Re: YouTube - good or bad for aikido?
I agree, YouTube can be a very useful source for Aikido practitioners.
I've been off the mat for a number of years and was apprehensive about coming back, primarily due to a lack of confidence in my ukemi abilities.
Watching YouTube made me realise I didn't really have anything to worry about, and went back to my first class in 10 years yesterday.
Ukemi was like riding a bike, you never forget - Unfortunatley I'm aching in places I didn't think could ache today!
