Try this: rest your arms at your sides, then look down.  Are your elbow pits facing forward, or are they pointing inward with the knuckles facing forward? If the elbow pits are pointing inward, your upper arms are internally rotated. Your body molds to what you do most often…your habits become your posture. Unfortunately, modern life doesn’t require our shoulder joints to move through their full range of motion. Instead, we spend much of our time with our arms internally rotated, for example, while driving a car (10 and 2), writing at a desk, and typing on a computer.

Go out for a walk and watch how people swing their arms. Some arms look like windshield wipers swinging in front of the body. Sometimes you’ll see one arm swing behind the body like they’re fanning away a fart.  …maybe they are, I keep my distance just in case.

In the picture below are two twins separated at birth; the one on the left was raised by gorillas (or raised in front of a computer, I’m not sure?)  That’s me on the right. Notice my clavicles are not in the ideal neutral (horizontal) position- this is from a lifetime of elevating my shoulders. I’m working on it, so cut me a break here. Horizontal clavicles are essential; if they’re in a V formation, the muscles around them are not in the correct plane, making it difficult for them to work as a team with the rest of your muscles, like keeping the head in the correct position (ears over shoulders). You also run the risk of cervical disk problems, upper back strain, and blood flow to the head.

“The shoulder girdle maintains the environment and geometry for activities in the thoracic cavity (those of the heart and lungs) and the health of the cervical and thoracic nervous system,” Katy Bowman, a biomechanist, said.

Okay, okay, I know I didn’t use the best form in these videos, but I’m working on it.  It’s a journey. Correction: I’m actually doing chin-ups, not pull-ups. I’m planning on working on Pull-Ups next.
