Ryō ashi zuri 両足吊り
Any suspension in which both legs are lifted together, as distinct from kata ashi zuri, where only one leg is suspended.
Ryō ashi zuri (両足吊り) combines ryō ashi, both legs, with zuri, suspension. Shibari Study defines it broadly as any suspension tie in which both legs are suspended together, so it describes where the lift is placed rather than one fixed position. It contrasts with kata ashi zuri, in which a single leg is lifted.
