In lecturing us on resilience and rooting, he had two stout students (one was my frequent partner from Kyushu) each grab a wrist so that one grabbed Ueshiba's left wrist with his right hand while the other grabbed Ueshiba's right wrist with his left hand. Thus, all three men were on a line looking at us. Then the master asked them to really bite in with their grips which they did, bending their knees a bit at the same time.
Then quicker than a flash, Ueshiba bent his knees and sent his ki to his wrists. The wrists didn't move much but his students simultaneously snapped skyward in unison.
