Well I did manage to make it to the gym. I got 30 minutes of cardio in, walked almost 2 miles in that time and burned 226 calories according to the treadmill. The place was packed and my legs burned after the 30 minutes, so I left. I can remember a time when I could be there for 2 hours and not feel the kind of pain I'm currently feeling. It really sucks being out of shape.
