Your Aikido experience will depend on who is teaching and who your training partners are. I tried a few dojos and it’s not for me. However, I would make an exception if we’re talking about Bruce Bookman’s dojo, because Bookman has a background in both western boxing and BJJ, and has spent decades incorporating lessons learned from those other arts into his Aikido classes. He seems sincere in his mission to make sure his students practice against skilled boxers’ punches and are comfortable with ground grappling. Also, he and Ellis Amdur worked out a system for jo (the Aikido staff) incorporating ideas from koryu bujutsu (old Japanese war arts) so that people who practice that jo system can use a broomstick or other available stick-like implement on the street if needed.
Taikyouku Budo is a modern art that began as a re-imagined Aikido, presented by Ellis Amdur to a particular Aikido dojo by request. Amdur re-imagined Aikido as 5 vectors, like the numbers of a clock, and introduced some other innovations, like the Chinese Six Harmonies (jin and dantian/“the suit”). That dojo ended up rejecting Amdur’s concepts, but some members adopted it and branched off to their own school. They gave it its present name instead of Aikido because it was deemed to have evolved into its own art. Today, TB incorporates grappling in all ranges (Aikido uses arms-length grappling, not body to body like Judo and Sumo), strikes from the shoulders, hips, etc. They started working in the Amdur-Bookman jo routine but it’s an ongoing process. Anyway, TB training often includes counters to wrist locks, arm locks, etc., counters to counters, and controlled improvisation which starts with “uke” attacking “tori”, “tori” applying technique to “uke” (like in Aikido), then quickly morphs into uke attempting a reversal or other counter on tori, tori responding, etc. Training also includes sumo-like standup grappling like one game where two trainees fight to achieve double under-hooks first.
