If there's one muscle group that can truly set you apart from the rest of the pack, it's your shoulders. Unlike most muscle groups, the delts live in three dimensions, with heads in the front (anterior), sides (lateral), and rear (posterior). Whether you're wearing a tank top or a suit jacket, a pair of well-developed shoulders is noticeable from any angle. No other muscle screams “I lift hard and heavy” like the shoulders do.
But as the saying goes, with great power comes great responsibility. If you want your delts to stand out in a crowd, you need to train them evenly, work to eliminate muscle imbalances, and strictly focus on your form.
Make sure you are avoiding these five mistakes, and your shoulder training will produce the big results you've been looking for.
