I know alot of people don't have money for a gym, or whatever reason they don't have access, and those right there are some of the best things to do to get in better shape, without wearing your wallet out. Jogging, jumping jacks, and even jump roping are great ways to get your heart going.
I've been making sure to eat and drink better too. I haven't had a Diet Coke in a looooong time, so I guess im a recovering addict. No soda, no potato chips, candy, sugar of any kind as much as I can avoid, etc.
So far, so good. :)
