In this video from fatlosslifestyle we learn how to widen your shoulders and upper back with a few exercises. This is a workout you do twice a week. First is a dumbbell overhead press. Bring dumbbells up to starting position, turn palms in to face a bit. Keep dumbbells above shoulder lift up. Don't let the dumbbells touch though when you bring them above your head. Repeat this action. Find a weight where the last 3 are difficult in the 12-14 range. The next exercise you need a flat bench. This is a one armed dumbbell row. Rest one hand on the bench while with the other you bring it up in a row. Repeat this action with the other arm.
