I take 3 classes with weights, and do weights on my own 2x a week. Mostly my own free weights, sometimes the machines. The heaviest free weight I ever use is 10 lbs. I'm 5'4", 118 lbs. That being said---I've got big arms. For some reason the muscles in my arms just get big! I don't feel manly or anything, but I've definitely got bigger arm muscles than all the girls I know (some lift weights too). But I don't look like a body builder and I'm not worried about getting big all over. I'm not ripped, and have no veins popping out. And I don't beat myself up about it because I don't mind having arm muscles! I'd rather be strong. I think weight lifting is an excellent thing women can do. Keeps them strong, keeps their bones strong, and is a good way to get out some frustration (which I am full of lately).
