I started today and was a little bit shocked at how out of shape I am

towards the end I was groaning and gasping like I was about to keel over and die... Having my husband as a very amused audience didn't help any. Anybody want to do the challenge with me?? I plan on taking before and after pictures, very curious to see if there will be a significant change. I have a wedding coming up and my goal is to fit in the dress that I have in my profile picture (18lbs ago). Feel free to add me as a friend, that way I'll feel less all by my lonesome
