These are very simple exercises and I really only use these in the beginning to try and restore basic function before trying to move onto the more integrated movements that will have a better effect. Having said that they can be very useful for the person who is pretty stiff and sore. One thing I did not include that I often use between sets of these is releasing of the pec minor and the latissimus dorsi. Both of these muscles can play a part in ruining your attempts to strengthen the lower traps via muscle inhibition so make sure you include something for these muscles.
