To often modern Aikido is not really tested against full resistance. The Shodokan school of Aikido and a few would be Aikidoka attempt to test there Aikido techniques against full resistance. They are usually ridiculed for their attempts and not appreciated for their efforts to prove or disprove a technique. The realities of a fully resisting uke makes the Aikido techniques sometimes unrecognizable, sometimes they simply are too difficult to apply. Maybe some techniques simply just don't work. Some in the Aikido world seem to have a difficult time accepting this reality. The below clip shows the Tomiki Aikido randori (toshu randori). Great to see some real resistance vs demonstration. I would love to hear from those who accept this reality and share your thoughts.
