I was a good middle-distance runner, did some competitive road cycling with moderate success, and did martial arts for a long time. I’ve also done some long-distance walking, but never with heavy packs. I hate those.

I took an extended break from the martial arts, but recently returned to a related activity. My mind knows what I should be doing, but my body isn’t always able to deliver. But that tells me where I need to train in order to get back to it, and the training has been yielding results.

I had always assumed the memory was in the cerebellum rather than in the muscles themselves, though. That’s where fine muscle coordination happens. So this is an interesting finding.
