TECHNIQUE TUESDAY
Ever sat down on the toilet two days after leg day and realized you have to brace your core and grip the sink like it's a max-effort attempt just to stand back up? Congratulations. You've met DOMS.
Delayed Onset Muscle Soreness. The 24-to-72-hour ache that's been blamed on everything from "lactic acid buildup" to "the muscle tearing and rebuilding." Let's clear some of that up.
First myth to bury: lactic acid. Lactate clears your bloodstream within about an hour of training. It is long gone by the time you're white-knuckling the doorframe on Wednesday. It is not the culprit.
What the research actually points to is microscopic damage to the muscle fibers — particularly from the eccentric (lengthening) portion of a lift. Think the lowering phase of a squat, the descent of a curl, running downhill. That mechanical stress kicks off an inflammatory response, and that cascade — not the "tearing" itself — is what drives the soreness you feel.
Now the part that bruises egos: DOMS is not a scorecard. Soreness is not a reliable measure of how good your session was, and it is not required for hypertrophy or strength gains. You can build plenty of muscle with minimal soreness. Trained lifters often get less sore over time thanks to the repeated bout effect — your body adapts and protects against the same stimulus. That's not your program failing. That's adaptation working exactly as designed.
So if you're chasing soreness like it's the goal — stop. Chase progressive overload, quality reps, and recovery. Let soreness be a passenger, not the driver.
