An explanation of the basic timing for two person drills like Trapping Hands. Standardizing the timing is essential for good quality two person drills. Especially when weapons are involved standardizing the timing makes the practice much safer to bring up to reality speed. When actually using the art for SD or sport it's essential to be aware of the 'pulse' or timing of your opponent/partner, in order to have the skill to apply techniques outside of the standard pulse, by cutting the time in half or more.
