Re: Rip body parts off oppounet
A good way to ensure a dismember is to start your attack from long distance, to make sure your attacking body part has enough momentum going into the opponent. Also, of course, extending knees and contracting elbows add extra power to your moves.
I've also seen that it helps to attack at the point of contraction, e.g. the inside of a contracting elbow, or the outside of an extending one. This causes the joint to contract even further, causing it to break off easily from the stress.
