gym workout

i just got home from the gym, and I have to say, I did pretty good for a first-timer. I've never been to any sort of cardio/workout class, except P.E. in school. I did 2.5 miles walking on the treadmill, and I got 1.18 miles on the bike, and I did 5 different lifting machines. I didn't sweat, so my Aunt Missy says I need to push myself further and harder, so I'm going to put the incline on the tread when I go back tomorrow morning. I'll update later on today or tomorrow.
