So you're saying that I should practice to not land on people?
The point of practicing is muscle memory and to attain a reactive state. If I am repeatedly training to not land on someone in practice then THAT IS WHAT IS GOING TO BE ENGRAINED IN MY MUSCLE MEMORY... that's how it works folks. That is the point of practicing.
Practicing to keep from landing on someone is like practicing Juji Gatame with ukes elbow up so you don't hurt them. It's rediculous. You don't practice it that way because that is not what you want engrained into your head.
That being said, I think I see where we're having a miscommunication. I am not all for hurting people and going mental on the practice floor. However I AM all for practicing exactly how you want to perform in contest due to muscle memory, and no one will ever convince me otherwise. The problem is that my throw is a straight driving Harai, and unles syou have several people to help hold uke up, it's impossible to train it how it is throw in competition due to body positioning. When I enter for this throw, my body is at at least a 45 degree angle, and I am going to hit the mat with my head and shoulder regardless. You CAN'T practice this without throwing it full force.
You enter for it, and it is going to be a hard fall... that is all there is too it. When people are available, then we can get 2 or 3 people to hold Uke up so he doesn't have to take the fall, but unfortunately there is not always enough people available.
Landing on people might suck, but it is certainly not bad manners or bad technique. It is infact fantastic training because I will instinctively grab you by the fucking head and hammer you into the ground without thinking about it. I have less than 5 degrees of seperation between my instructor and the founder of Judo. I have trained with the coaches of Olympic champions and Olympic competitiors themselves. That is how they train, that is how I have been trained to train, and that is how I will always train others. You throw a punch just like you would in a real match, you throw an armbar just like you would if you were in a match and you throw people just like you would if you were in a match. Anything else is a waste of time and effort.
