A penetrating strike is typically used to target which part of the body?

The choice of targeting muscle with a penetrating strike in defensive tactics is based on the effectiveness of such strikes in achieving control over an adversary. Striking a muscle can temporarily incapacitate a person or reduce their ability to move effectively. This is particularly true for larger muscle groups, which, when struck, can cause significant pain and disruption to coordination.

In contrast, targeting other areas such as the head might lead to severe injury or unconsciousness, and strikes to joints could result in long-term damage or fractures. Striking organs could also be highly dangerous and might not provide the immediate effect needed for self-defense or control. Thus, focusing on muscle with a penetrating strike aligns well with the intention of using controlled and effective techniques designed for rapid compliance without excessive harm.
