What DOMS is

Delayed Onset Muscle Soreness is the soreness that appears 24 to 72 hours after a workout, particularly one involving unfamiliar exercise or eccentric loading (downhill running, new lifting exercises, new bike position).

Mechanism: microscopic damage to muscle fibres triggers an inflammatory response. The soreness peaks at 24 to 48 hours and resolves within 3 to 7 days.

What DOMS tells you

You did something new that your body had not adapted to.
You did more eccentric work than usual.
You loaded a muscle group that was unaccustomed.

What DOMS does NOT tell you

It is not a fitness marker. Athletes can be very fit and rarely sore, or rarely fit and frequently sore.
It is not a damage signal that requires intervention. Most DOMS resolves on its own.
More DOMS is not more adaptation. Severe soreness often correlates with insufficient recovery, not better training.

Logging DOMS in the Hub

Use the soreness field on daily wellness. The 1 to 10 scale captures DOMS reasonably well.
soreness >= 8 fires a concerning flag (see Concerning flags explained).
Persistent soreness above 6 for 4+ days suggests inadequate recovery or new overload.

What to do when DOMS is bad

Easy aerobic movement: helps clear, does not make it worse.
Hydration and protein: support recovery.
Sleep: most important variable for recovery.
Compression / ice / massage: small benefit, not required.
Anti-inflammatories: avoid during the adaptation window (24 to 72 hours post-exercise) because they may blunt the adaptation. Acceptable for pain control after.

What to NOT do

High-intensity training on top of severe DOMS is a recipe for injury.
Static stretching of badly sore muscles can produce micro-tears.
Self-diagnose persistent soreness as DOMS. Soreness that lasts more than 7 days or that is localised to one joint is probably not DOMS; refer to medical.
