So, it was aikido, but better? You mention his connection with the ground, and ability to easily perform techniques against profoundly resistant partners. Can you go into more detail?
Most importantly, was he able to convey to you how he did those things? Did he teach you what to do, and have you been able to apply what you were taught effectively?
I am interested. If I had the free time from work, I'd check out a seminar for sure. Folks I know and respect are saying good things about the folks teaching these seminars, but are not saying that they have taken useful stuff out of the seminars and applying the techniques in their own practice. So I am not fully sold on the idea yet. Can you provide anything that would tip the balance?
Good questions. I don't want to speak out of place, but he did provide us with specific exercises to develop these "abilities". We are in the process of joining the Ginjukai as a study group (consisting of both Aikikai and Dentokan members) to try and further develop these skills under Mr. Popkin's guidance.
While I most certainly won't claim to have developed any "aiki" skills after a mere two days or introduction/practice I find myself at a place where:
1. I know it isn't BS
2. It can be clearly applied to my Jujutsu waza (or more accurately my waza applied to it)
3. My waza will always be severely lacking without it
As I mentioned before I was completely skeptical of the whole IP/IS argument. I expected Mr. Popkin to simply have polished, excellent Jujutsu. It was much more than that. I think the entire weekend he only showed us one kata from Daitoryu. As much as I hate to say this, it has to be felt.
Interestingly I felt more correlation between what Mr. Popkin does and my Iai than I do with my current Jujutsu practice.
