Cardiovascular strength and endurance, muscular strength and endurance, flexibility, walking, swimming, strength training … it's a lot of information that all adds up to one important point: you need to move it, or you'll lose it.

On the other hand, creating your easy fitness life will bring you happiness and a better life.
