If you have facebook, I recommend a page called Getting Fit Now or Never. She is always posting motivational pictures and sayings. I'm so glad that I liked her page, because now I get a daily dose of motivation!
Hey! How'd they get a picture of me on an exercise bike?? LOL
There are lots of amazing pages about fitness on Facebook. I have like several of them (Never Stop, Shellys Belly, From Fat to Phat) and they all offer tons of motivation and encouragement. I think the best thing about them and SP is knowing you aren't alone in your journey.
