For starters, a little about myself. I am 53 years old, 5' 11" and 190lbs. I have been actively training for the past 25 years. During the past two years, predominantly with both kettlebells and a mixture of bodyweight exercises. Last spring, I purchased both the XR and BtGB. I have read the book several times and have dabbled in developing a workout plan while still maintaining parts of my kettlebell routine.
Unfortunately, a shoulder issue, minor tear and frozen shoulder diagnosis, has made me limit certain exercises with the kettlebells. That being said, I have developed a plan using the principles of BtGB that I am comfortable with and have seemed to help loosen up the stiffness in the shoulder.
Below is the plan that I have been using for several weeks now. I would appreciate any feedback, suggestions and comments-positive or negative that will help me move forward in getting stronger.

Is this plan excessive, within the confines of the principles of BtGB or in needs of some form of modification? Thanks for your time and support. I am truly enjoying the XR. 
They make for an enjoyable yet interesting challenge.
