This problem needs to be approached comprehensively. Pay attention to the shoes you are wearing, as well as your workplace. If you constantly sit with your back bent at the table, no exercise will help. I would advise you to take a closer look at the high tables, they are height adjustable. And you can work either while sitting or standing, which is very useful for posture, since less load goes to your spine. Shoes fit with flat, minimally cushioned soles. But try to walk barefoot more often!
Here is the secret of my grandmother (literally!), who was brought up at the very beginning of the twentieth century, when good posture for women was strictly required.
We take a thin stick about a meter and a half long. We lay it behind the elbows. In this state, we walk, sit, watch TV - how long we can endure. And so several times a day.
Checked for yourself! It is completely safe, has no side effects, 100% effective.
