The third and fourth basic movements in Yoshinkan Aikido have the name Hiriki No Yosei, which is translated in English as "Elbow Power", so named for the prominent role the elbows appear to play in the movement. The Ni (#2) version combines a strong and deep shift from stance to stance, with a "drawing up a sword" motion, and then cutting back down as one shifts back. The motion is found in techniques such as Shihonage (All-direction pin) and Kotegaeshi (Outward-wrist), and is found in subtle ways in many Katate Mochi (One-wrist grasp) techniques.
Like the other basic movements, Hiriki No Yosei Ni has three forms: Solo, with Partner and with Sword. The solo version is shown in the second half of the video above, starting at 0:34s.
