This exercise is another one of my favourites for building better and stronger posture. While pulling the arms back it’s extra important to keep the stately posture and add the active pull of the ribs down as not to overwork the upper back and push your ribcage out instead of working the shoulder muscles.

As you’re working one arm upward and one arm downward this exercise is perfecto to connect the muscles (extensor muscle slings) on each side of the spine to build strength in them.
