First, thank you for taking time out of your day to read my question.
Ive been lifting/training consistently for about fourteen months. I recently looked back at a few of my before pictures and have noticed a developing exaggerated postural/muscular imbalance between my two arms. My left arm appears more externally rotated and my right, more internally. Im quite certain this imbalance is due to poor form, weak-side/strong-side compensation, etc...
My question is: how can I best determine the root of the imbalance and how can I remedy it? My first thoughts are shoulder/chest compensation issues... but how can I be certain?
Ive attached a photo for your review. Again, thank you for your time and assistance. I appreciate your feedback.
