Chair Yoga Tutorial: How often do you do side bends in your chair? Seated side bend / Crescent; stretches and strengthens the side of your torso (obliques as well as your lats) opens your chest and helps you to find your edge in your chair. If you are not used to side bends, it may feel uncomfortable or even hard. The more you do this, the better and stronger you will become. Playing with your edge, seeing how far you can bend to the side will help you feel more confident and comfortable in your chair. This is a great move for Seniors as well as those of you who spend hours in a chair to do on a daily basis.
