nutrition/exercise websites

here are a couple of websites i think are pretty cool that help track nutrition and exercise - and they're free to use!

Sparkpeople.com

CalorieCount.com

Both really are quite comprehensive and have an extensive food library if you like to track food/calories, but still have the options to enter in a food not listed. They also have ways to be involved with other members in a very non-intrusive manner. They also try to send out fun/useful information regarding health/wellness/nutrition/exercise/etc. Anything from current studies and their results to tips on how to do different exercises.
