I’ve been working out more and more recently. Today, I measured my resting heart rate for the first time in a while, which is a rough measure of progress. It was 54bpm. This is quite low! When I was in the army, I had a resting heart rate in mid-40s. I doubt I will ever get it that low again, but wouldn’t be surprised to hit an even 50bpm when I get fitter.

Other than being sore, I’d forgotten how much better one feels when fit. Thinking is even improved a great deal.
