active stabilisation exercices for the abs do wonders to completely and permanently eliminate low back problems in many cases if done properly and for long enough(3 months to a year, 3-5 times a week) and the maintenance work like once or twice a week can be done with only 1 set of 1 or 2 exerices if you’re an athlete training seriously already.
Reinforcing the ”so-called” problem area, in this case the low back, is not always the answer and will sometimes worsen the condition.
