Ushiro ryote dori Jyuji-garami
Both hands held from behind
Project both your hands out in front of your navel and swing them up. Release your body completely from the front of your partner, grasp both his wrists and cross-twine his arms for a throw.
When pulled backwards by your partner pulling both hands, sink your hips and draw your foot one step back to make your swinging motion easier
Your swinging motion should be in front of your navel
