Soreness is the only pain that shows up to say you did something right.

Most pain is a warning and this one is a receipt. The ache two days after a hard session is the sign of tissue rebuilding, which is why it feels oddly satisfying in a way that a twisted ankle never does. It is worth knowing the difference, because the same attitude applied to sharp pain will get you hurt.

Learn your own two signals: the dull ache that fades over a couple of days, and the sharp thing that says stop now. Respect the second one immediately. And when the first arrives, take it as evidence rather than as a reason to do more tomorrow.
