Bruises are from tears/ruptures in blood vessels. Muscle growth is from tears in muscle tissue. You can tear muscles without tearing the blood vessels around them. Its like if a part breaks but it’s still hanging by the wiring, because the wires inside are still intact – except in this case the wires are your blood vessels.
