This isn't a big deal--I've always sort of enjoyed the soreness that comes after a hard workout, as evidence I really worked out. I never understand when people post complaints: "Oh, I lifted weights yesterday and now my arms are s-o-o sore..."
As I've moved into my 60s, though, the pattern has changed. I've typically been a little sore the morning after, but now it's often delayed a day or even two. It's a recognized phenomenon, with an official acronym, DOMS, and not an issue at all. I'm just wondering if anybody else has experienced it. Sunday I moved two yards of gravel and two of topsoil across my yard with a shovel and wheelbarrow, unaccustomed labor for me. Felt fine Monday; Tuesday I'm a little tender. But enjoying it.
