This is a great site to do just that. I didn't have a large amount of weight to loose, enough, but more so than loosing weight, I wanted to get fit, be strong and challenge myself. I have done that and I will continue to do that.
There is so much information and support. Create a spark page so people can get to know you and you can start getting ideas, support and feedback from others. Check out my spark page and add me as a friend if you would like. I'd be glad to lend any support!
