There will be times when someone is still attacking you, but not giving you any energy to work with. Real world uke will spoil your technique just as often as dojo uke. Thus, you need some way to get them to start giving you energy."
Is it really possible to attack someone without using energy? If your attacker is stationary are they really attacking you or are they simply stationary? Of course firearms change this situation.
If your uke is not 'giving you energy' then they are not attacking you. Simply freeze your technique in place until they start to move. Sometimes this will leave uke bent over in very awkward position that are unnatural. If they stay there for any period of time, strike them or let them stand there until they cramp. Uke's job is to attack realisitically and freezing in unnatural position is not realistic.
In a real situation uke will always stive to return to a balanced position. This is a conditioned response that we all learn in the first year of life. During a physical confrontation this conditioned response is hightened and uke will respond quicker and more abruptly to changes or perceived changes to his balanced state. When an uke stops their motion in training they are no longer attacking realistically. When was the last time you saw a fight where the initial attacker did one attack then remained bent over and unbalanced or just left their punching arm extended in space indefinetly? Doesn't happen. If your uke's do this they are not helping you train. If someone did this to you in a real life confrontation you would strike them and end the confrontation. Explain this to uke and show them when necessary.
One of the reasons people feel they need to test technique is because they are training with unrealistic uke's who don't attack continuously or uke's that just take a dive. As uke it is our responsibility to affectively train our partner. Furthermore, the opportunity for learning aiki arts is equally great when playing the uke or nage role. Ever notice that people that attack poorly have great trouble learning and those that attack well generally learn faster? This is not an accident.
