I am often asked about how the techniques in Aikido work and if they would be effective. My answer is always the same, "Of course the techniques are effective and they do work." I saw a video the other day and thought I might share it with you. Irimi style throws where you are entering in can be very effective. In this video you can see what happens when the police officer (nage) moves in on an in-coming person. Note how the person is easily taken down with ease and how little force was used. This is what irimi-nage would look like. https://www.youtube.com/watch?v=pxF1x33S0oE
