Once the students are properly lined up and waiting, the instructor comes onto the mat and sits facing the shomen. These exercises involve various body movements which stress the movement of one's center, while maintaining a completely stable posture. The teacher then instructs by demonstrating techniques with a partner. Once sensei has finished demonstrating, students pair up to practice what hey have been shown. When the instructor claps, this signals the students to sit down while instruction continues.
Students remain seated until the instructor has left the mat.
Bowing is part of the tradition and reflects the proper state of mind required when practicing Aikido. It signifies respect for one's partner or teacher and is not in any way a religious act. Always bow upon entering the dojo, and upon entering and exiting the mat area. When practicing with a partner, bow once at the beginning of your practice - you do not need to bow again until you change partners. Too much bowing slows down the class and frankly looks silly.
