Hey,
So I believe I may have been doing this whole exercise wrong. Or at least something has probably gone wrong along the line. I have reached sPL/pe6 and HBP/pe5. When I did sPL/pe5 and HBP/pe3 I believe I had it going good. But in HBP I seem to advance pretty quickly but in sPL I now seem to be regressing (in contrast to progressing). More and more I have started to feel the load of the lean in the "shoulders, biceps bracchi, and the forearm/finger tendons", and losing the feeling in the scapula/shoulder blades. At the moment I can not find the proper feeling at all unless I have my knees on the ground and lean very very slightly forward and deliberately and slowly searching for the scapular muscles. What I have noticed recently is that it seems as though protraction and depression is not enough. I can protract and depress but without shoulders rotating forward I get absolutely nothing from the upper back but instead only as mentioned above: shoulders, biceps brachi, forearm...
So now I have mixed feeling. Although it is sad to have to start over it is a joy to have learned alot along the way. What I am interested in is whether anybody has experienced the same thing? If I have understood this exercise properly then I wish that this information about rotation also was available and not just protraction and depression.
