You might just be surprised at how much you love it. Check out Starting Strength from the library and give it a good looking over before you get too serious. Also The New Rules of Lifting for Women has good information (The workout looks unnecessarily complicated to me.).
And don't let personal trainers try to convince you that women should only lift weights that weigh less than their purse. How did that idea ever gain acceptance?! It's a rare woman who gets bulky, and it would certainly take enough time that you'd notice it first. And really, who cares? I, for one, am already bulky! At least you won't be bulky, weak and in pain.
I just started early May, and can deadlift 110 lbs (one time! lol!). I've had a shoulder injury, so I'm taking it slow. (Really slow with overhead presses.)
Oh, and check out her vids. If that's not soft and feminine enough for the masses, too bad. I bet she eats too. :thumbup1:
