Hello, according to the situation described, it is mostly because of bad exercise methods, which leads to the bad phenomenon caused by strain of waist muscles and soft tissues. In addition, we should also consider some bad behaviors in daily life.
Suggestion:
You can exercise properly every day, but try to avoid long-term bad posture, so as not to cause lumbar muscle strain and affect normal development. Usually, you can do more jumping exercises, play basketball properly, eat more calcium-rich foods in your diet, and supplement some calcium appropriately.
