This simple yoga practice consists of four 5-minute stretch breaks that you can do whenever you have to sit too much. It is designed to release tension in the areas that get tight from prolonged sitting: lower back, upper back and hips. You can do each part individually whenever you get up and move around, or you can combine them any way you like. The entire practice is done in standing position, so you don’t need a yoga mat or any other equipment. It is best to take your shoes off, though.
