Is it possible to become addicted to exercise?

yes you can. I personally was obsessed with excercise.I would wake up at 4 in the morning and end up working out until lunch time. I would eat lunch then end up going to work out from 7pm to midnight. everyday i did this until a doctor told me i had to flat out stop. I was losing 5 pounds a day. now i excercise at a more reasonable pace.

Yes, I think it is possible to become addicted to exercise. Everything can be done to much. Everything should be done with moderation.
