A contrarian caution on exercise worship:

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.

I would be hesitant to call it pointless if it makes them feel good.

It's pointless because of the hedonic treadmill. Any feel good feeling is neurochemical in nature, and any moment of feeling good will be counterbalanced at one point or another.
