In: Biology

Answer 1

In addition to the other comment, the type of muscle that surrounds blood vessels is called smooth muscle. the ‘smoothness’ means it can not be strengthend or enlarged like skeletal muscle can. Skeletal muscle can be strengthen because it’s striated, smooth muscle is not. To gain strength more muscle fibers are needed, enlarging the muscle by adding more fibers (striations)

Aside from that, smooth muscle is completely controlled by our subconscious (autonomic nervous system) so we couldn’t exercise it anyway
