But too often the uke "resistance" is not even remotely martial. I call a locked down, resisting uke a "target". A human target doesn't need to be thrown or moved - it is struck or choked instead.
I think it is really bad training for an uke to resist like that regularly. In an actual confrontation, the Aikidoka might very well "feel" bad technique and reflexively "show" the attacker is not doing things "right" by resisting - and promptly get themselves rocked.
