Re: Twist and shout
And why aren't pushups or situps, etc. done? They just increase strength, general health, etc., it doesn't matter if strength isn't used in aikido.
Don't you think that the warmup should be in character with the activity itself? If so, wouldn't pushups be practically the worst Aikido warmup possible? When will you use that movement?
I think a good functional warmup can be done in about 5 minutes, if you are using the right methods.
