety of arm locks in grappling. It is more important that you understand how anatomy works than that you memorize every individual technique independently. If you can begin to connect the moves that you see through commonalities, it opens up what is possible in your BJJ game.
