Every exercise regimen should include warming up and cool down because both are important to reduce the stress on important organs like heart.
Warming up of the body is important to prepare our body for a cardiovascular exercise. It releases the stiffness in our muscles and increases the blood flow in muscles which provides more oxygen to the muscles. Warming up is necessary to protect the body from injury.
Cooling down after the exercise is equally important as warming up because it allows the body to recover gradually from high blood pressure and fatigue. Therefore the correct answer is true.
