Tips for getting into physical activity?

It's literally as simple as just getting up and doing it. I know it may feel like you don't want to, or you can't be annoyed with it, but say to yourself to just get up and do it. Literally get up and go do what you are going to do. Once you start moving, it's not as bad as you thought it would be. After a while it will just come as second nature and you won't even have to think about it.
