How did you fix it?
It was brought to my attention yesterday that I hunch over a lot

I went to see a local chiropractor, best money I’ve spent this year.

Pilates.

Yoga and pilates.

Lots of 10 min yoga for desk workers type routines. I'd also say a strong cote improves posture which pilates is amazing for

You can also get a brace thing to wear under your clothes that helps you to stop your shoulders sloping forward. A friend who's a yoga teacher recommended one of those.

There are several posture monitors like “Upright” which you attach to your back and vibrate when you’re slouching - I have not tried them but am very tempted to!
