Re: Why isn't this showing Aikido as effective?
You might note that the lack of "taking ukemi" changes the dynamic in the receiving body; both its structural integrity and how it reacts spacially to the guy trying his schtick on you. Normal people do not act like the trained preconditioned jumpers in the martial arts. And trained fighter?? They're a different planet all together.
If someone opts for video example #1 (yours) as good Aikido, well...have fun
If they mistakenly call it good martial arts? Well...I just feel sorry for them. They are either being deceived or are deceiving themselves. Again though. Its the internet, everyone thinks their opinions are equal, because of their own particular experiences. It may look that way, but it only looks that way.
