SuperBaby! Liam has a rare genetic condition called myostatin-related muscle hypertrophy, or muscle enlargement. The condition promotes above-normal growth of the skeletal muscles; it doesn’t affect the heart and has no known negative side effects, according to experts. Liam has the kind of physical attributes that bodybuilders and other athletes dream about: 40 percent more muscle mass than normal, jaw-dropping strength, breathtaking quickness, a speedy metabolism and almost no body fat.
