The short answer to your question is that the US Constitution was for both national and state power.
The US Constitution was designed "to ordain and establlish" a nation with a workable balance between federal and state powers. The Constitution was necessary because the previously drafted Articles of Confederation failed to endow the federal government with enough power to make it relevant. However, many in the Constitutional Convention feared that the creation of a federal government with any power would ultimately impinge upon the rights of the states, or of the people. In order to prevent that from happening, a non-exclusive Bill of Rights was drafted which guaranteed that the federal government would not impinge on the rights of the people or, in the case of the tenth Amendment, on the rights of the states.
In the Constitution the states were intended to have more power, and now National Government has more power but not as much power as a State government has on a State. In other words National government has more power to the country but the state government has more power to the state.

the division of power between the national and state governments
in the US, the Tenth Amendment to the Constitution
The anti-federalists opposed ratification of the U.S. Constitution. They believed that the U.S. Constitution gave the national government too much power. They believed that the state governments should have more power than the national government.
Federalism is never explicitly stated but it is embedded in the US constitution. As a result, power is kept in the states.
Balance between national and state government power
The U.S. Constitution oversees the distribution of shared power between the national government and state governments. Each of the 50 states can make its own internal laws under an independent constitution, as long as these are compliant with the national constitution. Exclusive powers are powers that are reserved either by the national government or by the state government, but are not shared between both.
All this means us power is shared between the central (national) government and the states.
The US Constitution provided a limited amount of power to the government and explicitly stated that any power not given by the constitution to the national government is automatically power of the state governors.
