Two failure modes, and they are opposites. One person stops at the first twinge and never builds anything. The other trains through a genuine injury for six weeks because stopping felt like failure. Both are avoidable with a short list of questions.
Signs it is ordinary soreness
It arrived a day or two after a session, particularly a new one. It is spread across a muscle rather than at one point. It is worst when you first get up and better once you are moving. Both sides feel roughly the same. It is fading by day three or four.
That is a normal training response, and the right answer is usually to keep moving at a lower intensity rather than to stop. Ordinary soreness gets better with blood flow.
Signs to stop and ask
Sharp pain at a specific point you can put a finger on. Pain that got worse during the session rather than after it. Swelling, a joint that gives way, or a limb that cannot take normal weight. Pain on one side only with no explanation. Anything still there and unchanged after two weeks.
Two weeks is the number I would hold people to. Most training niggles resolve inside that. Something that has not moved at all in fourteen days is not resolving on its own, and another fortnight of hoping is two more weeks of compensating around it.
The middle ground
Most cases are neither. The useful move is to modify rather than to choose between training and stopping: change the range, drop the load, swap the movement for one that does not provoke it, keep everything else. That is a conversation with a coach, and it is why training one-to-one with a coach for a few weeks is often the right call after a niggle.
Conditioning training is usually the easiest thing to keep doing while an upper body issue settles, and vice versa. Almost nothing requires stopping completely. If the area in question is your lower back, back pain on the gym floor goes through that specifically, and sleep and strength progress is worth reading if you keep picking up small injuries, because under-recovery is usually upstream of them, as is conditioning without wrecking your recovery.
