I was feeling pretty good, so I put in 100 lunges this afternoon. My right shoulder/back region started tingling about halfway through. I was in third hand position. I don’t know if the problem is hand position, body position, repetitive motion, or the time spent holding the sword out in front of me. Up to this point, my back has gotten tingly from sitting down. Leaning against a seat back usually helps.
I’ve noticed that when I do this drill, I square off a lot more than I usually do when I fence. I’m trying to turn sideways to present less of a target (you know, the way I was taught to fence in the first place). Unfortunately, whenever I think about narrowing the available target, then my lunge becomes narrower, or I stop hitting my target.
