For people looking for motivation to work out more often. This one's got a monetary element involved.

Currently only works for the iOS devices although it seems like they have a HTML 5 component in the work to allow ppl to check in from the web and an android app for android device owners.

Enjoy !!!

I recently saw this blog post about Gympact:

I'd really like to try it but it's only available for the iphone right now. As soon as they have an android version, I'm in! Think of it as helping to cover some of the costs of your gym membership!

I've also heard of two other sites that can help you stick to any resolution:
