It starts pumping more blood.
Resting heart rate goes down (maximum stays the same).
Regular physical activity strengthens heart muscles -- and people who are inactive are twice as likely to suffer from heart disease as people who are physically active.
Cross-striations form cardiac muscle. The crossed formation makes the tissue and muscle stronger.

skeletal smooth muscle neuron
Smooth cardiac muscle.
cardiac muscle cells are joined by intercalated disks.
Cardiac muscle is involuntary striated muscle. The cells of cardiac muscle have only one nucleus. The layer of the heart that contains cardiac muscle is called the myocardium.
Most of the myocardium is composed of cardiac myocytes.
cardiac muscles/involuntary muscle
Your cardiac muscle never gets tired, and it is the only muscle in it's category. Your skeletal muscle gets tired many times, and it has many other skeletal muscles in it's category. Your cardiac muscle is also a lot stronger than you skeletal muscle.Sorry, also your heart is an involuntary muscle. We have no control over it. Whereas skeletal muscles are voluntary, we decide to move them or not.
