What is a good workout for me?
 

I just recently joined a gym and I don't have the money for a personal trainer. I have no idea what I should be doing with these machines and what not to do. I'm 17 and I weigh around 160 pounds I'm 5'5" and I would like to lose 20-30 pounds this summer. I'm already trying to stick to the 1200 calorie a day diet, but that isn't working out as well as I thought. They have basically every machine there is at this gym for cardio and weight lifting. I want to mostly lose my stomach, butt and thighs, but I could also use some more muscle in my arms. What machines/weights should I be using, how often should I use them? I really need specifics here, I have no idea what I'm doing. Also, they have a sauna at this gym, should I use this before or after I work out? Thanks.
