This seems really interesting exercise. For sure I will add it in my shoulder's workout
Chest, arms, shoulders. We get it. You want to like what you see when you catch a glimpse of your own reflection. Step onto any gym floor, you’ll see guys tackling exercises from bench to shoulder presses hoping to cut a frame that looks good inside and outside of a shirt. One exercise worth adding to your chest and shoulder routine? The Arnold press.
