Well this speedster physiology was originally intended to be a necessary "second" power, for speedsters so they can handle their own power. And since Super Strength needs to be able to lift heavy objects and be able to handle the pressure of their strength, therefore invincibility/Supernaturally Dense Tissue is basically the "second" power for Super Strength users.
