If the back pain is caused by weak postural muscles or a muscular imbalance, then it&#x27;s possible that exercise is correcting those deficiencies.  Your muscles adapt to whatever loads they routinely bear. If you spend most of your time with a supported posture then your postural muscles will naturally weaken over time. I used to have neck and back and knee pain until I started lifting regularly.<p>In my experience, it hurts differently when you&#x27;re damaging your body versus training your muscles. It is possible to seriously injure yourself a little at a time if you&#x27;re not cognizant of this, and it&#x27;s much better to err on the side of caution and progress slower than to ignore your body and risk a serious injury.<p>If we see a study like you say, it will almost certainly fail to control for the confounding effect of a cautious or incautious approach on injury rates.
