Hiya - just wanted to introduce myself. I've been reading Fitness magazine off and on for a while now. I'm trying to get back into shape after falling off the wagon for a while. I have pretty bad knees and I used to run a lot, so it's been difficult to find something that keeps me as active. Anyways, looks like a great community and its a great way for me to keep myself motivated. Looking forward to chatting with you all!
