So..
I tried protracting more in the pushups. I had to rearrange somewhat after each rep because I had the feeling that while trying to get some thoracic flexion I was losing my PPT even though my abs and butt were tight and contracted all the time. As far as it goes with the protraction, I really have the feeling that I do protract as much as I can, but I think my kyphotic curve is somewhat flat thus making it hard to look like a "turttle" in the upmost position. You will see in the video if any progress is done.
Rows.. hmm... I tried as suggested to put my shoulders directly beneath the rings, but as it can be seen, something ain't right. If my shoulders are there and my feet stay unmoved, I can't pull up.. it just feels wrong.
