Can you answer J’s question about Bodybuilding?:

I’m a mid-twenties woman and just getting back into excersizing cause I am really fat. I need to lose about 30 lbs and tone all over, but I don’t know how to do it. I want to try weight lifting, but I have never done it before, and I have a lot of questions:

Is it better to do many reps with low weights or a few reps with heavy weights?
I usually jog a couple miles 3 or 4 times a week. Should I do this before or after lifting?
Do I need to warm up or stretch before I start lifting?
How many times a week should I go to the gym?

I am completely lost. Any advice will help!
