Sharing a building with a gym means I see training-related back complaints early, often the same week they start rather than three months later. The pattern is consistent enough to be worth writing down: most of it is mechanical, most of it improves with movement rather than rest, and a small minority needs a proper look before anyone loads it again.
Nothing here is a diagnosis, and it is not a substitute for being assessed. It is what I would tell someone standing in front of me before I had examined them.
The reassuring pattern
Pain that came on during or after a session, sits in the muscle either side of the spine, feels stiff in the morning and better once you move, and is roughly symmetrical. That picture is common, it usually settles in days to a couple of weeks, and complete rest tends to make it last longer rather than shorter.
What helps is usually load management rather than avoidance: same movements, less weight, more control. Working with a coach of your own for a few weeks is the cleanest way to do that, because someone is deciding the load with you instead of you guessing between sets.
The pattern worth getting looked at
Pain that travels below the knee, numbness or pins and needles, weakness in a foot or leg, night pain that wakes you, pain following a genuine fall or impact, or anything involving bladder or bowel change. That last one is an emergency, not a booking.
None of that means something terrible is happening. It means the question is no longer "how much should I lift on Thursday", and guessing is not the right tool.
Why I would rather you kept training
The single most reliable predictor of a back that keeps hurting is a back that stopped moving. Deconditioning is not neutral. It is why I send people back down the corridor rather than telling them to rest for six weeks, and why lifting with a coach watching is usually a better prescription than a month off.
Teri and I talk about this constantly, because the handover in both directions is the whole advantage of being in one building. If you are not sure whether what you are feeling is sore versus injured, I wrote that one out properly. If the trigger was a desk rather than a barbell, what sitting all day does to your hips is more likely to be the article you want.
