I'm trying to remember the specific Japanese name of a common posture/stretch I used and heard of in Aikido during training and warming-up.
Basically it was called by our sensei "standing and crouching". You would start standing straight as you would normally, with a light posture and square shoulders, then "lower your butt to your heels" by folding your knees, while keeping the rest of your body straight. You'd try to go as low as you can whilst relaxing and resting you weight.
As you can imagine it would stretch the back leg and calf muscles.
I found it simple and useful to execute whenever I'm forced to stand for long bouts of time, waiting for a bus or in a lift for instance.
My sensei used the Japanese word for it and I can't remember it.
Any idea what this posture is called in Japanese?
