If unity is strength – isolation is weakness: Perhaps one of the biggest themes of my Jiu Jitsu is LIMB ISOLATION. As long as one of your limbs is locked close to another limb or to the torso, it will be very and difficult to attack. One of your primary in attacks, particularly joint locks, is to ISOLATE ONE LIMB FROM THE OTHER OR GET IT EXTENDED AWAY FROM THE TORSO. If you can do this consistently, you will submit many people. Whenever an attack on your opponent's limbs is your about the critical aspects of isolation – separate one limb from the other and separate it from the torso. Both are required. Doing so will make strong opponents feel weak. Every scenario will require a different method of limb isolation so I cannot give even general guidelines as to how you will do this every time you grapple, but the goal is easy to comprehend even if the means to it can be complicated. Still, this is a sport where KNOWING WHAT YOU TO DO is half the battle – and that's always a solid in the right direction
