Aw, man! That totally blows!
I am going easy on my work outs because I just hate seeing the scale going up because of muscle weight. I just jog/walk briskly 3-4 times a week because I know I can go overboard and then get frustrated with the numbers on the scale. And for some reason those numbers mean the world to me. I'm hoping that once I'm closer to my final goal I'll work out more often and do more strength workouts .
Hang in there, though, if your clothes fit better you're doing something good!
