Interesting At Home Shoulder Treatment

I've had shoulder pain in my right shoulder for the past 6 years. It's gone through different phases and levels of severity as I am more or less aggressive with it. It has never been 100% though in the past 6 years. I've been visiting my chiropractor very regularly for the past 2 months looking to actually find a solution to the problem and I have noticed gradual improvement. 

The improvement seemed slow and my shoulder still felt very weak. I started searching for additional things I could do to speed up recovery and I came across a book on Amazon  that discusses the causes for most shoulder pain and how to get rid of it without surgery or complex physical therapy. The book is written by John Kirsch, an orthopedic surgeon that has been researching his unique shoulder treatment for over 25 years. 

The basis of the shoulder exercises is built around the simple practice of hanging from an overhead bar, like a pull-up bar, with your palms facing forward. Supposedly this places your shoulder in a very safe and relaxed position that also puts pressure on the subacromial arch. This arch is what seems to creep down over time and creates a cramped space for your shoulder to perform its usual activity. By regular hanging and a few other simply light weight exercises he claims that you can strengthen your shoulder and avoid most other shoulder treatments. The reviews are what inspired me to try this. I haven't found one single negative review for this treatment and there are a ton of people who are raving about their success with this simple treatment. I've been trying this out for a little less than a week and I have already seen improvement in strength and range of motion. I don't feel like I'm back to normal by any means, but I do feel like I've found something that will help my overall shoulder health long term and allow me to throw a football and baseball without pain.
