Answer:
- exercise strengthens our muscles in our body,it helps your heart muscle to become more efficient and stronger.
- Just as exercise strengthens other muscles in your body, it helps your heart muscle become more efficient and better able to pump blood throughout your body.
- This means that the heart pushes out more blood with each beat, allowing it to beat slower and keep your blood pressure under control.
