I'm 19, 5'7'' 156 lbs. I've smoked for the past 6 years and I doubt I could run a half mile, I eat lots of junk food, and drink a case or two of beer just about every weekend. I want to get in shape now. My brother bought a smith machine. I want to get in shape but I have no idea how much weight to start with, how many reps to do starting out, how much cardio I should do, what I should eat or anything for that matter. Only thing I've done so far is give up the ciggarettes for the past week. If anyone could give me some info about how to start weight lifting, and also how to start running, as in how much to start with and how often I'd greatly apprecitate. It all seems so overwhelming, I need some way to get pointed in the right direction. I'd like to get lean at first, maybe build bulk later on. I'd really like to get rid of this beer gut.
