I took an aikido class at junior college years ago for easy credit (I'd had it before). It was laughable. You didn't even really need to touch the people who were seniors in the class before they would go flying. Had a woman-wants-to-be-a-man for the assistant instructor, who inflated her ego by having these cooperative colored belts latch on, then dive around in circles while not releasing her wrists. Being respectful, I waited for the end of the semester. Being a smartass, I raised my concerns with the sensei at the end of the semester. We discussed, and settled on a couple of different experiments.
1. I'll throw a lead-hand finger jab to the center of your forehead, and bruise you right in between the eyes, with the understanding that moving to the right or left justa bit changes the outcome dramatically; you do to me whatever you can/want.
2. I'll grab your wrist, but won't cooperate. If you can't throw me, I don't go down. Using brute force, balance accomodations, and eventual release, your stuff won't cut it.
3. I'll come at you with a bull-rush tackle and takedown, and you can do whatever you can/like to stop or redirect or counter me.
4. I'll come at you with a short shinai in FMA stick-fighting style (he wore a scooter helmet for this one), and you defend any way you like.
5. I'll come at you in full ball-bat style swing with a full-length shinai, and you can defend any way you like.
The only one he did well on was the full-length shinai swung at him like a ball bat...he deftly intercepted me, and dumped me on my unceremonious butt. Everything else? Left him shaken up. He had not realized how dependent he had become on cooperative uke for successful completion in dealing with an attack. The red raw spot between his eyes from the finger jab was testament to what he was not accostumed to recieving...an honest attack by his training partners.
Bumped in to it again in the ninjutsu segment at an MMA camp. Teaching ichimonji, where you step off the line of attack from a straight punch, and counter-strike the extensor compartment of the forearm of his extended strike. Put to it at true speed with ill intent, they couldn't pull it off. 3rd try, the guy finally just backed up (changing maai).
Train hard, or get off the mat.
Just a thought.
