I am right handed so when I learned a scapular retraction cue, I was able to execute better and more with my right shoulder, and because of that, I exaggerated and overused it with my right shoulder.
After some progression I noticed that my right side became very weak; my pull-up numbers decreased very much, as well as my bench and overhead press numbers. Then I realized that my left latissimus dorsi was specifically bigger and stronger than my right one. After that I tried horizontal and vertical pulling with different shoulder and arm positions (like retracted, shrugged or protracted shoulder with pronated or supinated grip).
I have found that my shoulders should be a little bit shrugged to be able to start with slightly stretched lats to effectively then contract the lats, based on trial and error over 5 years. However because I wasn't very dominant with my left side I couldn't screw my left shoulder into it's socket so my left side improved a lot. There is a big difference between them now.
Despite thinking I found the right cue (to train lats you need to shrug shoulder a little bit to start with a stretched position not with retraction) I think I still have an imbalance so it seems this cue is not perfect.
So if you guys have some good advice or a cue to fix this imbalance it would be great very meaningful. This has been too long a struggle for me. Thanks for reading and everything 😊
