Noob! Looking to live a healthy lifestyle

Hi! My name is Amanda. I'm 26 and live in Nova Scotia, Canada. I joined the site a few weeks ago and thought it might be nice to have some friends and a support base to keep me motivated! I'm a bit of a computer person, so I spend most of my day at work sitting in an office. After several years of that, I am looking to get back into shape so that I feel better, both mentally and physically. I'm pretty determined but some help would be reassuring!
