You can do this pose, recommended by yoga instructor Sara Quiriconi, either standing or sitting in your chair for a quick side stretch that releases the tension in your chest and upper body.
Stand or sit with your feet under your hips and interlace your fingers above your head with your palms toward the ceiling.
Lengthen the right side of your torso as your lean to the left. Hold this for five seconds, then switch sides. Repeat two to three times on each side.
You can also lift one arm at a time to focus the stretch on one side.
