The shoulder joint is the most mobile joint in the body. That’s a good thing! When combined with good spine mobility, our shoulders allow our arms to reach, throw, pull, and push from all sorts of angles.
A consequence of being mobile is the possibility of being highly unstable. Instability, or the inability to control a limb, may lead to the common aches and pains that many of us experience in our shoulders, elbows, and possibly even the wrists. Why might instability and pain happen? (My answer will be limited to chronic pain, not acute injuries such as fractures and dislocations due to falls and other accidents.)
My belief is that shoulder problems (and most other movement problems) are rooted in a use-it-or-lose-it dynamic. Our modern lifestyle is characterized by limited movement. As adults, we rarely crawl on the ground. As modern humans, most of us don’t have to climb trees or pick up heavy things and put them overhead. We typically sit with our arms in front of us as we type on keyboards, drive cars, and operate TV remote controls. Thus our movement skills stagnate. Our brain and nervous system loses the ability to coordinate the many movements available to us. But then we might decide to swing a golf club, swim, lift weights, attempt pull-ups, pushups, throw a ball, or reach into the back seat from the front seat. Unfamiliar movements—especially if done with high force, high speed and/or done at end-range—may be too much to ask of our deconditioned shoulder complex. Then we get pain.
The following videos are designed to help restore mobility and stability to the shoulders. Pay attention to how you move as you do them. Don’t speed through them. Always be in control of the exercise, don’t let the exercise control you. If it hurts then back off or stop. None of these drills are guaranteed to fix any specific problem you may have. You may need to see a physical therapist or some other injury rehab specialist.
For the corner stretch, keep you eyes up a little bit. Don’t let your head and neck flop forward.
For the rotator cuff complex, use high reps, maybe 15-20 reps.
The halo can be varied in some ways not shown in the video. Try the halo while in a hip-hinge or deadlift-like position. Use a light weight.
