I've recently started to pay importance to fixing my bad posture which I have developed over the years. I've been working out regularly (weight training for 4+ years), but have always neglected stretching. However, I've started stretching after each workout. Have started to strengthen weaker muscles, fixing my rotator cuff issues , trying to strengthen rhomboidal,elongating my hamstrings and strengthening my neck. I observe that my left shoulder scapula is higher than the right, indicating a rounder shoulder on the left. Additionally, I feel pain/discomfort when I raise my left hand above ahead (like an impingement) What I need: a correct posture which can be sustained life long and all muscular imbalances corrected so that I can focus on building my body in the right way
