Answer:
because if you dont you can work your muscles a little too much and you always wanna keep your heart beat down so cooling down helps with that. gradually cool body temperature, return muscles to their optimal length-tension relationships, prevent venous pooling of blood in the lower extremities, which may cause dizziness or possible fainting, and restore physiologic systems close to baseline.
Answer:
It allows the heart rate to return to its normal rate.
Explanation: It doesn't always help with flexibility or strengthing your muscles, and since your cool down occurs at the end of a workout, it does not prepare the body for the rest of the workout.
Hope this helps! :)
