Supraspinatus…Thumb Pointing Down!!!

After a warm-up in the gym I went through the eccentric shoulder exercises as follows:-

External Rotators: R/H shoulder weaker than L/H shoulder while doing this exercise by a fair margin.

Internal Rotators: No real difference in strength between the two shoulders but stability of the R/H shoulder is noticeable.

Supraspinatus: I have been doing these incorrectly previously as I did not point my thumbs down.  When i did point my thumbs down L/H shoulder worked fine but the R/H shoulder would not fire!!  It immediately caused pain and almost shoulder collapse, like my shoulder wanted to roll forward and cave in.  I found myself leaning forward and trying to do what would resemble a Donkey Kick-back.  Clearly this is an issue and other muscles are trying to take over to compensate.  After a few efforts and even another practice run with my L/H shoulder I finally got this muscle to work but it was rusty and stiff and managed about 5-6 decent repetitions and could do no more.

Serratus Anterior: Carried out 2 sets of ten for each arm and found it reasonably comfortable but R/H shoulder was weaker.  Experienced a pulling sensation or cramp on rib cage below scapula while doing these, possibly due to back work yesterday?

 

After doing the Serratus Anterior exercise my shoulder position/stability, while performing Biceps EZ Bar Curls was better than I have experienced for a long while.  This could be due to the last exercise or a culmination of doing them all over the last week.  I will try just this exercise in between my next Biceps Curls and see what happens.
