Hey guys, this is my first post here. I am a 14 year old boy who is 120 lb and 5'7''. My goal right now is really getting my muscles in shape. I have had trouble knowing how to start off. How many reps and sets should I do with what exercise (machine or standard weights). I can do whatever you guys advise because there is a gym locally! Also how many days would I have to visit the gym per week in your plans? Please help me out, thanks.
