i was just wondering how long it takes aikido to work because when i tried to perform an aikido technique on my dad he resisted and did not work.
so i was just wondering how long it takes aikido to work in real self defence situation.
In real life you do not decide on a technique and try to make it work. That is known as muscling through, aka fruitless grappling, aka epic fail.
In real life you respond to the attacker's incoming energy and go with what technique presents itself. If the energy changes, the technique changes, as many times as necessary.
