resistance = any mechanical force that tends to retard or oppose motion
isn't it fairly academic as resistance implies knowledge or foresight? one can resist and block ikkyo as long as one knows that ikkyo is coming. the true question is- can Joe blogs can defend/ counter/ resist if he does not know what is coming?
surly to argue to opposite is to argue the nature of aikido????
as according to my master teacher- "to meet the spirit and the way". To encounter the path of non- resistance. surely if an opponent resists, change the technique?
