Everything that makes us feel good is neurochemical in nature, including exercise. Exercise can lead to a withdrawal period of feeling shitty and unproductive, and it can be quite addictive.
Really important not to confuse "feeling good" with being good for you. Have seen a lot of people overdo it and lose their lives to pointless exercise while accomplishing very little else. Also important to realize that most things in life that give you a boost in life also give you a debt to pay back at a later time/date.
