>>Tips to balance your muscles and prevent upper body injuries
The Problem Your front deltoids are much bigger than your rear delts, resulting in a lopsided appearance and a round-shouldered look. (Tight Pecs can also trigger the condition.) In addition to your gorilla like appearance, rounded shoulders may lead to a nerve impingement or tendonitis.
The Solution Follow a ratio of 3-to-1 between pulling and pushing exercises. For example, if you’re going to bench-press one day, make sure to do chin ups, rows, and bent-over lateral raises, or similar exercises at some point that week. Depending on how imbalanced your shoulders are, you may need to cut back on your pressing exercises even more.
You can stretch your front delts and pecs using a door frame. Bend your elbow 90 degrees and rest your forearm flat against the frame – lean forward slowly through the doorway so that you feel a stretch in your shoulders and chest. Hold for 20 seconds. Stretch both sides often.
