What always amazes me with many of these goshin waza techniques is how fairly subtle changes in the techniques lead to huge improvements in their effectiveness. A small shift in weight distribution, re-positioning of the hands, stepping closer to the opponent etc can suddenly change a weak technique into a strong technique. Many of the self-defence techniques that we do tend to have an overlap with some jujitsu techniques. Luckily for me my training partner (who happens to be my husband) is also a black belt in jujitsu. He is able to talk me through all the little nuances that make a big difference to effectiveness. This extra tuition that I can get from my husband as well as my instructor means that my performance at goshin waza tends to be one of my strong points in karate.
At the end of the lesson we got to demonstrate all our techniques to the class. Being on show like this is always slightly nerve racking but it's good practice for the grading - we'll definitely be on show then! I think the demonstration went okay (apart from the belt and gi problems) though my escapes from lapel grabs still need a bit more work.
Another step closer to shodan.....need to focus on bunkai next.
