It's only been 3 days, but I'm really enjoying going to the gym and I actually look forward to it every day! I've only been using the treadmill because I'm too anxious to go to the free weight area just yet, but I'll build up the courage to in time. Right now on the treadmill I'm doing 10% incline, 3 mph, and working towards going for 40 minutes. I'm only at 25 minutes so far, but it really does get easier every day since I could barely do 15 on the first day and 3 mph felt way too fast-- Now it feels too slow! Every day I make myself do 5 minutes more than I did the day before and it feels good to see the progress. I'll keep doing my best.
