Which command indicates "At Ease" in martial arts?

The command signifying "At Ease" in martial arts is "An Ja." This term emphasizes a state of relaxation while still maintaining awareness and readiness. In martial arts training, commands play a crucial role in guiding students on when to be alert and focused, and when it is appropriate to relax and gather oneself. "An Ja" specifically instructs practitioners to take a moment to breathe and reset while remaining in an alert posture, preparing them for the next set of instructions or techniques.

Understanding the context of other commands helps clarify why "An Ja" is the correct choice. Other options may reference different positions or postures used in martial arts, but they do not communicate the concept of momentary relaxation combined with preparedness as effectively as "An Ja." This highlights the importance of recognizing specific terminology in martial arts and their corresponding implications for mood, focus, and readiness during training sessions.
