How to take a yoga break at work
Maintain correct posture.
Before you do any office yoga poses, especially those you can do seated in a chair, make sure you're sitting with good posture. Move to the edge of your chair so that your feet can rest flat on the floor.
Generally you want to sit in a stable chair rather than a chair with wheels, if at all possible. If no non-wheeled chair is available, lock or block your wheels if you can so the chair won't roll.
