Re: Tsuki Iriminage - Step back hand grab
You cant grab a punch. Itīs as simple as that.
What you can do is to make contact and affect the balance of uke. Itīs very important to move backward with the intention still directed forward, you dont want to have the feeling of escaping or fleeing. While moving backwards, cut down (in your own center) along the arm of uke. The cutting motion goes from the shoulder to the wrist and starts making contact along the biceps. Drop your hips during the cut and transfer the drop to the arm of uke. If this is done successfully you have compromised the balance of uke and created a small opening.
Remember to be quite relaxed in your arm during the cut and to move backwards in a small angle.
