Let your desk help you stretch and strengthen your legs, arms, and spine.
-Downward Desk: Stand about an arm's length away from your desk with your knees slightly bent. Bend forward, letting your hands touch the edge of the desk, keeping your back straight, and your knees slightly bent. Adjust your feet further back if you need to. Allow the weight of your head and your chest to melt forward, dipping toward the ground as your hips pull up toward the ceiling. Slowly straighten your legs and lengthen your spine as you inhale and exhale deeply. Hold here for 2 or 3 more breaths or as many as you need. Then, soften your knees a little, let go of the desk, and drop your hands. Now, gently roll up to stand.
