@Bernard Rose Training back then was tough, and I think you were at it even before me, so I can only imagine. The things we were asked to do, even as kids, just the dehydration alone, makes my toes curl now. I remember training with John Mullin sensei once, putting in 200% like I always did. He told me I would not be able to train like that the next day. I had no idea what he meant until we lined up. Five of us counted 100 reps of a three-part combination, then we started on other combinations with the same 500 reps. We did that for an hour. I reckon we hit around 2,500 combinations. Then several of us called out our favourite advanced kata and ran each of them twice. The lesson was about relaxation, core-driven technique, and removing unnecessary movement. I repeated a similar session on my own each week for months afterwards. It completely changed how I train, especially now at 52. I no longer train like I am 18. I train to preserve my body. After tearing my meniscus last year, I have learned not to push through. It is about resting, healing, and coming back with a renewed mentality. I will be back training in a couple of months, and when I do, it will be on my terms.
