I slouch a lot, so my shoulders are a bit rounded at my neutral posture. I have tried to get into the habit of doing wall glides, stretching my chest, doing back exercises, and sitting properly. But after quite a few years of testing strategies, tools, and trying to build consistent habits, I usually manage to get two or three weeks of good progress but then fall back to the usual bad habits and my posture does not really improve.

Do any of you have any success stories about correcting your bad posture? I would like to learn from your success!
