What soreness actually means
Delayed onset muscle soreness is the most misread signal in training. It correlates with novelty far better than it correlates with progress.
- A new exercise
- A long time off
- Lots of lengthened, eccentric work
- A big jump in volume
- More weight than last time
- More reps at the same weight
- Better technique
- Consistency across months
What DOMS is
Soreness appearing twelve to forty-eight hours after training, most reliably after unfamiliar work and after movements loaded in a stretched position.
It reflects mechanical disruption and the inflammatory response to it — a repair process, not damage in the injury sense.
Why it is a poor progress signal
It fades as you adapt. The same session that wrecked you in week one produces nothing by week six, and yet week six is when you are actually getting stronger.
You can be extremely sore from a session that was mostly novel and unproductive, and completely unsore from a session that added weight to your best lift.
Chasing soreness leads to constant programme changes, which is exactly what prevents progressive overload.
What helps
Time, mostly. Two to four days for the worst of it.
Light movement — walking, easy cycling — feels better than complete rest for most people.
Sleep and adequate protein, which is the same answer as for everything else here.
Ramping volume gradually rather than jumping, which prevents most of it in the first place.
When soreness is not soreness
Sharp, localised or joint-centred pain is not DOMS, and neither is anything that appears during a set rather than a day later. That is worth stopping for and, if it persists, worth a professional opinion.
Questions
Does soreness mean a good workout?
No. It mostly reflects how unfamiliar the work was. Progress is measured by load, reps and consistency, not by how sore you are the next day.
Should I train while sore?
Mild soreness is fine to train through, particularly for other muscle groups. Severe soreness usually means the last session was too big a jump.
How do I get rid of DOMS faster?
Light movement, sleep and adequate protein. Nothing removes it quickly, and preventing it by ramping volume gradually works better than treating it.
