HOW: Start in a standing position. Begin the exercise by holding a weight or an object overhead in one hand while holding another weight or object in the other hand by your side. While maintaining good arm and shoulder blade position to stabilize the objects, walk forward.
FEEL: This should feel like a full body workout, especially your upper back and shoulder blades working to stabilize the objects. Keep your shoulder blades squeezed up and back together to 'pack' your shoulders.
COMPENSATION: A little shrug is ok, but do not excessively shrug. Think of positioning your shoulder blades up and back. Do not let the objects or your body sway too much, try walking in a straight line.
