What Are the Muscles in Our Shoulder?
The human shoulder joint (or rotator cuff) is a very complicated joint and it is composed of many different muscles and tendons. In fact, you can injure the rotator cuff without even knowing it. Everyday activities can cause your muscles to tighten and tear off the shoulder capsule. This is why it is so important to always keep proper form when exercising and not strain your muscles. It is also one of the reasons why you should ensure that you regularly stretch when sitting at a desk for long periods of time and make sure that you are sitting in a proper Operator Chair like the ones from Bestbuy Office Chairs
