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.
How is your dad's ukemi?
Are you willing to hit him if he doesn't move?
One of the biggest problems with trying out your aikido on non-training friends and relatives is that they aren't really trying to attack you, and you aren't willing to really throw them. There's no energy. But without energy, aikido is nearly impossible.
