I am trying to improve my shoulder mobility as holding a weighted bar behind my back and lifting up 90 degrees to horizontal is something I struggle with. I have been working on it for over 2 months now and still cannot elevate fully enough to progress. Does anyone have any thoughts on what exercises and stretches I could do to try and gain this last bit of mobility I need to get to horizontal?
Currently I use a broomstick with very wide grip to lift up behind, hold just above horizontal and stretch out my chest, I then bring the grip in by increments and do the same until I cant do it anymore. I also put my hands on a kitchen worktop behind me, squat down and try and keep my arms straight behind me as my shoulders drop, stretching it out this way.
I have definitely improved since when I started by a fair margin but I have hit a bit of a plateau now and dont feel I am progressing any more. What can I train to improve this?
