I worked out in high school and got to about 180. I'm not going to lie..I was basically doing it for the girls. At that age chicks dug that. It's also a very easy way to get peoples respect. Sounds stupid, but you'd be surprised how much people treat you differently when they see you after you been working out for a while (girls, guys, teachers, family). I'm not even kidding..it's like, are you guys serious? You're really THAT affected by the way I look?
It's not too hard to get big...the hard part is finding that motivation inside you and sticking with it. Finding that drive inside you is what was important. I didn't want to just look bulky, like the guys able to lift crazy weight. That just makes you look not very intelligent .I wanted to look strong too, but more cut, defined.
I started lifting weights, going to the gym about 5 days a week. I had 2 workout buddies. I played sports also, but I had separate guys I worked out with. I knew I'd be taking off to college..UC Santa Barbara..I knew my lifting weights wouldn't hurt there either

It certainly didn't.
Basically this is what I did:
-Start taking Creatine now. I used "Cell Tech", manufactured by MuscleTech. The stuff is kinda expensive, and I know they've come out with new stuff since then, but this stuff still works. Hardcore. Cell Tech you take AFTER your workout. Creatine serves a double purpose: getting you much stronger because you're able to lift much more weight..but more importantly, you get results FAST. And results mean you get WAY more motivated. Cell tech gives you 75g of sugar (dextrose) as well..it's not creatine monohydrate..stay away from pure creatine...it won't do NEARLY as well because your're body isn't able to absorb nearly as much creatine with out a delivery system (dextrose). That's why you supposed to drink creatine monohydrate with grape juice and shit. But it doesn't get absorbed well.
- Start working out 3 days a week for the first month. At the beginning, any time more than than 3 days a week you are not giving your muscles enough time to regrow.
-After a month to 6 weeks, start working out 5 days a week.
-Do your back and bicepts on one day, and the next day work out your chest and tricepts. Continue this alternating schedule for as long as you working out. Alternating days gives your muscles time to regrow (when you are asleep). Make sure you get do your legs too and you look like a moron if you got big upper body and skinny legs.
-Eat a ton of protein. Buy protein powder from costco, drink that and milk like there ain't no tomorrow. Try to get at least 100g protein a day. Eat chicken breasts, cottage cheese, milk, etc.
-After you've been working out for a few months, start doing 20 min of cardio a day - This is the thing that everyone wants to skip, but if you do 20 min of cardio in addition to lifting weights, you will look better than 99% of the people at the gym. You're veins will stand out when you lifting weights, and you will look CUT.
-I took this stuff called Xenadrine for energy. I actually took it for a few years as it helped me concentrate. I took it back before ephedra was made illegal, so it worked great. Improved your energy and concentration. Took that shit before the SAT's, doing homework, etc. I don't know what works now.
Summary: find a drive inside you, drink creatine (5-10g), workout hard(5 days a week), eat ton of protein (75-150 grams a day), add in an energy supplement if you want, do cardio...get laid.
That's all I could think of for now. Let me kow if you want any more specifics but that's the basic outline that worked for me.
