Mary Heiny sensei referred to this as "hauling sacks of potato". she didn't care much for hauling and i don't either. she also mentioned that you should be able to deliver 3 atemi in every technique. for standard irimi nage, i got 2 strikes in: deflect the attack, strike the kidney, strike the head. haven't figure out the third one yet, unless the third strike is the other hand, the one most folks grab for shoulder/collar, using ridge hand strike to the back of the head at the same time the front hand strike the temple, i.e. shear across the neck bone. or could be a hammer strike when uke falling down. luckily i am not a violent man, unless you stand between me and the foods.
