I'm impressing myself!

I feel really really sore and it would be so easy to give up. for four weeks now I have been going to the fitness center on my lunch break at work at least 3 days a week! And I am making progress, for one I am being consistent and I am finally pushing myself hard!!! It would be so easy to give up. alot of the days I am like I don't feel like going to the gym....rushing over there, changing clothes getting a spot in class, doing the exercises effectively, rushing to take a shower and get back to my cube all hot & thirsty. But I'm doing it and I always feel good after. Yesterday when I was on the elevator gym bag in tow a co-worker said to me "wow you are really dedicated." I just SMILED and said "yeah, finally."
Although I have not weighed myself I am feeling smaller. I can tell I have lost inches. But I'm doing it and I'm happy!!
