first thing you probably want to do is learn. Read as much as you can, there are hundreds of great articles on any kind of training-related topics (from nutrition to training programs etc)
Good place to start :
Successful training in a nutshell :
Eat right :
-small meals every ~3 hours
-protein with each meal (try to get ~1g protein per lbs of bodyweight)
-start with a big breakfast
Train right :
-around 25-50 repetitions per muscle group
-rest around 90-180 seconds between sets
-do big compound movements that use many muscle groups at once (Deadlift, Squat, Bench, Chins/Row) rather than isolation movements
Get enough rest (~8 hours sleep per night)
Stop immediately if you feel pain in your joints/tendons/ligaments
If you want to do cardio, be sure to do it on your non-lifting days or at least with ~6 hours rest in between.
If you have any more specific questions, be sure to ask
I would like to grow a couple of inches taller, and some weights would be great to boost growth hormones.
I am unaware of any significant influence of weightlifting on your height (other than you would maybe gain a little by correcting posture problems ans standing actually upright)[/quote]
Ya can’t really get it any more easy than that.
Be sure to have a positive attitude and every time you walk into the gym you’re there to train.
Train heavy, and if you can keep a log of your workouts do so.
I would say don’t worry about losing weight considering you don’t weigh much to begin with, just focus on getting bigger and stronger, and once you reach a respectful weight, you can then cut excess fat.
