As you all know, one of the keys to exercising do something you enjoy. For me, I've gotten in to tennis. I'm lucky to have a court right across the street from me. Every chance I get, I practice my serves. Unfortunately it hasn't helped much. Tennis is alot more tiring than it looks. After a while, my right arm basically feels like rubber; however, I enjoy it, and it makes exercising enjoyable. That's what everyone should do; find something enjoyable so you won't dread exercising.
