Allright, I'll help you out. This is how I started when I was around 14ish.
A couple of things first. The reason why I in general started working out heavily is because I was quite chubby as a child, and it annoyed me.(No more specifics there
).
My father was on the national team in his early years, and my mother was an heavy running athlete. Both had very good bodystructures and so.
This might be why my body is the way it is. I'm one of the special people who have a very heavy structure specially over the upper back and also my body system is a bit different then normal. (Meaning, I can lose weight much faster then an avarage person, something to do with my combustion/incineration,(sorry , dunno which of the words is correct).
This allowed me to achieve what I wanted much faster , oh and by the way I did running minimal, for those of you who wonder.
I didn't really like running at all, so I decreased the weight of two or three of the exercises which give you the same results running did.
What I mean is, I decreased the weight on them so that I could do alot more of them, and trust me, I reccomend running xD.
Anyway, the diet you would want to do is simple. Normal proteins are very easily obtained, and do no damage to your body, no matter how much you eat.(Well if you eat too much of anything you'll die xD, but not the point.).
Your stomach can't take any type of eggs? If that's the case, auch, really auch. I used to mix eggs with juice and held for my nose alot, the protein is very big ;p.
Anyway, eating alot of protein is really not that important at your age, as that your body is still under heavy development (unless there are some physical speciallities which make you "different") you should ease down on the protein eating, and concentrate to get as much resources of everything as you can.
Start your days like this :
Wake up two hours before school every day including saturday and excluding sunday, and run slowly. At the first three weeks, really you need to relax. If you overpush yourself, You will get muscledamage and won't be able to run for about a year. So the first three +/- weeks run 3km (No clue how much that is in american so calculate it yourself ;p). Drink alot of water! Remember that, water is your key to success! Every meal you eat, drink at least one liter of water gradually as you eat. Keep away form chocolate and soda specially, and mostly any type of sugar bombs.
After you finish running, Go shower (do not do any other exercises to start with after the jogging, only jogg the first weeks) and go to school or if it's a saturday do whatever you please (except eat anything else besides a good healthy breakfast with alot of water!).
Now, before you go to sleep, go running again the same amount, and do no other training. Keep this up for 3 weeks, give or take.
Now, continue exactly the same, but increase your dosage of KM by 2, and after your done running , do pushups / situps / and kneebends. I don't know how much your body can take of these, so you'll have to find a decent amount yourself. Remember NOT to overdo it, otherwise you'll have to restart and half the **** will go wasted.
Keep doing this for 5 weeks.
Now your about as ready as you can get to start working in the gym, this is where you schedule takes a full swing.
You will no longer be running 6 times a week, but only 3.
Tuesday, Thursday, Saturday will be your running days (now run 8km and do the exercises) while on monday, wednsday, friday will be your gymdays.
At the gym, you need to get a programsetup, and a notebook to write all your exercises for every time. Personally I had a program upset by a trainer, and I really can't translate it to english, but do 10 types of exercise, for every bodymuscle you have, and again , do ___NOT___ overdo your limits. No matter if there are girls around or anyone you want to show off to, f*ck that.
Keep doing this for 5 months, and tell me how you look =). (At least this is around how I started, and I was 14).
I lost 25kg after 5 weeks, and my body started taking heavy shape.
GOOD LUCK! *kissis and roses*
