1. Try to sit up straight and keep your back straight.
2. Make sure you are using a chair that supports your back.
3. Use an ergonomic keyboard and mouse, if possible.
4. Adjust the height of your monitor so it is eye level or slightly below.
5. Sit on a cushion or pillow to provide extra support for your lower back.
6. Take regular breaks throughout the day.
