Gym Update

Went to the gym this morning and did 45 minutes of cardio (2 miles in 40 mins)then did 15 mins on the machines. I'm sure I sweat out about 3lbs- lol.... When I came home my weight was back down to where I was last Friday, and before this weeks gain. So now I only need to lose another 2 lbs before Monday's weigh in ***sigh****
