Le passage:
Terminology isn't the only thing that's misunderstood about shoulder training. Many people use completely unbalanced shoulder programs. A study showed that bodybuilders have front delts that are on average five times bigger than sedentary people. But their lateral delts are just three times bigger and their rear delts a mere 10 to 15 percent bigger. (Gundill, 2002)
