Has anyone tried corrective exercises for mobility issues?

I've been trying to improve my mobility and fix a few movement issues that seem to come back even when I exercise regularly. I'm especially interested in exercises that focus on posture, flexibility, and muscle imbalances rather than just building strength. I came across people discussing the value of Corrective exercises lake worth and was curious whether anyone here has experience with this type of training. What kinds of exercises helped you the most, and did you work with a trainer or figure out a routine on your own?
